Mario Tennis Fever Serves Up Another Small Switch 2 Update, Here Are The Patch Notes
Nintendo has released version 1.0.3 of Mario Tennis Fever for Switch 2, continuing its post-launch support for the game. The update, which launched on April 22, 2026, remains modest in scope, focusing on bug fixes rather than introducing major new features or changes.
The primary change in this patch addresses an issue with the Ranked Match ranking system. The update includes adjustments to how and when rankings are recalculated, serving as a countermeasure to a previously identified bug that affected competitive play. Beyond this fix, the patch notes appear minimal, with no mention of additional balance changes or feature additions in the current update.
Nintendo has indicated that further balance adjustments are planned for future updates, suggesting the development team is monitoring gameplay and may introduce more substantial changes down the line. This approach is typical for live-service games, where incremental updates are staggered to test changes and gather player feedback before rolling out larger adjustments.
