World 1-4 is the final course of World 1 in Super Mario Bros. It is a castle course and the Bowser Impostor found in the level is actually a Goomba.



The player starts the level on an elevated area with stairs heading downwards, ending at a pit of lava. Afterward is a platform with a Fire Bar and surrounded by lava, with a ? Block containing a power-up above it. After a corridor of Fire Bars on the ceiling, there is a room with more Fire Bars placed on both the ceiling and the floor. Next is a room containing several Hidden Blocks before the bridge with the Fake Bowser, which has a horizontally moving lift above.
