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.

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 0, it will loop to 999 and award the player 50,000 points. However, if a flagpole is touched while the timer is at 0, no points are awarded at all.

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, including World C-3 and World D-2:

In 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.

In 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).

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.

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.

Similar to the World 3-1 shell trick in Super Mario Bros., there's one you can pull off in the first level. The first Red Koopa Troopa the player will encounter is trapped in a box. Hit the second brick on the bottom to sprout a Super Mushroom, then bump it from below to pop it over the right wall and down to the ground. The player must run over and get it, making sure not to scroll the left side of the screen past the left wall of the box. Now that Mario is "super," the player must wait until the Red Koopa Troopa is next to the right wall, and break the third brick to trap him next to the wall. Then go back and break the first brick, then jump up to the block that gave Mario a Mushroom. Smash the brick above Mario, and then the one next to it on the right, hopping onto the Red Koopa Troopa in the process. Mario will keep bouncing on it's shell, racking up extra lives.

The game won't let the player have two power-ups on the screen at the same time. Thus, they can make a Poison Mushroom disappear by sprouting a Super Mushroom.

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. This glitch also works in the remake Super Mario All-Stars, and may also work in Super Mario Bros. Deluxe, but the player has to duck after being stuck and jump to get into the wall.
