Mario Tennis Aces is a multiplayer sports game for the Nintendo Switch and the eighth installment in the Mario Tennis series. It is also the first game in the series since Mario Tennis: Power Tour on the Game Boy Advance to feature a story mode, in which Mario must advance through a number of missions and stop a powerful tennis racket, Lucien, from destroying the Kingdom of Bask, the game's setting. While the gameplay engine appears to be based on that of Mario Tennis: Ultra Smash, it refines the traditional tennis gameplay of the series by introducing several new techniques. One of the prime features in this game is an energy gauge which can be charged throughout the course of a match by rallying the ball. Energy grants the ability to slow down the time during a match in order to catch a ball more easily. Under certain conditions, it can also be used to stop time and launch the ball from a first-person perspective to the other side of the court through Zone Shots and Special Shots. These are powerful types of shots that can damage or break the opponent's racket if not countered correctly.

The game also offers expanded online features, mostly through tournaments and co-op challenges, where players can participate to unlock exclusive content. Since release, the game has been updated with new playable characters, story mode levels, modes of play, and tournament features, most notably a rank classification.

Gameplay

Basic gameplay

Mario against Boo in Mirage Mansion

As in a game of tennis, players have to hit the ball back and forth until one side misses it. In normal matches, players who earn a successful shot score 15 points; at 40 points, players earn a game point, and have to score another successful shot in order to win the game. A deuce commences if both sides are tied at 40 points, where they need to score a two-point advantage to win the game. There are two games in one set, with the number of sets depending on the rules of the match. A tiebreaker is used to settle the match if the players are constantly tied throughout the match. In tiebreakers, players score one point for each successful shot. Seven points are required to win the tiebreaker and, by extension, the match. If players obtain a 6-point tie, they need a two-point lead in order to win.

Matches can be played in singles, involving only two players, or doubles, involving two pairs of players. In every match, there is a server and a receiver, who switch sides at the start of every game. The server has to launch the ball on the opposite side of the court, otherwise it will be a fault. Two consecutive faults (double fault) will cause the opponent to score. The speed of the ball is briefly displayed at the top of the screen when it gets served. The ball has to stay within the boundaries of the field; if it lands out of it, the opponent will score. Landing the ball on the court's sidelines has the same effect in singles matches, but this is allowed in doubles.

Special features

Characters have an energy gauge that can be used to perform Zone Shots, Zone Speed, or Special Shots. The energy gauge can be increased by simple rallies, by charging shots, or by performing Trick Shots, which require proper timing to hit the ball back. Zone Shots can be performed upon reaching a rotating star point on the ground, and allow the player to aim their shot anywhere on the court using motion controls. The longer they take to aim, the more energy it depletes. When energy is fully depleted while in a Zone Shot, the stroke loses form, resulting the ball flying high in the air. Zone Speed allows the player to slow down time to allow them to reach a far-off shot in time. Special Shots can be performed from anywhere on the court and require a full energy gauge. Zone Shots and Special Shots are able to damage rackets. Rackets can withstand three Zone Shots or one Special Shot before breaking, and after being broken they are replaced with a new one, forcing the player to retire when they no longer have any usable racket. With proper stroke timing, these shots can be blocked, increasing the character's energy gauge and protecting their racket from damage.

In doubles, each pair shares one energy gauge, and if a player's racket breaks during a rally, that player's team immediately loses the point. Also in doubles, each player has their own racket counter. When playing in doubles, the match will end if just one player loses all of their rackets (no matter how many rackets that player's teammate has remaining) and that player's team immediately loses. Exclusive to doubles, the result screen also shows X marks in the sections where a player's racket took damage, and the X marks are colored as appropriate to show which opponent did the damage to that player's racket.

Other than the base style of gameplay, the game also includes a "simple rules" mode which excludes the new types of shots.

Types of shots

Shots can be charged to increase their power by pressing their corresponding button early before the player hits the ball. Max Charges result in powerful, quick shots that can push the opponent back. These can be countered with certain shots to reduce the push. In matches with standard rules, charging up a shot confers the player energy which can be used to perform Zone Shots and Special Shots. However, simple rules only allow basic tennis shots.

