In World D-2, sometimes the springboard at the very end of the level will not appear.

To work around this glitch, Lakitu must be defeated before reaching this spot. 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. This appears in a few notable locations, including World C-3 and World D-2: In some levels, sprite overload can cause springboards that are necessary to pass a level to not appear. However, if the player does not collect the coin above the block first, then the power-up will not appear and the Brick Block will simply turn into an unbreakable block.

Normally, the right Brick Block contains a Power-Up. In the middle of World B-3, there are two adjacent Brick Blocks, each with a coin above it. For example too many sprites on screen can cause graphical errors to the character or environment, but does not massively affect gameplay. It is unknown how this is caused most likely due to programming errors or sprite limitation. However in the non-castle levels, if a flagpole is touched while the timer is at 0, no points are awarded at all. 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. This works in all versions, as well as the SNES and arcade version of Super Mario Bros.
