Tetris 99 Maximus Cup Adds Super Mario Galaxy Theme for MAR10 Day on Nintendo Switch

Nintendo is celebrating Mario’s 40th anniversary in grand fashion this year with a series of high-profile events and releases across its key gaming platforms.

One of the major highlights for fans is the upcoming Tetris 99 Maximus Cup and Grand Prix, announced as part of the annual MAR10 Day festivities.

This special event intertwines two iconic franchises—Tetris and Super Mario Galaxy—right as Mario heads to the big screen with a new feature film. According to information provided on Nintendo UK's official website, the latest Tetris 99 Maximus Cup will be held from April 3 to April 7, 2026.

During this event, Nintendo Switch owners with an active Switch Online subscription can compete to unlock an exclusive in-game theme inspired by Super Mario Galaxy and Super Mario Galaxy 2.

To obtain the special Galaxy-themed visuals and music, players must accumulate more than 100 event points through online play. The introduction of this unique theme comes closely after the release of Super Mario Galaxy 1 and 2 on the Nintendo Switch in October of the previous year.

As part of their return to modern hardware, both games have received significant enhancements on the Nintendo Switch and are expected to feature additional improvements for the next-generation Switch 2.

The timing dovetails with growing excitement over the upcoming Super Mario Galaxy Movie, which is set to premiere in April, further cementing the legacy of this beloved series. In a statement echoing the event’s excitement, Nintendo representatives highlighted that the Maximus Cup offers players not only nostalgia but also a competitive way to celebrate Mario’s rich history on MAR10 Day.

The company emphasized that this event and others planned throughout the year reflect Nintendo’s commitment to honoring Super Mario’s enduring legacy in both gaming and popular culture. Earlier in the week, Nintendo hosted a dedicated Nintendo Direct presentation focused on the Super Mario Galaxy Movie.

The showcase included a brand-new trailer and a series of exclusive announcements, including Galaxy-themed items arriving on the My Nintendo Store in North America.

These moves are part of a broader celebration that positions Mario at the heart of Nintendo’s strategy for engaging fans across games, movies, and merchandise alike. Fans interested in the Tetris 99 Maximus Cup should ensure their Nintendo Switch Online membership is active ahead of the April 3 kickoff.

Stay tuned to official Nintendo news channels for updates, including potential video previews of the new Galaxy theme as MAR10 Day approaches.