Basic shots
Shot		Description
Topspin		Topspins are shots that cause the ball to spin forward and bounce high. The shot is denoted by the red trail behind the ball. A Max Charge topspin can be countered with a slice.
Slice		Slices are shots that cause the ball to spin backward and bounce low. The shot is denoted by the blue trail behind the ball. A Max Charge slice can be countered with a topspin.
Flat		Flats are shots that do not inflict any rotation on the ball, making it move on a straight trajectory. It is faster than topspins and slices. The shot is denoted by the purple trail behind the ball. A Max Charge flat can be countered with another flat.
Lob		Lobs are high shots that send the ball far into the court. The shot is denoted by the orange trail behind the ball.
Drop Shot		Drop shots are low shots that send the ball close to the net with little bounce. The shot is denoted by the white trail behind the ball.
Star Shot		Star shots are shots that return the ball at high speed. These shots can be performed when the player stands on a Star Point, which usually appears on the ground when the ball gets sent high into the air by the opponent or when the player's energy gauge is filled one third. They are slightly more powerful than Max Charge shots, pushing the opponent behind when countered.
Leap Shot		Leap shots are weak shots that are performed when the character leaps for the ball and loses form. When the character leaps forward to hit the ball, it gets sent back at a low speed, and the character gains no energy. If the ball is sent high into the air, the opponent can strike it back with a star shot. Leap shots can cause the ball to land out of bounds or on the same side of the court.
Exclusive shots
Shot		Description
Trick Shot		Trick Shots are shots that involve the player moving quickly towards a distant ball to hit it, usually slowing time in the process as in a Zone Speed. Players spend energy to perform Trick Shots, but if their timing is right, they can gain energy instead.
Zone Shot		Zone Shots are shots that can be performed on a rotating Star Point once the player's energy gauge turns yellow. As of version 3.0.0, the Star Point also turns turquoise when the character stands within it. The ball can be aimed anywhere on the court in a first-person perspective, then struck with power. The opponent can successfully block a Zone Shot with proper timing. However, if the ball is hit too early or too late, the racket will be damaged.
Special Shot		Special Shots are the most powerful types of shots in the game. They can be performed from anywhere on the court, but only when the player's energy gauge becomes full. They will trigger a short animation which shows how the character is going to perform the shot, after which the player can aim and shoot the ball in a first-person perspective like Zone Shots. Unless countered with a block, Special Shots have the power to break the opponent's racket instantly.

Game modes

Adventure

Adventure Mode acts as the game's story mode, featuring cutscenes and levels like a typical Mario game. It is revealed that the game takes place in the Kingdom of Bask, which was destroyed in ancient times by a powerful tennis racket named Lucien. After being discovered and stolen from the Bask Ruins by Wario and Waluigi, Lucien is rewakened and proceeds to possess them and Luigi during a match on Marina Stadium. Lucien's motivation is to seek five Power Stones scattered throughout the kingdom, which conceal his true power. Under the guidance of Aster, a mysterious voice, Mario sets forth to retrieve the five Power Stones before Lucien and defeat him once and for all. On his journey, he must complete various missions and level up to become stronger.

Toad accompanies Mario throughout the jorney, acting as his spokesperson, as Mario does not talk. After selecting a mission on the map, a short dialogue between Toad and other involved parties will commence, then the player can begin the mission. Mario can exit to the world map or (as of version 1.2.0) retry the mission if the player pauses or fails it.

For more information about this mode's contents, see below.

Tournament

Tournaments are successions of matches (here also called rounds) in which the player can challenge computer opponents or online worldwide opponents in an 8-player bracket. They return from previous Mario Tennis games after being absent in Mario Tennis: Ultra Smash. Tournament matches feature up to three sets, each divided into two games. If players are tied by the end of these sets, there will be a tiebreaker that decides the winner of the match.

COM Tournament

Mario facing off against Daisy in the semifinals of Mushroom Cup

In computer tournaments, the player can choose to compete for the Mushroom, Flower, and Star Cups, each representing a different difficulty level. Computer tournaments consist of one preliminary round, semifinals, and finals. Each cup has a number of possible opponents that are selected from the game's base roster; in other words, they cannot be characters added after the game's release or characters in alternate costumes. The character used for winning one of these cups receives a small crown next to their name and under their icon on the character selection screen of that cup.

The table below lists all cups with the corresponding rules and opponents.

Cup	Rules	Possible opponents
Mushroom Cup	Round 1: 1 set of 2 games Semifinals: 1 set of 2 games Finals: 3 sets of 2 games Total rackets: 6
Flower Cup	Round 1: 1 set of 2 games Semifinals: 3 sets of 2 games Finals: 3 sets of 2 games Total rackets: 7
Star Cup	Round 1: 1 set of 2 games Semifinals: 3 sets of 2 games Finals: 5 sets of 2 games Total rackets: 8

Online Tournament

Players can connect to the internet to compete against other human players in online tournaments. In order to participate, players need to have the latest version of the game and a Nintendo Switch Online subscription. They can participate in the standard class, simple class, or (as of December 2018) the doubles class. For the doubles class, the player can pick a partner either locally or online.

As of December 2018, online tournaments consist of one preliminary round followed by a semifinal and a final round, similarly to how the COM tournaments are structured. Originally, tournaments featured three preliminary rounds instead of only one. In every online tournament match, there is one set with two games and (in the standard and doubles classes) each player has only two rackets.

Players can obtain rating points by winning matches, or lose points otherwise. The amount of points earned or lost in a match depends on the player's performance. Rating points determine a rank from D- to A+, which are used to match players of similar proficiency. If someone has rank B (2,500 points) or higher, they will start each tournament from the semifinals. When players enter a month's tournament for the first time, the points they had obtained during their last online tournament period played are rounded and kept for the current tournament period, along with their rank. Each tournament period keeps track of player statistics such as tournament wins, round wins, and round losses, with the latter two being calculated in a win ratio.

When the player wins a championship, they are congratulated with a trophy resembling the Special Cup from other Mario titles. However, unlike in COM tournaments, characters that are used to win an online tournament are not given a crown on the character selection screen.

