Secret Worlds in Super Mario Bros?!

You may have heard of the Minus World, but did you know there are 200+ more glitched worlds in Super Mario Bros.? This will be the first of many videos where I explore each and every one of them! There are still a ton left to explore, and even when we get through them all there will be even more to explore in different versions of the game!

i actually remember trying these worlds out when i was younger because some shitty plug and play 7million in 1 games had a version of super mario bros with the level select built in. and i remember thinking it was funny levels that were too big where just textures. glad to see a pro explore some of these weird levels. good stuff

@BronzeKaiser Kos regularly puts out good content and has zero bullshit on his channel. Saying something like what you said makes it sound like you haven't been around here long enough to know how he runs his channel. I don't say that to try to demean you either. I'm just saying it because I'd imagine that anyone who's followed his channel for any significant length of time would know that his focus is on legit content and not on antics or pandering.

I like to imagine the underwater castle levels are the same places as the real ones, but it's far in the future and they're abandoned and completely flooded. Also, the bridge destruction animation plays only when Bowser is there. In the normal game if you defeat him with fireballs (in addition to showing it wasn't really him) touching the axe also does not destroy the bridge.

Here's a fun little fact for you guys. Versions of SMB included in most unlicensed Famiclones (including, most notably, Power Player Super Joy III) allow you to cycle through worlds like this without use of a Game Genie. The B-button world selection method is not capped at 8 like in the retail game. I used to make a game of seeing where each wacky sprite character in the world counter took me. Of course, without anti-crash cheats many of the worlds were extremely unstable 🙄
