Super Mario Bros has glitched worlds that go far beyond the normal game… but what happens when the levels start repeating forever? In this episode, we explore the endless looping worlds hidden deep inside the NES cartridge. In Glitched Worlds Part 13, Mario enters a series of broken levels where progression stops entirely. Worlds repeat, pipes lead back to the same place, and Coin Heaven transforms into a trap with no escape. These strange levels (Worlds 161–190) reveal what happens when the game’s memory begins to collapse. From repeating level chains to infinite coin loops and corrupted environments, this is one of the strangest discoveries yet in Super Mario Bros.
