Mario Tennis Fever Update Patch Notes April 2026

If you have been competing online in Mario Tennis Fever on Nintendo Switch 2, the latest update should improve your experience. Nintendo recently rolled out a new patch aimed at smoothing out issues affecting the game’s online modes, offering relief for players who rely on ranked matches.

Since its February launch, the newest entry in Nintendo and Camelot’s long-running sports series has expanded the Mario franchise’s competitive lineup with 38 playable characters. You can choose from familiar heroes and villains, each built with distinct strengths that shape how you approach matches and refine your play style.

Mario Tennis Fever's New Update

Nintendo has rolled out version 1.0.3 for Mario Tennis Fever on Nintendo Switch 2. This patch focuses on a specific issue affecting Ranked Match progression.

Players reported that rankings did not update at the scheduled monthly reset time. The new update corrects that timing error so competitive standings now refresh as intended.

You should notice that rank adjustments now occur at the proper reset window for Ranked Match. This change restores consistency to competitive play and ensures leaderboard movement reflects match results on schedule.

Below is a quick breakdown of what version 1.0.3 addresses:

Unlike the March update, which introduced broader character and gameplay tuning, this release concentrates on system reliability. It does not introduce new modes or visible feature changes. Instead, it reinforces the competitive structure that active players rely on.

Nintendo has indicated that additional balance refinements are in development. You can expect further tweaks aimed at improving character performance and match flow in future updates.

Since launch, Mario Tennis Fever has received solid critical reception. Some reviewers consider it one of the strongest entries in the Mario Tennis series, though comparisons continue as more players spend time with it.

The title debuted earlier this year as one of the first major Nintendo Switch 2 exclusives of 2026. It joined a growing lineup that includes upcoming releases such as Yoshi and the Mysterious Book, Fire Emblem: Fortune’s Weave, and Splatoon Raiders, which arrives in July.

At the same time, Nintendo continues to support the original Switch platform. Recent and upcoming releases on that system include Tomodachi Life: Living the Dream and Rhythm Heaven Groove. New amiibo figures tied to properties like Resident Evil Requiem and Kirby Air Riders are also on the way.

You can expect more details about Nintendo’s broader 2026 plans in the coming months. Industry observers often look to early summer presentations for updates on major projects and possible downloadable content announcements. If competitive refinements continue, future patches may further shape how you experience Ranked Match play in Mario Tennis Fever.

Mario Tennis Fever Ver. 1.0.3 Patch Notes

Version 1.0.3 focuses on correcting an issue affecting Ranked Match standings on Nintendo Switch 2.

You will now see rankings update at the proper monthly reset time. The previous bug prevented standings from adjusting on the first day of each month at 5:00 p.m. PT, which caused inconsistencies in competitive play.

Update Details:

• Improved safeguards within the ranking system
• Corrected timing for monthly Ranked Match adjustments
• Ensured standings refresh as scheduled

These changes strengthen how the system processes leaderboard data and prevent missed resets.

Nintendo also confirmed that additional balance changes are in development. You can expect gameplay tuning in a future patch, though this update does not include character or mechanic adjustments.
