Mario Tennis Fever is a multiplayer sports game in the Mario Tennis series released worldwide for the Nintendo Switch 2 on February 12, 2026 as part of the Super Mario Bros. 40th Anniversary celebration. It is the ninth installment in the Mario Tennis series, and the first Mario sports game to be released on the Nintendo Switch 2. The gameplay elements are similar to those of Mario Tennis Aces, but the game introduces new features, including Fever Rackets. Each Fever Racket has its own special abilities, creating unique effects on the court. Players can build up their Fever Gauge during rallies, allowing them to use new tactics with Fever Shots. The game incorporates elements from Super Mario Bros. Wonder in modes such as the Tournament and Mix It Up.

Additionally, the game features a story mode in which Mario and others are transformed into babies by monsters encountered on a remote island. Having lost their tennis skills, the babies must learn to play tennis from scratch and defeat the monsters to return to their original forms.

The game was first revealed on the Nintendo Direct which aired on September 12, 2025. An overview trailer for the game was released on January 8, 2026.

Gameplay

Mario Tennis Fever retains the basic tennis gameplay of the Mario Tennis series. New to the series are character HP and the Fever gauge. As players continue to rally the ball, their Fever gauge will fill. When full, players can activate their Fever Racket to hit a special Fever Shot, which has a special effect based on the player's racket. However, if the opponent manages to hit the Fever Shot back before it touches the ground, the Fever Shot will not yet be active and can even take effect on the user's side of the field. During gameplay, characters can lose HP when taking damage from obstacles. Upon losing all their HP, characters will either lose movement speed in singles or be knocked out in doubles, requiring time to recover before they can rejoin the match. Additionally, in doubles, teammates can time their shot to hit a Fever Shot together at the same time. Due to the presence of obstacles on the court from Fever Rackets, the traditional court change between sets does not occur when Fever Rackets are on.

Swing mode also returns from Mario Tennis Aces, allowing players to control their racket by swinging a Joy-Con 2 controller.

Types of shots

Shot		Description
Topspin		Stronger, red-trailed shots that bounce.
Slice		Weaker, blue-trailed shots that curve more.
Lob		Yellow-trailed shots that fly in a high arc.
Flat		Purple-trailed shots that travel straight and are the fastest shot.
Drop Shot		White-trailed shots that are weak, hit close to the net, and do not bounce much.

Game modes

Adventure

The Mushroom Tennis Academy

The Adventure mode is a single player mode centered around a story where Mario and his friends, with the help of Wario and Waluigi, travel to a mysterious island to find a golden fruit that can heal Daisy from her sickness. Mario, Luigi, Peach, Wario and Waluigi are cursed and turned into babies, losing all their tennis skills in the process.

The player controls Baby Mario and Baby Luigi as they train at the Mushroom Tennis Academy, learning the basics of playing the game through various minigames. Later, they return to explore the mysterious island in order to find a way to turn Baby Mario, Baby Luigi, Baby Peach, Baby Wario and Baby Waluigi back to normal. They must then beat various challenges and defeat bosses along the way.

Tournament

Tournament mode allows players to participate in three tournament cups made up of eight-player bracket, featuring commentary from a red Talking Flower. Initially, only the Mushroom Cup is available, while the Flower Cup and Star Cup are unlocked by clearing the preceding cup. This is also the first Mario Tennis game where unlockable characters can appear as opponents in the tournament bracket.

Cup	Court	Rules
Mushroom Cup	Grass Court	Round 1: 1 set of 2 games Semifinals: 1 set of 2 games Finals: 1 set of 2 games
Flower Cup	Clay Court	Round 1: 1 set of 2 games Semifinals: 3 sets of 2 games Finals: 3 sets of 2 games
Star Cup	Hard Court	Round 1: 3 sets of 2 games Semifinals: 3 sets of 2 games Finals: 5 sets of 2 games

Trial Towers

Trial Towers mode features three towers made up of ten challenges each. Characters, rackets and rules are predetermined for each challenges. In each tower, the player starts with three hearts. If they fail a trial, they lose a heart and are forced to re-do it. Losing all hearts causes them to re-do the entire tower from the start. Beating one tower unlocks the next one. After beating all three towers, 100 new, individual trials, are unlocked, with each trial having three objectives. A second player can join as a shadow character.

