In celebration of Mario's 40th anniversary and to build anticipation for the forthcoming Super Mario Galaxy film, Nintendo is launching a special collaborative event within its popular battle royale game, Tetris 99. Participants in this limited-time event, running from April 3rd to April 7th, 2026, have the opportunity to acquire a unique Super Mario Galaxy-themed interface. Achieving this requires players to earn more than 100 points through gameplay, integrating the beloved space-faring adventure into the fast-paced puzzle action. This initiative also introduces new Switch user icons inspired by the Mario Galaxy series, distributed in five distinct waves, enriching the customization options for fans.

Nintendo initially revealed this crossover during the annual Mario Day festivities in March. The announcement highlighted the integration of Super Mario Galaxy elements into Tetris 99, providing a fresh experience for players of the Nintendo Switch Online title. A visual preview of the new Galaxy theme was also shared, giving enthusiasts a glimpse into the cosmic aesthetics awaiting them.

The event is specifically tied to the release of Super Mario Galaxy and its sequel on the Nintendo Switch platform, which occurred in October of the previous year. These classic titles have also reportedly received graphical improvements tailored for the upcoming Switch 2 console, indicating a forward-looking strategy from Nintendo. The timing of this Tetris 99 event further aligns with the release of the Super Mario Galaxy movie, amplifying the excitement across various Nintendo franchises.

Adding to the fan engagement, Nintendo recently hosted a Direct presentation for the movie, showcasing a new trailer and other related announcements. Moreover, exclusive Galaxy-themed merchandise has been made available on the My Nintendo Store in North America, allowing fans to extend their celebration beyond the digital realm of gaming.

To participate in this stellar Tetris 99 event and unlock the special Super Mario Galaxy theme, players must have an active Nintendo Switch Online subscription. This initiative not only celebrates a significant milestone for the Mario franchise but also offers a nostalgic yet novel way for fans to engage with two distinct gaming universes, all while hinting at future enhancements and cinematic ventures for their beloved characters.