Between July 2018 and July 2019, playing at least one match in an online tournament each month awarded the player with an additional character as a participation bonus. Starting with the January 2019 tournament, the player can also earn Participation Points, which can reward alternate costumes.

If a player disconnects or is disconnected during a match, the match will be forfeited and the opponent will win. Players who forfeit the match in this way too many times will not be permitted to participate in the rankings.

Co-op Challenge

Co-op Challenges were added as part of the version 2.0.0 update. In this mode, four players (which can be local and online) participate in a limited-time online event to earn points that can unlock alternate costumes and colors for playable characters.

The player can wait 60 seconds for the console to search and connect to other players. If not enough players are found in this timeframe, the game will substitute them with computer players. The player can choose to keep searching for online players for 180 more seconds.

For more information about this mode's contents, see below.

Free Play

This mode allows players to play custom matches at their leisure. Up to four players can join in Free Play, both locally and online. By pressing the or button, players access a menu where they can change the match rules, with the following options:

Match Type	Singles Only: Every match is 1 vs. 1. Doubles Only: Every match is 2 vs. 2. Singles and Doubles: Singles and doubles matches are chosen at random.
Doubles Partners	Random: A computer or human player is chosen at random as a doubles partner for the first player. P1 and P2: The second player is chosen as a doubles partner for the first player.

P1 and Random COM: A random computer player is chosen as a doubles partner for the first player. Note: Available only if Match Type is set as "Doubles Only" or "Singles and Doubles".
COM Difficulty	Players can select different proficiency levels for computer players: Novice, Intermediate, Expert, Pro and Ace. These determine how fast they react and build up energy. Intermediate players and up also often approach and remain near the net to hit the ball early.
Play Style	Standard: Players can gain energy in a gauge and use it to perform special moves. Simple (Beginner): Players can only use classic tennis moves. Computer players will send the ball at a moderate speed. Simple: Players can only use classic tennis moves. Computer players will send the ball at a higher speed.

Quick Play: A tiebreaker match, in which players have to score 7 points in order to win. Extended Play: Two sets, each divided into two games, and a tiebreaker. The player who wins two consecutive games in a set wins the match. A tiebreaker commences if there is a tie in both sets. Full: A single set-match divided into six games. The first player to win six games wins the match. If both players are tied at five games, a two-game lead is required to win.

¹ - In the "Change Rules" menu, the player can press the / button to set up their own selection of courses, where they can also turn hazards on or off for each course.

Swing Mode

Yoshi and Toad in Swing Mode

In this mode, players can use motion controls to play tennis. This mode is played solely with the left or right JoyCon, which may be chosen to depending on the player's dominant hand. During matches, the camera is positioned lower than usual. There are multiple features in Swing Mode, all of which only allow simple tennis rules (i.e. no Zone Shots, Special Shots or Zone Speed).

Regular Ball

Matches can be played with a regular ball, just like in Free Play. Most rule options from Free Play are also present here, though the player cannot adjust the Play Style and, by extension, the KO Loss. One added option is to activate the challenge system, wherein the player is allowed to challenge the decision that the ball was shot out of the court. Up to four local players can join a match in Swing Mode.

While rallying a ball, players can hit it a bit early to send it towards the corner on the opposite side from their racket (pull shot) or a bit late to send it on towards the corner on the same side as their racket (push shot). If the ball is hit too early or too late, it will be sent at a low speed (similarly to leap shots), allowing the opponent to strike it with a flat shot and return it faster than usual.

If players have enabled the challenge system, they will be allowed to challenge whether the ball bounced very close to the court's bounds and was called out by the judge. During a challenge, the camera zooms into the spot where the ball bounced, showing precisely if it landed in or out of the court. If the ball has merely touched the boundary line, it is considered to be in the court. If the challenge is successful, the call will be overturned and the opponent will receive no points, but if it is not, the player will lose one challenge. The player can incorrectly challenge a call three times, after which they can no longer challenge a call during a match.

Big Ball

Matches can also be played with a large-sized ball, which is slower and easier to hit than a regular ball. All basic rules and features seen in regular ball matches apply here.

Special Game

In this feature, players can play the Boo Hunt and Shy Guy Train Tussle minigames both cooperatively and competitively. Players can earn different high scores for each mode of play, and in cooperative mode, they also receive a rank based on their high score. By pressing the or button while highlighting a minigame, players can view the rules of that minigame.

Rally Challenge

Similarly to Mega Ball Rally from Mario Tennis: Ultra Smash, players have to rally a ball as long as possible. The game can be played with up to four players.

The ball starts out large-sized and moves slowly. With every 10 rallies, the ball's size decreases while its speed increases, changing colors to reflect this. If the ball lands on the sidelines of the court, it is not considered out, even if the game is played in singles. The game is over once one of the players/teams misses the ball. No high scores are recorded for this feature.

Change Number of Players

This feature enables secondary players to join or leave the game by synchronizing different JoyCons with the game.