Free Play

Free Play mode allows players to create custom matches by changing a variety of rules. Players can pick between singles and doubles, choose to use one, two, or no Fever Rackets, and set the match length between quick play (first to seven points wins, like in a tiebreaker), extended play (two-game, one-set match), or custom length (players can select one, three, or five games per set, two, four, or six sets, and with or without tiebreaker). Then, players select the court, along with the ball speed and camera angle, followed by the characters and rackets.

Mix It Up

Mix It Up mode contains a variety of unconventional game modes with special rules, items and obstacles appearing on the court.

Special Matches

In Special Matches, matches with unique rules or obstacles can be played.

Game mode	Player amount	Description
Ring Shot	1-4	In the returning Ring Shot mode, players either compete or cooperate to pass the ball through various rings that continuously spawn over the net within a time limit. Hitting multiple rings at once grants a multiplier bonus, and rallying a Fever Shot through rings without letting it touch the ground provides a larger multiplier (up to 5x).
Forest Court Match	1-4	In a Forest Court Match, played only on the Forest Court the court is divided into sixteen squares, eight on either side. Squares filled with grass are considered inside the court, while squares that only have dirt are considered out. Players compete against each other, attempting to feed balls to Piranha Plants on their opponent's side of the court. This causes a square on the opponent's side to grow grass, becoming part of their court and increasing the area they have to defend. Grass squares fade away over time.
Pinball Match	1-4	In a Pinball Match, which takes place on the Waluigi Pinball Court, various effects can be triggered on the court, such as bumpers appearing on one side, Flippers appearing to protect a player's baseline, or extra balls in play.
Racket Factory Match	1-4	In a Racket Factory Match, taking place on the eponymous Racket Factory, the court is divided into quadrants on either side. A cannon in the background periodically launches Fever Rackets into random quadrants during play, allowing players to change their rackets mid-game.
Wonder Court Match	1-4	A match taking place in the Wonder Court, with Wonder Effects which can be triggered by hitting Wonder Flowers with the ball. Effects include Trottin' Piranha Plants appearing on the net, various Hoppos bouncing around the court, or Spikes throwing colored Spike Balls into the court. Wonder Seeds can be collected during Wonder Effects as well.

Score Challenges

in Score Challenges, players try to reach specific amounts of points in various challenges with special rules.

Game mode	Player amount	Description
2P Co-op Ring Shot	1-2	A cooperative singles version of the Ring Shot where both sides work together to achieve a score goal.
4P Co-op Ring Shot	1-4	A cooperative doubles version of the Ring Shot where both sides work together to achieve a score goal.
Piranha Plant Challenge	1	The returning Piranha Plant Challenge mode from Mario Tennis. The player must hit balls shot randomly from three Piranha Plants without letting their opponent return it in order to reach a score goal.
Auto Tennis	1	A special game where the player must return a ball shot from a Piranha Plant robot in order to hit panels on the floor and score enough points. Panels can give different amounts of points, and the robot can occasionally shoot Fever Shots. Like in Galaxy Rally and Gooper Blooper Volley from previous Mario Tennis games, the number of panels that the ball can hit will decrease over time.

Swing Mode

In Swing Mode, players play matches with the option of using the Joy-Con 2 or Joy-Con motion controls. The only Fever Rackets available in this mode are the Personal Racket, Shadow Racket, Ghost Racket, Bullet Bill Racket, Inky Racket and the Boomerang Racket, the last of which is exclusive to this mode.

Playable characters

The game has 38 playable characters, tied with Mario Tennis: Power Tour for the most of any game in the series, of which 18 are available from the start, while the other 20 must be unlocked. Wiggler appears as a playable character for the first time since Mario Power Tennis, and Baby Mario and Baby Peach are playable for the first time since Mario Tennis Open, with Baby Peach also being playable for the first time in a home console installment.

