Super Mario Bros.: The Lost Levels worlds

World A is the second secret world and the tenth world that was first featured in the game Super Mario Bros.: The Lost Levels, coming after World 9. World A can be accessed by beating the game eight times and then pressing the Start button while holding down the A button on the title screen (B Button in the Famicom Mini release) in order to access World A, and in turn the other later worlds. However, in the Super Mario All-Stars version of the game, the player proceeds to the later worlds directly after completing World 8 (or World 9 if the player accesses it by beating Worlds 1 to 8 without using warp pipes). World A and later worlds were left unused in the Super Mario Bros. Deluxe version of the game.
