MAR10 Day 2025: Mario Kart Lego Set, Nintendo Music Additions, and Everything Announced

It’s March 10, 2025, so that means Nintendo is back with a slew of Mario Day reveals revolving around everyone’s favorite Mushroom Kingdom mascot.

As highlighted by the MAR10 hashtag floating around social media today, March 10 has served as Nintendo’s official (and clever) Mario holiday for the last few years. The appropriately named celebration always features announcements and treats for fans of the iconic plumber, and this year is no different. Although we’ve not yet seen anything quite on the level of 2024’s reveals, which included the promise that The Super Mario Bros. Movie 2 will arrive next year, 2025 has already delivered some exciting Mario news.

More Mario Offerings for Nintendo Switch Online Subscribers

Just hours before MAR10 Day officially kicked off, Nintendo announced that the Super Mario Bros. 3 original soundtrack had been added to its Nintendo Music application for Nintendo Switch Online subscribers. That means earworms like the World 1 Map tune Ground BGM are only a tap away, but there are even more deal sweeteners now available for Mario fans. Last Thursday, as an early surprise, Nintendo added the Game Boy releases of Mario’s Picross and Donkey to its library of Switch Online titles. It’s all available to help make MAR10 Day feel a bit more special right now.