Six characters make their playable debut in the Mario Tennis series in this game, those being Nabbit, Goomba, Piranha Plant, Baby Luigi, Baby Wario, and Baby Waluigi, with the game also marking Baby Luigi and Nabbit's debut in the Mario Tennis series (excluding the former's cameoMedia:MarLulOpening.PNG in the intro cutscene for Mario Power Tennis and being playable in the Tennis mode in Mario Sports Superstars), Baby Wario's first appearance in a home console game, and Baby Waluigi's first appearance overall. In addition, there are color variations for some characters and as in the previous game Mario Tennis Aces, the variations do not have their own distinct characters; for example, the Blue Yoshi is simply called Yoshi. Furthermore, Lumalee makes its playable debut, but is also a color variation of Luma. Including the color variations, this makes a total of 58 playable characters.

Playable characters are once again classified with a playing type, and four stats are now visible: Speed, Power, Control, and Spin. Each stat is rated out of five.

Adventure

Story

Mario, Luigi, Peach, Wario, and Waluigi after being transformed into babies, with Donkey Kong present

After Daisy has fallen ill and her health has not improved despite much rest, Wario and Waluigi inform Mario, Luigi, Peach, Toad, and Donkey Kong of a magic golden fruit found on a remote island with the power to cure her illness in time for the Mushroom Kingdom Tennis Tournament. The group travels by Peach's airship to the island, but upon arrival, Wario and Waluigi reveal their true intention of reaching the island: to find treasure from the ruins inside the tree growing the fruit. After Mario picks the fruit, Wario and Waluigi run out of the ruins in a panic while being chased by a horde of Fuzzies and a mysterious, dark cloud. While the group fights off the horde, the cloud transforms Mario, Luigi, Wario, Waluigi, and Peach into babies, causing them to lose their tennis skills in the process.

The group returns to the Mushroom Kingdom, where Baby Mario, Baby Luigi, Baby Wario and Baby Waluigi join the Mushroom Tennis Academy to learn how to play tennis again through various activities. Once ready, they return to the island to find a way to turn back. While on their airship on the way there, Baby Wario and Baby Waluigi challenge Baby Mario and Baby Luigi to a match, and end up setting various parts of the ship on fire with their Flame Rackets. The two escape via parachutes, and Baby Mario and Baby Luigi have to put out the fires with water bubbles.

Baby Wario and Baby Waluigi land on Bowser's Airship, having allied with Bowser to use his minions to clear the way on the island. Bowser wants to restore Baby Peach back to normal so she will fall in love with him. Baby Mario's airship ends up intercepted by Bowser's, who launches a Bullet Bill attack on them. Afterwards, the player unlocks the Flame Racket for use in the mode.

Baby Mario's airship crash lands at the Waterfall Basin, where the Toads find a passage to the Ice Ruins under a waterfall. There, they fight Ty-foos to clear the way to the area's boss: A Flame Chomp who consumed an Ice Racket and became the Ice Chomp. After defeating it and claiming its racket, the crew is rescued by Donkey Kong.

The Ice Ruins lead to the Limestone Cave, where Cheep Cheeps and a giant Cheep Chomp attack them. While traveling up the river found in the cave, a bigger Cheep Chomp eats the Lightning Racket, becoming the Lightning Cheep Chomp, the area's boss. Baby Mario and Donkey Kong defeat the boss, claim the racket and then find a way out of the cave.

At the Heavy Forest, they battle Piranha Plants and Piranha Creepers blocking the way forward, meeting with Daisy along the way. She helps Baby Mario fight the area's boss: Petey Piranha and its Mud Racket. After defeating Baby Wario and Baby Waluigi in a surprise match, Baby Mario gets the Ty-Foo Racket.

