Mario Tennis Fever brings a new set of abilities to the familiar arcade-style tennis formula. Coming to Nintendo Switch 2, the latest entry adds modes, characters, rackets, and mechanics while keeping the sport’s core rallies at the center of play. Its main new feature is a collection of special rackets that can change what happens on court.

What is new in Mario Tennis Fever?
The word “Fever” refers to the game’s Fever Rackets. There are 30 in total, and each one has a distinct ability. Players build up the power for a Fever Shot through rallies, then use the shot during a match to activate that racket’s effect.
These abilities can affect the court or the players in different ways. The Ice Racket, for example, freezes the court and makes its surface slippery. Other effects can shrink opponents or create a duplicate of the player. With a range of abilities available, choosing a racket can influence how a rally unfolds.
How Fever Rackets can shape a match
Because Fever Shots are charged through rallies, keeping the ball in play is an important part of using this feature. Players may want to think about when to activate a shot rather than treating it as an automatic move. An effect that changes the court could make positioning more challenging, so staying ready to adjust is useful once a Fever Shot is deployed.
- Build through rallies: The game charges Fever Rackets as rallies continue.
- Expect varied effects: Rackets can alter the court or affect player size and presence.
- Stay adaptable: A changed surface, such as the slippery court created by the Ice Racket, may call for adjustments during play.
A familiar tennis foundation with new options
The Mario Tennis series has appeared on Nintendo platforms over multiple generations, much like Mario Kart. Mario Tennis Fever does not discard the basics of the sport; instead, it layers new features onto the established tennis setup. The game also expands its offering with additional modes, characters, rackets, and mechanics.
Tennis has a long history in video games, dating back to Tennis for Two in 1958. That connection helps explain why the sport remains a natural fit for accessible, competitive play. A straightforward rally can be easy to understand, while character abilities and special equipment add variety for players looking for more ways to approach a match.
What to keep in mind
Players interested in the new system should pay attention to both the rally and the racket effect they choose. Fever Rackets add an extra decision to the match, but the source details do not specify every racket’s ability or explain the full rules for each mode. More specific strategies will depend on those individual effects and how they work in play.
Overall, Mario Tennis Fever combines familiar tennis gameplay with a broad selection of court-changing abilities. Its 30 Fever Rackets give players new effects to explore, while rallies remain the way to charge Fever Shots. For anyone following the series on Switch 2, that blend of recognizable fundamentals and added match variety is the central feature to watch.
