The battle-royale twist on the classic Tetris formula was developed by Arika and published by Nintendo as a Nintendo Switch exclusive in February 2019, and it has continued to run special limited-time events that offer cosmetic themes and music to players with an active Nintendo Switch Online subscription.
Nintendo of America announced on its official X account on June 25, 2026, that the 55th Maximus Cup will begin on Friday, July 10 at 12:00 a.m.
PT and conclude on Monday, July 13, 2026.
The post highlighted that the event will feature Tetriminos, music, art, and a new theme tied to the Star Fox franchise.
Rewriting that announcement in clear, journalistic language: Nintendo of America said on June 25 that Maximus Cup 55 will run from July 10 at midnight Pacific through July 13 and will spotlight new Tetrimino visuals, accompanying music and artwork, plus a Star Fox-themed customization option for Tetris 99 players.
How the Maximus Cup reward works
- Players can earn event points during Maximus Cup windows, accumulating up to 100 points to permanently unlock the event theme for use in Tetris 99 after the competition ends.
- Participation requires a Nintendo Switch console with Tetris 99 installed and an active Nintendo Switch Online subscription for access to the online-only game modes.
Star Fox context
Star Fox is a long-running Nintendo franchise that originally debuted on the Super Nintendo Entertainment System in 1993.
The series has been periodically referenced and celebrated across Nintendo platforms, and this Maximus Cup marks another collaboration between Tetris 99’s rotating event roster and Nintendo’s first-party IPs.
Tetris 99 continues to serve as a showcase for Nintendo’s event-based content model on the Nintendo Switch.
The game launched on February 13, 2019 and remains available to Nintendo Switch Online members.
Nintendo has not yet published screenshots or a full reveal of the Star Fox theme; when artwork and music are released, Nintendo and community outlets typically share the assets through official channels and the Nintendo eShop news feed.