After the forest, they arrive at the Foggy Swamp, where Baby Mario and Baby Luigi fight a group of Stone Spikes and Hisstocrats to create a path for their raft to pass through. Finally, they battle King Hisstocrat, the area's boss. They then find Bowser's airship and meet with Baby Peach, who was forced to come along with him to the island.

At the Valley of the Monsters, Baby Mario defeats several Fuzzy Hordes, Brolders and Scuttlebugs to clear the mysterious fog on the way. It is revealed that the monsters who transformed them are Scuttlebugs powered by the magic tree and transformed into Heavy Scuttlebugs. After defeating two of them, Baby Luigi and Baby Peach return to normal. Baby Mario and Luigi then battle Bowser and King Scuttlebug, who, when defeated, transforms back into a regular Scuttlebug. Baby Mario then returns to normal, and everyone returns to the Mushroom Kingdom in Daisy's airship.

Reception

Mario Tennis Fever has received generally positive reviews from critics. Praise was directed at the amount of content, such as the character roster and Fever Rackets, while criticism was targeted at its single-player content, particularly the Adventure mode and its length, and its price point. It is the overall best-received game in the Mario Tennis series since Mario Power Tennis, with a score of 77 on Metacritic based on 76 reviews, and a score of 76 on OpenCritic based on 50 reviews.

Oli Welsh of Polygon noted that Mario Tennis Fever combined ideas from previous sports games in the franchise to stand out from real-world tennis. They thought the Fever Rackets were a "spectacular" take on the "gimmicky arcade mechanics" of Mario Tennis Aces and Mario Golf: Super Rush, while the Adventure mode is "more fleshed out than some recent examples, but it still feels like a clumsy obligation living in the long shadow of the GBA classics". Connor Christie of Pocket Tactics, while doubtful of the game before its release, ultimately felt it was a return to form for the series. He praised its unreliance on "multiplayer matches to extend your playtime, and making the Fever racket,^[sic] rather than the characters themselves, the star of the show", and concluded that it made him excited for Super Mario sports games in the future. Rachel Samples of Destructoid called the game a "chaotic, addictive serve that mostly sticks the landing" with enough characters and rackets to "keep the gameplay fresh", all with "gorgeous backdrops" and characters that are "full of life". However, she also thought that the racket effects could be distracting and that the Mushroom Academy, which functions as a tutorial, took up too much of the Adventure mode.

Reviews
Reviewer, Publication	Score	Comment
Logan Plant, IGN	7/10	"Mario Tennis Fever is a ton of fun with friends thanks to its wacky new abilities and huge character roster, but it’s once again let down by a bland Adventure mode that’s little more than an extended tutorial."
Steve Watts, GameSpot	8/10	"Mario Tennis Fever is the best Mario sports game in years thanks to the fun and flexible new Fever rackets that imbue the game with wild, game-changing effects."
PJ O'Reilly, Nintendo Life	8/10	"Mario Tennis Fever serves up my favourite game in the series thus far, by finding an addictive balance between Mario's madcap antics and real-world tennis fun. Streamlining superpowers into Fever rackets makes everything easier to parse, and keeping player movement relatively restrained makes for tennis matches that retain an exciting flow without constant slo-mo interruptions."
Brian Shea, Game Informer	7.5/10	"Mario Tennis Fever is hardly a revolutionary entry, but it nails the series' [sic] most important element by offering a well-rounded experience with myriad ways for players of all skill levels to enjoy the game of tennis."
Jordan Minor, PCMag	9/10	"Mario Tennis Fever is a must-have arcade sports game that wowed me by blending traditional techniques, power-ups, and fantastic, fighting game-like movesets."
Chris Scullion, Video Games Chronicle	6/10	"Mario Tennis Fever is another solid enough sports game from Camelot, but a disappointingly short single-player offering and a real risk of imbalance – whether using Fever Rackets or not – means what could have been fantastic will have to settle for simply being good."
Game Central	8/10	"The best Mario Tennis game since the N64 era and a hugely enjoyable multiplayer game with a ton of single-player content, although there’ll still be too many gimmicks for some people."
