In a sense, passcode levels may be the pinnacle of what's possible in Super Mario Maker 2. Practically speaking, these passcodes are unbreakable. This means if you don't know a level's passcode, it's almost impossible to arrive at it through brute force. In Super Mario Maker 2, Nintendo also removed the ability to open up other players' levels in the editor to discover how they're made.

These levels are ultimately cryptographic exercises: the creators make sure there's no way to deduce the passcode from any cues or hints in the level.

Instead, they're more of a way for their creator to demonstrate what's possible with Mario Maker's level creation tools. Passcode levels are counter-intuitive in that they aren't intended to finished. "It's just about exploring what can be done and having fun with it along the way." So why do it? "For me it's not so much about winning," Veedrac tells me over Discord. Veedrac went to these great lengths even though three other levels with similar (albeit less secure) passcode systems already existed in Super Mario Maker 2. That's nearly 8 continuous minutes of precise block breaking, all to put up a level Veedrac describes in his wryly hilarious explainer video as "the utter pinnacle of poor life choices." With a 500 second timer and absolutely no room for error in entering the passcode, Veedrac completed his upload attempt with 21 seconds to spare. To beat the level, the player has to enter a 752-digit binary passcode by way of breaking certain brick blocks-that's the only way to get a key to the level's exit. Nobody has beaten Super Mario Maker 2's "Longest Passcode Level." save for its creator, Veedrac.