Characters

Playable

The character selection screen, with all post-release characters available

Mario Tennis Aces features 30 playable characters, consisting of 16 characters available at launch and 14 characters made available post-release as online tournament participation bonuses. Of these characters, Spike, Chain Chomp, Blooper, Boom Boom, Pauline, Kamek, Dry Bones, and Fire Piranha Plant are newly playable to the Mario Tennis series. Some characters have unlockable aesthetic variations.

Like in previous installments, characters are split into categories of types.

• All-Around characters have very balanced stats.
• Technical characters have good ball control that can easily target corners on the court.
• Speedy characters have a fast run speed.
• Powerful characters have strong and fast shots.
• Defensive characters have a wide coverage.
• Tricky characters have more curve in their shots.

Post-release characters, with few exceptions, each have unique traits.

Mario is the only playable character for the majority of the Adventure mode (Peach is also playable in Lucien Cup Finals), and none of his variations available in other modes are usable. Players can, however, select from multiple rackets as they are unlocked in the mode.

Courts

Marina Stadium is the starting court, and other playable courts are unlocked for Free Play by completing levels in Adventure Mode. Like in Mario Power Tennis, some courts contain hazards that can be toggled on or off. Prior to version 2.2.0, a court selection screen for Free Play was absent, and courts are chosen at random (however Custom lets the player choose to set the selection of stages).

Story

In some ruins within the Kingdom of Bask, Wario and Waluigi stumble upon a tennis racket named Lucien. As they decide over who gets to use it, Lucien suddenly envelops them both in a mysterious light.^a

After Mario and Peach beat Bowser and Bowser Jr. in a tennis match and take the championship,^b Wario and Waluigi arrive with Lucien, offering it to Mario and co. as a present. After Luigi takes Lucien, Lucien possesses both him, Wario and Waluigi, and causes a big storm on the stadium. Mario and Toad go to Bask Ruins, and after beating a Dry Bones in a tennis match, gain entry to the Temple of Bask. There, a mysterious voice who introduces himself as Aster tells Mario that many years ago, Lucien destroyed the Kingdom of Bask, and its king managed to strip Lucien of its power and divided the power between five Power Stones. Over time, though, the room fell to ruin, and Wario and Waluigi stole Lucien oblivious to its true powers. Aster then tasks Mario to go and get the five Power Stones before Lucien does.

Mario manages to take the Power Stones from Piranha Plant Forest, Mirage Mansion, and Snowfall Mountain; however, the possessed Wario and Waluigi beat him to the Power Stones in Savage Sea and Inferno Island. Lucien then declares a tennis war at Marina Stadium that pits Peach and Daisy against Wario and Waluigi, and Mario against Luigi, which Team Mario wins. Bowser then steals Lucien and returns to the Temple of Bask, where he fuses into Bowcien and challenges Mario to one last battle. Mario wins, destroying Lucien as well as the temple and receiving thanks from Aster before he disintegrates. Everyone then celebrates Mario's victory (though Wario and Waluigi express shame for having to destroy Lucien) as the credits roll.

In a post-credits scene, Mario writes an autograph on the camera, with the marker squeaking the first seven notes of the Super Mario Bros. overworld theme.

Gameplay

The complete collection of rackets in their default order

In Adventure Mode, Mario has to travel in a hub world and complete missions. While some of them are regular tennis matches, Adventure Mode has a lot of other missions, such as challanges where Mario needs to return the ball until he gets a certain amount of points. It also features boss battles, where different objects need to be shot on bosses with the tennis racket to defeat them. Additionally, the level selection appears to be based on that of the New Super Mario Bros. games, with red panels indicating an unfinished level and blue panels indicating a completed level, with the name of the level being shown when Mario stands on one.

Throughout his journey, Mario can obtain rackets of different stats. All unlocked rackets are stored in a queue that can be viewed in the Stats menu. Each racket unlocked has better stats than the last and takes the front position in the queue. If one of Mario's rackets breaks during a mission, the next one in the queue will take its place until he has no more rackets, signifying that the mission has been lost. By default, these rackets are ordered from the strongest to the weakest (i.e. from the newest to the oldest unlocked), but the player can change their order in the Stats menu.

The following are Mario's rackets, with the mission where they are obtained mentioned under their name.

Co-op Challenges

In Co-op Challenges, four players cooperate to obtain a number of points in a limited amount of time. At the end of a challenge, the total amount of points earned by every participant is awarded to everyone. There are three goals during each Co-op Challenge event, which players can surpass to unlock alternate skins for a specific character. In addition, each point goal, including the 0-point mark, corresponds to a different title which the player can earn by surpassing that goal. For example, the player is a "Veteran Boo Hunter" if they complete the 2,500 point goal in Boo Hunt.

Boo Hunt

When Frenzy Time is activated, King Boo will appear.

Boo Hunt uses Swing Mode controls. In this event, players use tennis balls to hit Boos on the opposing side of the court to eliminate them, earning coins in the process. If the Boos reach the center of the court, they will steal some coins from the group total. Small mirrors that line the center of the court shoot tennis balls for the players to hit. Some Boos have an orange glow, and when a player hits them their next ball will be large, allowing them to hit more Boos at once. There are three stages, and when the group total reaches a certain threshold of coins they can proceed to the next stage when time runs out. Hitting Boos will also increase the Frenzy bar. When the Frenzy bar is filled up, Frenzy Time will activate. King Boo will appear and hover around the court, and all players will continuously receive tennis balls to hit him to earn more coins. He will disappear when either his health bar or the Frenzy bar is depleted.

