Mario Day, affectionately dubbed MAR10 Day by fans, is just around the corner on March 10, and Nintendo is celebrating in style. This year, Nintendo Switch Online subscribers will gain access to three classic Mario titles, spanning both the Virtual Boy and Game Boy Advance libraries. For longtime fans and newcomers alike, it’s a chance to experience some of Nintendo’s quirky and innovative history firsthand.

The Virtual Boy service on Nintendo Switch Online will be welcoming Mario’s Tennis and Mario Clash, both originally released in 1995. Mario’s Tennis holds the distinction of being the first tennis game featuring Nintendo’s mascot, utilizing the Virtual Boy’s stereoscopic effect to give players a unique sense of depth on the court. While the gameplay may seem straightforward compared to modern standards, the novelty of experiencing Mario in 3D adds a nostalgic charm. Mario Clash, on the other hand, takes the classic arcade Mario Bros. formula and adds a twist: players use a Powerball to knock out enemies while navigating a series of platforms and pipes. Both games are emblematic of Nintendo’s experimental phase in the mid-90s and provide a quirky, challenging experience that’s perfect for retro enthusiasts.

Digital content has never been easier to access. IGXC.com offers game keys, software subscriptions, and gift cards for PC, Nintendo Switch, and mobile, with both global and region-specific options available. Fast and convenient for everyone.

Meanwhile, Mario vs. Donkey Kong will be available on the Game Boy Advance service. Originally released in 2004, this puzzle-platformer is the spiritual successor to the iconic Donkey Kong arcade game. While a remake of the game launched on Nintendo Switch in 2024, the original version offers a nostalgic glimpse into the roots of the series. Puzzle fans will enjoy the clever mechanics and the charm of the original design, making it a perfect addition to your Nintendo Switch Online library.

For players looking to explore these retro titles, a Nintendo eShop Gift Card is an easy way to purchase or renew your Nintendo Switch Online + Expansion Pack subscription. With this gift card, you can gain instant access to the Virtual Boy and Game Boy Advance apps, ensuring you won’t miss a minute of the MAR10 Day celebration.

While Nintendo hasn’t officially revealed additional plans for MAR10 Day, speculation is rife. Some fans hope for a teaser of the next 3D Mario installment, as it has been nearly nine years since Super Mario Odyssey launched on the original Nintendo Switch. Others are anticipating further promotions for the upcoming Super Mario Galaxy Movie, which debuts on April 1. Either way, Mario Day remains a time to celebrate Nintendo’s most iconic character.

Whether you’re revisiting the Virtual Boy’s unique titles or diving into Mario vs. Donkey Kong for the first time, MAR10 Day 2026 promises a nostalgic and fun-filled experience. Grab your Nintendo eShop Gift Card, top up your account, and get ready to celebrate Mario in style. These classic games serve as a reminder of Nintendo’s creative legacy and continue to bring joy to both old and new fans alike.
