Mario Tennis Fever is an upcoming multiplayer sports game in the Mario Tennis series set to be released worldwide for the Nintendo Switch 2 on February 12, 2026 as part of the Super Mario Bros. 40th Anniversary celebration. First announced during the September 2025 Nintendo Direct, 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 will incorporate elements from Super Mario Bros. Wonder in modes such as the Tournament and Mix It Up.

Additionally, the game will feature 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 will also offer expanded online feature modes.

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 Fever 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 player'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.

Swing mode also returns from Mario Tennis Aces, allowing players to control their racket by swinging a Joy-Con 2 controller.[12]

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

Free Match

Free Match[Japanese][3] 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 match length.[12]

Tournament

Tournament mode allows players to participate in tournament cups made up of an eight-player bracket, featuring commentary from a red Talking Flower.[12]

Trial Towers

Trial Towers mode features many various towers made up of different challenges. Characters, rackets and rules can all change between challenges. Beating one tower unlocks the next one.[12][3]

Mix It Up

Mix It Up[13] mode contains a variety of unconventional game modes with special rules, items and obstacles appearing on the court.[12]

Ring Shot
Main article: Ring Shot

In the returning Ring Shot mode, players either compete or cooperate to pass the ball through various rings that continously spawn over the net within a time limit. Hitting multiple rings at once grants a multiplier bonus.[12][3]

Forest Court Match

In a Forest Court Match, the court is divided in 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.[12]

Pinball Match

In a Pinball Match, 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.[12]

Racket Factory Match

In a Racket Factory Match, 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.[12]

Wonder Court Match

In a Wonder Court Match, Wonder Effects 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.[12]

Adventure mode

For further information, see § Adventure mode

The Adventure mode is centered around a story where Mario and friends have been transformed into babies and must relearn how to play tennis. Playing as Baby Mario, Baby Luigi, Baby Peach, Baby Wario and Baby Waluigi, players can learn the basics of playing the game, including the various types of shots they can perform, by taking on bosses and complete challenges.[12]

Playable characters

The game is confirmed to have 38 playable characters, tied with Mario Tennis: Power Tour for the most of any game in the series.[1] 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. New playable characters to the Mario Tennis series include 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 cameo 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.[12]

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.[12]
