Nintendo has just released the patch notes for Mario Tennis Fever‘s July 2026 update. This latest Mario Tennis Fever update is available now, giving all players access to an assortment of new Super Mario Galaxy-themed content, new GameShare functionality, and a bevy of character and racket mechanical tweaks.

Mario Tennis Fever is the 8th mainline entry in the Super Mario sports sub-series, and generally speaking, it was met with a warm reception from critics and fans alike. On OpenCritic, Mario Tennis Fever received a Top Critic Average of 77 and a recommendation rate of 76%. Since launch, Mario Tennis Fever has received three updates (including this most recent one), with the first two strictly focused on character balancing and performance improvements.

Mario Tennis Fever Adds Free Mario Galaxy-Themed Content

On July 15, Mario Tennis Fever received a brand new ‘Black Hole’ racket. When unleashing a Fever Shot, this racket causes a black hole to appear which pulls in nearby players and slowly reduces their health. If the player’s health falls to 0, they’re sucked into the black hole and are knocked out.

A new ”Galaxy’ court has also been added to Mario Tennis Fever. Directly inspired by Super Mario Galaxy (according to Nintendo’s patch notes), this new court sees players travel to a distant planet where balls are a little bouncier. To accompany this new court, Mario Tennis Fever has introduced a new ‘Galaxy Court Match’ mode, where three types of ‘Prankster Comets’ will appear and affect the usual flow of gameplay. One final piece of Mario Galaxy-themed content added in this latest Mario Tennis Fever update is five new colors for the Luma. Players can also now unlock a classic Mario outfit by obtaining five medals.

This most recent Mario Tennis Fever update has also added new GameChat and GameShare functionality. Players who own a copy of Mario Tennis Fever can now play the game with friends who don’t own it via GameChat. These GameChat play sessions can use either swing controls or button controls. It should be noted that all participating players need to have an active Nintendo Switch Online subscription to use GameChat and thus play Mario Tennis Fever via this method.

A total of 16 playable Mario Tennis Fever characters have been tweaked in this update. These changes range from an increased ability to aim for the sidelines for Pauline and Bowser Jr., to increased vertical reach for Luigi and Baby Luigi, to more extensive tweaks for characters like Dry Bones, who has received several sizable buffs. Eight of Mario Tennis Fever‘s rackets have also had their specifications tweaked, though the fan-favorite Ghost Racket is safe from any changes. An array of other minor changes have also been brought with this latest update, including the ability to select “Random” on the racket selection screen and behind-the-scenes adjustments on how modes are randomly selected when the player selects “Search All Modes” in ranked play.