Different stages have different hazards. Usually, the group of Boos slowly move towards the center of the court. In some stages, they assemble into set formations, and after the players hit the ball at them, they re-assemble into a new formation. Sometimes, the lights turn off, making it hard to see the Boos. Two glow-in-the-dark Boos also appear, and if a player hits one of them, they will be able to control their mirror to shine a light at the Boos that will halt them in their tracks. Other times, pieces of furniture will fly around the room, making it hard to hit the Boos, and Golden Mushrooms will appear, which can be hit to earn coins.

In version 2.1.0, Boo Hunt is permanently added to Special Games in Swing Mode.

Yoshi's Ring Shot

Yoshi's Ring Shot in the first event, held November-December 2018

Yoshi's Ring Shot uses traditional button controls. In this event, all four players must work together to reach a high score by hitting the tennis ball through the colored rings. Each ring has four different colors based on the colored Yoshis being playable in this challenge only. If a Yoshi hits the tennis ball through a ring of the same color, it receives more points by doing so. The player can also obtain more points by shooting a ball through multiple rings. The smaller the ring, the more points the player earns. When a Zone Shot or Special Shot is triggered, the player earns double/triple the amount of points. To increase the Frenzy bar, players must keep a rally to increase points and activate Frenzy Time once it is full. During Frenzy Time, all the rings turn into a rainbow color, which are worth more points. In the last 30 seconds of the clock, a special flower-shaped ring appears, which is also worth more points than regular-colored rings. Hitting the flower-shaped ring causes the ring to move to a different location each time, and by increasing combos, players can earn more points and fill up Frenzy bar faster.

In version 3.0.0, Yoshi's Ring Shot is permanently added to the new Ring Shot mode.

  Frenzy Time

Shy Guy Train Tussle

Once Frenzy Time is reached, several stacks of Shy Guys will appear in front of the players. The Shy Guy towers can be reduced progressively as more Shy Guys are defeated.

Shy Guy Train Tussle uses Swing Mode controls. In this event, players have to retrieve as many coins as possible from a band of Shy Guys who have stolen them and are trying to escape by train. To earn coins, players mut use snowballs to defeat Shy Guys (who are either on the train or around the train) or destroy the train's freight consisting of crates and barrels. Stationary cannons in the background shoot snowballs for players to hit. There are eight stages, and after the group total reaches a certain threshold of coins, they can proceed to the next stage when time runs out. Hitting Shy Guys will also increase the Frenzy bar. When the Frenzy bar is filled up, Frenzy Time will be activated once the current stage is cleared. Shy Guys will then jump in from the background, forming tall towers by stacking on top of each other, and all players will continuously receive snowballs to hit them to earn more coins. Defeating a tower of Shy Guys and destroying the crate on top of them grants players a key to opening one chest full of coins. Any remaining Shy Guys will leave once the Frenzy bar is depleted. Frenzy Time can be activated up to three times, and each time, one additional tower of Shy Guys is present for players to defeat.

Train layouts and Shy Guys tend to vary slightly between stages, constantly providing players with a different challenge when trying to collect coins. Shy Guys may come in singles or in stacks, as well as larger variants or shield-holding ones; the latter two variations require two hits to defeat them. Some Shy Guys float across the screen with the help of balloons and carry large amounts of coins in crates. Often, players will encounter different kinds of chests as part of the train's freight, which are opened on different conditions. For example, some chests require players to defeat a certain number and color of Shy Guys in order to open them, while other require players to uncover a key hidden inside of a crate.

Each stage also has a certain quota for players to achieve in order to earn extra coins. Once players fulfill a stage's quota, they will earn a large sum of coins which are added to the total threshold. Some crates hold large amounts of extra coins as well as power-ups such as Super Mushrooms, Ice Flowers, or Bob-ombs for players to use. The power-ups can be used to enhance the effect of their snowballs, with the Super Mushroom making the ball larger and able to destroy sturdier crates or barrels in one hit, the Ice Flower splitting the ball into four, and the Bob-omb being able to destroy a large portion of the train's freight.

A large Black Shy Guy appears as a boss in the fourth and eighth stages, wearing a yellow bandana in the former and a red bandana in the latter. Players must defeat him both times in order to successfully complete the Co-op Challenge. As players try to hit him with snowballs, he walks around while occasionally jumping to certain locations on or in front of the train. At one point, he throws Bob-ombs at each of the players which can be knocked back at him to deal more damage than usual. In the fourth stage, players simply have to deplete his entire health bar in order to defeat him. In the final stage, as they fully deplete his health bar, he initiates one final attack in which he throws a big Bob-omb that must be knocked back to him by all players in order to defeat him. Once he is defeated, he drops keys which unlock chests that completely fill the threshold of coins needed to complete the stage, thus signaling a successful end to the mission.

