World 1-4 is the fourth and final level of World 1 in Super Mario Bros. and its remakes Super Mario All-Stars and Super Mario Bros. Deluxe. It is the first castle level in the game and the entire series.


The player starts in an elevated area with stairs that lead downwards, eventually ending at a lava pit. Following this is a platform surrounded by lava. It features a Fire-Bar, along with a ? Block above it, which contains a power-up. Up ahead is a corridor of Fire-Bars attached to the ceiling. After this is another room with Fire Bars attached to both the ceiling and the floor. Next up is a room where the player will find several Hidden Blocks before the bridge where the fake Bowser is found. Above the bridge is a horizontally moving platform.
