'''World 9''', also presented in the in-game text as '''Fantasy World''' and “'''9 World'''”, is the first secret [[world]] and the ninth world in ''[[Super Mario Bros.: The Lost Levels]]'', unlocked when the player defeats [[Bowser]] while clearing all 32 of the game's standard levels in that playthrough. Usually, this entails using no [[Warp Zone]]s, though it is possible to use the backward Warp Zone in 3-1 to return to 1-1, then warp from 1-2 forward to 3-1 again, or use the backward Warp Zone in 8-1 to return to 5-1, then warp from 5-2 forward to 8-1 again and still unlock World 9. Unlike all other worlds in the game, this world has three [[level]]s that take place underwater, as well as a castle that is not the last level of the world. According to an interview given in Family Computer Magazine, [[Shigeru Miyamoto]] added World 9 to the game due to interest in a glitch exclusive to the Japanese version of the original ''[[Super Mario Bros.]]'', where using said glitch to access that game's nonexistent World 9 would load the overworld level [[World 6-2 (Super Mario Bros.)|6-2]] with the underwater palette and physics, creating a [[Minus World]]-esque effect.<ref>[http://legendsoflocalization.com/super-mario-bros/misc/ Legends of Localization Super Mario Bros.: Miscellaneous]</ref><ref>[https://archive.org/details/family-computer-magazine-issue-9-april-1986/Family%20Computer%20Magazine%20-%20Issue%209%20-%20April%201986%20%28Compressed%29/page/69/mode/2up Famimaga, April 1986. Pages 68-69.]</ref>

The mechanics of World 9 differ depending on the version of the game. In the original release, the player is given only one life to get through World 9 (though they keep their score, coins, and power-up status from World 8-4), though they can still gain more lives by gaining enough coins and from reaching the flagpole under certain conditions. The [[Game Over]] screen for this world, like the opening screen, features a unique message; as a result, the usual options are not displayed and the player effectively cannot choose to continue. If the player clears World 9-4, the game goes back to World 9-1 and the four levels of World 9 loop endlessly until the player receives a Game Over. In the ''[[Super Mario All-Stars]]'' remake, the player retains all the lives they had upon completing World 8-4, and clearing World 9 advances the player onward to [[World A]]. 

Aesthetically, Worlds 9-1 and 9-2 in the original FDS version appear as flooded overworld levels with some underwater tiles and underwater palettes, causing parts of the landscape to appear out of place and very discolored (intentionally matching the Minus World glitch effect mentioned above). In the SNES version, overworld tiles are still used, but with more accurate palettes.

In Volume 52 for ''[[Nintendo Power]]'', a contest was held where the player needed to get to World 9 in ''Super Mario Bros. The Lost Levels'', and supply photographic proof that they did so. Anyone who succeeded in doing so would be supplied with {{media link|World-9-patch.png|an iron-on patch}} commemorating the occasion.

All secret worlds are inaccessible in the ''[[Super Mario Bros. Deluxe]]'' port, World 9 included, although their data still remains in the game.

==Game Over==
As noted above, the Game Over for World 9 in the original Disk System version was unique compared to the other Worlds. Specifically, the world's game over lacks the options for continuing the current level or retrying the game, requiring the player to go back to [[World 1 (Super Mario Bros.: The Lost Levels) | World 1]]. Instead, in its place, there is a message attributed to Mario as well as the staff for the game telling the player that they are a "super player", and that they hope they'll see the player again

In the SNES version, it just uses the standard game over screen.

==Trivia==
*This is one of only two playable worlds in the ''Super Mario'' side-scrolling games to not include a true castle level, the other being [[World 9 (New Super Mario Bros. Wii)|World 9]] in ''[[New Super Mario Bros. Wii]]'', which is also a bonus world that unlocks after completing the game. However, World 9-3 does have a similar theme to the castle levels, though it takes place outside.