In version 3.1.0, Shy Guy Train Tussle is permanently added to Special Games in Swing Mode.

Demos

Pre-launch demo

Title screen

Prior to the game's release date, a free demo titled Mario Tennis Aces: Online Tournament Demo was released on the Nintendo eShop on May 24, 2018. This demo included a pre-launch online tournament, as well as the ability to practice with CPU players. The tournament allowed players to play as Mario, Peach, Yoshi, and Bowser, with Waluigi, Toad, Spike, Rosalina, and Chain Chomp becoming available as players earned points, for a total of nine playable characters. All tournament participants could receive an alternate costume for Mario that dresses him in his usual clothes (effectively making him appear identical to his appearance in Mario Tennis: Ultra Smash), usable in the full game.

Unlocking criteria for these participants
Waluigi	Earn 100 points in total.
Toad	Earn 300 points in total.
Spike	Earn 600 points in total.
Rosalina	Earn 1000 points in total.
Chain Chomp	Earn 1500 points in total.

Another free demo titled Mario Tennis Aces: Special Demo or Mario Tennis Aces: Special Online Demo was downloadable between April 26 and May 3, 2019, but only playable from April 26 to April 28, 2019. Upon downloading it, the player received a code for a free seven-day subscription to the Nintendo Switch Online service. Compared to the previous demo, this demo had some changes and additions. It featured a different title screen, different unlockable characters, simple class, Co-op Challenge mode (where Yoshi's Ring Shot was playable, and the blue, red, and yellow Yoshis could be unlocked for use in both the demo and the release version), and other features introduced in the full game as of version 2.3.0 (new adjustable control options and a revamped online tournament). The character unlock criteria was also changed, requiring the player to simply play a set number matches (including both computer and online matches) to unlock each character instead of earning points in tournaments. Likewise, Mario's alternate costume could be unlocked by participating in a match either online or offline.

Unlocking criteria for these participants
Waluigi	Play 3 matches in total.

Update history

Mario Tennis Aces has received multiple updates after launch, which added new content, character balancing, and bug fixes. Notable changes unlisted in the patch notes are written in italics.

1.1.0

An update was released on June 21, 2018 (PT). The following changes were made:

• Additional New Modes and Features
  • We have added “Online Tournament” to Tournament mode.
    • When playing Online Tournament, you can choose from four different types of courts in Marina Stadium.
    • We have changed the name of the tournament mode using computer partners to “COM Tournament.”
  • We have added “How to Play” to the main menu. You are now able to practice basic shots and new shots outside of the “How to Play” in Adventure mode.
  • We have added “Bonus” to Adventure mode. This allows you to play the story over again from the beginning and watch movies.
    • “Bonus” will be added once you have cleared Adventure mode once.
    • When you select “Start from Beginning,” your progress, level, and obtained rackets will all be reset. It is not possible to carry over your status and play from the beginning.
• Changes to Online Play
  • Online play: We have made some changes to the way that latency is handled in online play.
    • We have addressed an issue that caused severe latency when the network connection became unstable.
    • We have raised the frequency with which the game confirms and refreshes connection quality. This addresses the problem of connection quality remaining low for a longer period than necessary once the connection was determined to be poor in one single instance.
  • Online play: We have made some adjustments so that players of similar skill are more likely to be matched together. (Outside of matches with friends)
  • Online Tournament: We have improved the accuracy of processing the confirmation of connection quality for both yourself and your opponent before the start of a match.
  • Online Tournament: We have addressed an issue that caused a dropped connection at a certain time in a match to result in the dropped player receiving credit for a win.
  • Free Play: We have addressed an issue that caused the next match to automatically begin when no control input was detected after a certain amount of time at the end of an online match.
• Reading save data from the online tournament prior to launch
  • When you have save data from playing one or more matches in the online tournament that took place prior to launch, you will obtain Mario's “classic outfit.” You will be able to switch to this at the character select screen for each mode. You cannot change character appearance in Adventure mode.
• Asian Languages
  • We have added support for Chinese and Korean languages.
• Other
  • Overall: We have addressed an issue where a Zone Shot that landed very close to the line was being counted as out.
  • Standard Overall: We have addressed an issue that caused your Energy Gauge to fill on a Nice Serve even when the shot was a fault or a let.
    • The above two issues did not occur during the online tournament prior to launch.
  • COM Tournament: A crown mark will now appear next to the name of a character who has won the tournament.
  • COM Tournament, Online Tournament: Suspend data from a tournament will now include your settings choices from the character select screen.
  • Some changes from the online tournament prior to launch are also included.
  • When you update to version 1.1.0, you will no longer be able to engage in local play with those using version 1.0.0.
  • COM players will now correctly block Zone Shots from Piranhas in Piranha Plant Forest.

