Mario Tennis Fever Gets New Update for March 2026

by

A new update for Mario Tennis Fever focuses on making the game more balanced. Version 1.0.2 adjusts the power levels of characters and rackets, and slightly changes how shots work in matches. The goal is to ensure all characters are fairly balanced and have their own unique way of playing.

Nintendo’s first game designed specifically for the upcoming Switch 2, Mario Tennis Fever, has been doing well since its February 12th release. Players and critics have generally given it positive reviews, and it’s been welcomed by fans who have been waiting almost eight years for a new Mario Tennis game after Mario Tennis Aces on the original Switch. The game’s success is partly due to players’ fondness for the series, but also thanks to its fun, over-the-top special moves and the large selection of nearly 40 playable characters from the Mario universe.

Recent updates to Mario Tennis Fever focus on how reliably characters can hit the ball with precision, and how close they need to be to do so. Baby Peach, Dry Bones, Shy Guy, and Toad can now hit stable shots from a bit farther away. On the other hand, Donkey Kong, Petey Piranha, Rosalina, and Wiggler have had their ability to hit stable shots from long distances slightly reduced.

So, the new update tweaked a couple of characters. I noticed Petey Piranha and Donkey Kong feel a little slower to get going – it takes a bit longer for them to reach full speed after I start moving them. Honestly, Donkey Kong got hit the hardest with this patch; he’s the only one with three changes! They also adjusted how his movements register hits when I’m moving him side to side. And finally, Diddy Kong’s shots and serves are a little stronger, though the update doesn’t say by how much. It’s a small boost, but every little bit helps!

Several of the special rackets in Mario Tennis Fever have been adjusted for better balance. Most of these changes reduce how long the rackets’ unique abilities last. The Metal and Star rackets now have effects that last two seconds less, while the Magic and Ghost rackets have a three-second reduction. The Golden Dash Racket sees the biggest change, with its effect duration shortened from 12 to 8 seconds. As a trade-off, the Metal and Star rackets can now deflect Spinies during their active period, and the Ghost Racket gives players an extra half-second to preview shot paths when hitting lobs. Finally, the Inky Racket’s screen-obscuring effect now appears twice as fast after the initial hit.

Besides the changes for specific characters and rackets, we’ve made some general improvements to Mario Tennis Fever, including bug fixes and a gameplay adjustment that will impact most matches. Previously, quickly tapping the shot button twice to cancel a charged shot caused your character to jump or slide. We’ve removed this animation to give players more precise control. This change won’t apply during multiball matches, which will play as they did after the 1.0.1 update.
