'''World 7-1''' is the first level of [[Pipe Land]] in ''[[Super Mario Bros. 3]]''. It is immediately accessible after the player has cleared [[Ice Land]] and its own completion unlocks [[World 7-2 (Super Mario Bros. 3)|World 7-2]].

==Layout==
Unlike most other levels, this level has the player climb up vertical platforms and the player can "wrap" around the stage, meaning if they move of the left side, they will appear on the right and vice versa. The player starts in an outside area, with the door to the right leading into the actual level. The player will appear at the bottom of the level and has to [[jump]] up some narrow platforms to reach one of two hanging [[Warp Pipe]]s leading upward. The player then has to avoid [[Piranha Plant]]s as they try to enter the next hanging pipe, which will take the player upward and to the right. Here, if the player manages to jump around the [[? Block]]s or fly up using a [[Super Leaf]] or similar power-up, they can find a [[1-Up Mushroom]] in a [[Hidden Block]]. Continuing upward requires taking the Warp Pipe on the left, because the one on the right leads back down.

On top of the curved pipe is a [[Koopa Troopa]] that can be used to hit the grounded ? Blocks and cause a power-up to appear out of the block to the left, and by using a [[Note Block|Jump Block]] to jump onto a floating pipe above, the player can continue upward. The player will then jump through a pipe that wraps around the stage, which the player can use to build their [[P-Meter|Power Meter]] and fly up to the left to reach a pipe leading to a room full of [[coin]]s. If the player does not have a flight power-up, they will have to jump up pipes to the right, avoiding Piranha Plants and using Jump Blocks to gain additional height. After either path, the player will have to go through a hanging pipe to a small room with Koopa Troopas and a [[Koopa Paratroopa]], the later of which can be used to reach an invisible block near the Warp Pipe containing a 1-Up Mushroom. Through the Warp Pipe is the [[Goal (Super Mario Bros. 3)|goal]].

===Glitch===
The [[Family Computer]] (and [[Nintendo Entertainment System]]) iteration of this level has a "wrong warp" glitch that can allow for arbitrary code execution, typically used by speedrunners to take Mario straight to the scene where [[Princess Peach]] is saved at the end of [[World 8-Bowser's Castle (Super Mario Bros. 3)|the final castle]]. With precise timing, Mario can enter from the wrong side of the rightmost Pipe of the bottom two in the main area, causing him to warp downward into glitchy garbage tiles resembling the top of the level. Precise manipulation of various Koopas is used to control what code is executed.<ref>{{cite|url=https://www.youtube.com/watch?v=fxZuzos7Auk|author=Retro Game Mechanics Explained|title=Super Mario Bros. 3 - Wrong Warp|date=November 25, 2016|publisher=YouTube|accessdate=May 19, 2024}}</ref> This glitch can be done in the ''Super Mario All-Stars'' version, though it will "properly" wrap Mario around to the top of the level, while the glitch has been entirely fixed for the Game Boy Advance version. A similar glitch exists on [[Yoshi's Island 2]] in ''[[Super Mario World]]''.