1.1.1

An update was released on June 28, 2018 (PT). The following changes were made:

• Changes to Online Tournaments
  • The “Rating” feature will be added to the game on July 1, 2018. Ratings scores will start at 2,000 and go up after scoring points and go down when losing points in matches. It is a score that shows how strong the player is. (The in-game ranking board will continue to be based on Total Points.)
  • In cases where there is a disconnection during a match, ratings will go up or down based on the score in that match at that time.
  • When there is great discrepancy between players in ability, a player’s rating may not go up even if they win.
• Changes to missions in Adventure mode
  • Forest Practice Court: We have adjusted how often the opponent uses Zone Shots.
  • Forest Edge: We have adjusted how quickly the opponent responds to shots.
  • Reflection Room: We have adjusted how much Energy is refilled.

  • There will be further adjustments to game balance in matches and character performance.

1.1.2

An update was released on July 19, 2018 (PT). The following changes were made:

• Game Balance Updates
  • For All Characters:
    • We have adjusted the range within which a character is able to return a ball, as well as how much energy is used when doing a Trick Shot to hit a ball that goes behind them.
      • *We made the distance you can move and the scope between left and right shorter. We also shortened the time it takes to successfully recover energy and increased how much energy is used when a Trick Shot is late.
    • We have made it so that, when returning a serve, a ball cannot inflict a Body Shot until it bounces once.
  • For Bowser Jr.:
    • We have adjusted how fast Bowser Jr. can move when charging a shot and lowered the angle at which he hits the ball back.
      • *We plan to adjust the balance of this character further in time for the August tournament
• Other Changes
  • Revised errors with text display.
• Notice about the Rating system in Online Tournament
  • A ranking display based on Rating will be added to the ranking board starting with the August 2018 tournament. Along with this change, the Rating will not be shown on the Total Points Ranking board. If you want to check your Ratings for July, please check the Tournament chart.
  • Your Rating will change on a monthly basis based on the results of the previous month's play. (This will be reflected starting with the switch from July to August.)
    • *Ratings of 2,000 or less -> Start at 2,000
    • *Ratings from 2,000-2,500 -> Same rating will be maintained
    • *Rating of 2,500 or more -> 1/10 of the value will be added to 2,500
    • *Value will be reset to 2,000 if the player did not play the previous month or if any questionable data is present.

1.2.0

An update was released on July 31, 2018 (PT). The following changes were made:

• Game Balance Updates
  • We have increased the minimum energy level used for a Zone Shot serve from 25% to 30%. 33% energy is still needed in order to trigger the shot.*
  • We have shortened the distance a character is pushed back when returning a shot that pushes the opponent to the back of the court, such as a Max Charge Shot.
    • The player can reduce the impact of being pushed back by returning a Topspin and Lob with a Slice, a Slice with a Topspin, and a Flat with a Flat.

• New Mode “Ring Shot”

  • This includes three game modes: Ring Shot Singles, Ring Shot Doubles, and Yoshi's Ring Shot, which can be played by up to four people on one Nintendo Switch console at the same time. Each game mode features a co-op mode that allows you to cooperate with another player to maintain a rally as you aim for a high score. They also include Beginner Co-op Challenge through Advanced Co-op Challenge, in which you compete for a high score by hitting more balls through rings than your opponent in order to clear the level.
  • Ring Shot Singles and Ring Shot Doubles can be played on all courts with hazards. Furthermore, hazard effects have been added to ring-shot gameplay to create a wider variety of ways to play.
  • When you clear Advanced VS Challenge in Yoshi’s Ring Shot, you can get a purple Yoshi to use in regular matches. This is the only way to get this purple Yoshi.
• Co-op Challenge: Yoshi’s Ring Shot
  • This Co-op Challenge will be available again from the distribution of Ver. 3.0.0 until 9:00 AM on June 1, 2019. Co-op Challenge is a mode for online play available only for a certain period of time.
    • Nintendo Switch Online membership is required to play Co-op Challenge.

  • A four-player team is formed among friends or players online to achieve an objective together.
    • If each player has a controller, up to four players can play on a single Nintendo Switch console.

  • When playing with two or more players in Free Play or Swing Mode, you can now choose the option Service (which side will serve first). You can choose from Random, P1 Side Serves, or P1 Side Receives whether you’re playing in Singles or Doubles.
    • However, this setting is only possible when people are playing against each other. A team with two COM players will always start receiving. When only one person is playing, the Service settings menu will not appear.
  • Before character selection in Free Play or Swing Mode, you can now select the same character as your opponent when your doubles partner has been decided. This is under Doubles Partner when selecting P1 and P2, or when selecting Team in Local Play and Online Play.
    • In a future update, we plan to add a “Select every time” menu option for Doubles Partners, so that you can select the same character as your opponent when your partner has been decided even before character selection.
• Adjustments to the Shot System

    • The player who is not showing the motion effect can still recover half of their energy by successfully completing a block without using Zone Speed.

Reception

Critical reception

Mario Tennis Aces received generally positive reviews from critics. Praise was directed at the visuals and many welcomed new additions of gameplay, but minor criticism was directed at customization and the story mode, with some considering the latter not being rewarding or satisfying enough. The Swing Mode also received mixed reception, with points of contention directed at its responsiveness. The game currently holds a score of 75 on Metacritic based on 84 reviews, and a score of 73.38% on GameRankings based on 37 reviews.

