Super Mario Bros. codes: continue, world select and infinite lives
Every useful code and trick in the original NES Super Mario Bros., including the continue code and the 3-1 extra-life trick.
Original 1985 NES/Famicom game. Luigi shares Mario's movement in alternating two-player play. Super Mario All-Stars, Super Mario Bros. Deluxe and The Lost Levels change features or courses and are outside these guides.
Continue after a Game Over
On the title screen after a Game Over, hold A and press Start. You restart at the first level of the world where you lost your last life, instead of World 1-1.
World select in hard mode
After beating the game, the title screen offers the harder quest. Press B to change the world number before pressing Start.
Infinite lives in World 3-1
At the staircase before the flagpole, wait for a Koopa Troopa to walk down. Stomp it on the step so its shell sits against the stair, then jump on the shell repeatedly. The points climb until each bounce awards a 1-Up.
Warp Zones
There are no level-select codes, but the Warp Zones in World 1-2 and World 4-2 skip whole worlds. See the Where to find page for their locations.
