List of Super Mario Bros.: The Lost Levels glitches
This is the glitches found in the game, Super Mario Bros.: The Lost Levels.
Note that most glitches that work in Super Mario Bros. will also work in this game, with a few exceptions like the Minus World.
Fireball Through Compact Space
This only works in the classic version. In World 4-2 near the second Hammer Bro., there is a corner. The player should shoot a fire ball there and it will, with a one in ten chance, go through the corner.
Hammer Immunity
This glitch works in all versions. When encountering aggressive Hammer Bros. (i.e. the ones that run left towards Mario/Luigi), it is possible to be immune to their hammers. All the player has to do is stand on the left edge of the screen, and the hammers will not hurt Mario or Luigi. This greatly facilitates defeating them.
Disappearing Springboards
These glitches only work in 8-bit versions. In some levels, sprite overload can cause springboards that are necessary to pass a level to not appear. This appears in a few notable locations:
World C-3
There is one springboard in the middle of the level (which is necessary to beat the level) which will not appear if Lakitu is on the screen. To work around this glitch, Lakitu must be defeated before reaching this spot.
World D-2
Sometimes the springboard at the very end of the level will not appear. This typically happens if the last red Paratroopa (to the right of the high row of brick blocks) is jumped on (which causes it to move to the right, towards the springboard).
999 Timer
This works in all versions, as well as the SNES version of SMB. In any castle level, if an axe is touched while the timer is at 000, it will loop to 999 and award the player plenty of points.
Walk through walls in wind
This glitch works in all versions. In levels where wind is blowing to the right, it is possible to walk through walls. One must touch the left side of any wall and repeatedly tap Left. Eventually Mario/Luigi will get sucked into the wall and slide to the right. Doing this on a pipe with a red Piranha Plant will sometimes kill Mario though, if the Piranha Plant is inside its pipe, which can be observed in World D-4.