Tristan Ogilvie of IGN gave the game a score of 7.5/10, praising the visuals, the court gimmicks, and the multiplayer mode, but criticized the story mode (considering it bare-bones, with nothing making it a fresh and satisfying experience), and also criticized the way local multiplayer works, stating "The biggest problem with Mario Tennis Aces'[s] Adventure mode is how poorly it incentivises you to keep playing. I had completed all 27 of its levels and unlocked all of its courts and rackets by the time I was on level 34, which was around a half a dozen hours of game time. Out of curiosity, I replayed a number of the challenges and boss fights several more times over to grind my way up to level 55, but was rewarded with absolutely nothing aside from incremental boosts to Mario's stats, thus making the existing challenges even easier. With no New Game+ or more challenging versions of its levels to unlock, or even the option of playing through it with a different character, Mario Tennis Aces'[s] Adventure mode becomes increasingly simple and repetitive the more time you put into it." In a more positive review, Mike Diver of Nintendo Life gave the game an 8/10, praising what he believed to be vast improvements over its Wii U predecessor Mario Tennis: Ultra Smash, stating "Where [Mario Tennis:] Ultra Smash's extras were a pure Monkey Island's worth of living without that particular piece of junk – here's your context, kids – [Mario Tennis] Aces stuffs its kit bag with activities until the zip's positively pinging off across the locker room like a smartly volleyed can of energy drink. Not everything is evenly fleshed out, but whatever your preferential way to play, there's plenty to get stuck into, both solo and with pals." In a slightly more lukewarm review, Justin Clark of GameSpot gave the game an 7/10, praising the game's new playing mechanics over past games as well as the story mode's incentive to teach players of the new mechanics, but had mixed to somewhat positive feelings about the story mode, stating "The story itself is ridiculous, but ridiculous in that very specific, quirky way Nintendo has been getting away with for decades. During the Mushroom Kingdom's annual tennis tournament, an evil tennis racket--yes, really--named Lucien takes possession of Luigi and flies off to find five Power Stones that will help him take over the world." He was also more critical of the online play, panning a stark lack of features as his main issue.

Reviews
Release	Reviewer, Publication	Score	Comment
Nintendo Switch	Tristan Ogilvie, IGN	7.5/10	"Despite some single-player shortcomings, Mario Tennis Aces is still a lot of frantic tennis fun with friends."
Nintendo Switch	Mike Diver, Nintendo Life	8/10	"We're used to seeing Wii U games transfer to Switch, but for Ultra Smash to have moved across without a substantial makeover would have been disastrous. Aces, wonderfully, is anything but that – it's a superb arcade sports game that's generous with its suite of player options and only occasionally guilty of being a little cheap in its Adventure Mode. The presentation is spot on, and the core tennis action is absorbing whether you're trading simple strokes or firing off special shots. Some animations and voice overs are identical to Ultra Smash's, but everything around them has been overhauled to quite splendid heights. This is something of a Switch Port Plus, then – not quite a whole new experience, but so improved as to be near unrecognisable next to its preceding title."
Nintendo Switch	Justin Clark, GameSpot	7/10	"It speaks volumes that even the multiplayer limitations don't entirely dampen my enthusiasm for Aces. The Tetris Effect is in full swing here; days after the credits rolled, I still crave the satisfying thwack from a Power Shot, mentally replay matches and imagine how I might do things differently given a bit more focus and know-how. Mario Tennis Aces does what this series has done best, and for the most part, improves what it's rarely gotten right prior."

Daisy's pose in the final game

The Special Chance Shot markers from Mario Tennis: Ultra Smash, needed to perform the Ultra Smash, were featured in the announcement trailer. The animation Mario performed there was also the same one used for those kinds of shots. In the final game, however, those Chance Shot markers were rather replaced with a rotating star marker, similar to the ones featured in Mario Tennis and Mario Power Tennis, and Zone Shots replaced Ultra Smashes, while retaining their character animations at least in the case of Mario.

The HUD icons for Mario, Luigi, Wario, and Waluigi originally used their traditional outfit. Various pre-release footage of Marina Stadium had different cosmetic screen animations in banners, and the character name in the court's floor had a different font (this font is used in the final game when playing in online modes, with the user nickname on the floor). The Ancient Altar court used in Forest Monster was originally a selectable court.

Originally, Daisy's final entrance pose showcased her with her mouth closed via a Nintendo Treehouse Log post. In the final game, her mouth is open.

Trivia

• In 2018, a browser game based on the game was released on the Play Nintendo website called Mario Tennis Aces Fun Trivia Quiz.
• Starting with this game, Simplified Chinese names of many common enemies were overwritten with their Traditional Chinese counterparts, like Koopa Troopa (喏库喏库 to 慢慢龟), Boo (嘘嘘鬼 to 害羞幽灵), Dry Bones (枯骨怪 to 碎碎龟), and Lakitu (朱盖木 to 球盖姆). However, Simplified Chinese names of major characters (Mario, Princess Peach, Bowser, etc.) and Shy Guy remained unchanged. Common enemies whose names did not appear in this game would witness their name change in the coming Super Mario Party, with Hammer Bro (锤子兄弟 to 铁锤兄弟) as an example.
