IT House News on January 9th, technology media Wccftech published a blog post yesterday (January 8th), reporting that Nintendo released “Mario Tennis Fever” (Mario Tennis Fever).The initial release includes 38 playable characters, a record high, and will be exclusively available on the Nintendo Switch 2 platform on February 12, 2026.
Nintendo officially calls “Mario Tennis Mania” the “most substantial content in the history of the series”. The game provides 38 playable characters at the launch, which is far larger than any previous generation of the series and aims to provide players with the richest choices.



In the official warm-up video, the core mechanism of “Fever Rackets” was highlighted. The game contains 30 Fever Rackets with different attributes, each with unique special abilities.
Players need to accumulate energy through continuous pulling to unlock usage opportunities. Once activated, players can disrupt their opponents by freezing the field, releasing elemental damage such as fire or electricity, and even set up obstacles on the opponent’s field. This mechanism completely changes the rhythm of the game, making the originally simple tennis competition full of variables and chaotic fun.

In order to meet the needs of different players, the game provides a variety of battle modes. For players who prefer a traditional experience, “Classic Mode” removes all frenetic racket special effects and restores the purest tennis competition, ensuring that the outcome of the game depends on technology rather than random interference.
Instead, players who like a bit of fun can try a special mode inspired by Super Mario Bros. Surprise, where hitting a “Surprise Flower” triggers drastic changes in the field. In addition, the game also includes an “Adventure Mode” to guide beginners, as well as an online multiplayer mode that supports casual and ranked matches.
