Super Mario Bros. (Nintendo Entertainment System, 1985)

More of a glitch than an Easter Egg , this one (there doesn’t seem to be many around in the NES era). By passing through a solid wall near the exit in world 1-2, it is possible to travel to “World -1, also known as the “Minus World” or “World Negative One” and considered by the game to be “World 36.” This stage is identical to Worlds 2-2 and 7-2, but upon entering the warp pipe at the end, the player is taken back to the start of the level.

We have actually done this one here at purenintendo. It was cool until get stuck int the minus world.
