Mario games and community-created challenge runs go back decades but most aren’t being run against a ticking clock. After multiple years of coordination, however, a group of Super Mario Maker players has completed the ultimate test—clearing every unbeaten level before the game’s servers shut down—with one hiccup.
Known as Team 0%, the group started in 2017 trying to clear the 13,000 uncleared levels that were uploaded within the first year of Super Mario Maker’s Wii U release in September 2015. That goal was accomplished in less than a year and the team had grown substantially over that period as they continued to truck along and clear as many levels as possible while players were still creating new ones.
