Mario Day, or MAR10 Day, lit up gaming screens worldwide on March 10, 2026, celebrating Nintendo’s iconic plumber who’s been jumping levels since 1981. Fans went wild with nostalgia, smashing buttons on classics while hunting epic deals—because who doesn’t love a mustache-fueled excuse to game all day?
The date’s genius? Write “March 10” as MAR10, and bam—it spells Mario! Fans started this unofficial holiday over a decade ago, but Nintendo jumped in officially around 2016 with sales, events, and freebies. In 2026, it hit different amid new Switch 2 buzz and Super Mario Bros. Wonder DLC drops.
From Tokyo arcades to U.S. living rooms, millions marked the day—over 260 million Mario games sold lifetime prove why this red-hatted hero rules pop culture.
Origin of the Mustache Magic

Mario debuted as “Jumpman,” a carpenter battling Donkey Kong in 1981. By 1983’s Super Mario Bros., he was the Italian plumber saving Princess Peach (or Toadstool, depending on the era) from Bowser’s clutches.
Nintendo credits fan cleverness for MAR10—early Reddit posts from 2009 spotted milk cartons expiring “MAR10.” By 2015, Nintendo tweeted holiday wishes, and now it’s annual madness with quizzes, polls, and Mario-Kart takeovers.
Fun fact: Mario’s full name? Mario Mario. Brother Luigi makes ’em the Mario Bros. He’s popped up in 200+ titles, outselling Pokémon as gaming’s top franchise.
