Warp Zone

The Warp Zone is a hidden area that acts as a kind of teleportation system, connecting many worlds to one place. For the most part, they are sectioned-off areas containing Warp Pipes, although Super Mario Bros. 3 featured an entire island as its Warp Zone. Instead of Warp Zones, New Super Mario Bros. and two of its sequels feature Warp Cannons accessed from secret exits in certain levels, each of which would launch Mario or Luigi to a later world.

Certain jars within Subspace in Super Mario Bros. 2 contain Subspace Warps which automatically warps players to later worlds, without the use of an intermediary Warp Zone. In some episodes of The Super Mario Bros. Super Show!, King Koopa would similarly use potions to create portals or doors to make his escape.

In Super Mario World, players can skip directly to the Front Door of Bowser's Castle by accessing the Star World via Star Roads connected to Donut Secret House, Vanilla Secret 1, Soda Lake or Forest Fortress, and then clearing the paths to the final warp (itself directly accessed from Valley of Bowser 4).

Similarly, New Super Mario Bros. U and New Super Luigi U have secret exits in some levels that allow users to skip to later worlds, as do New Super Mario Bros. and New Super Mario Bros. Wii. These special levels are the following (the first link of a pair indicates New Super Mario Bros. U level, the second link the New Super Luigi U level): Blooper's Secret Lair/Cheep Chomp Chase (in Acorn Plains) and Piranha Plants on Ice/Slippery Rope Ladders (in Layer-Cake Desert) leads to Soda Jungle, Skyward Stalk/Beanstalk Jungle (in Sparkling Waters) and Fliprus Lake/Fliprus Floes (in Frosted Glacier) leads to Rock-Candy Mines, Flight of the Para-Beetles/Para-Beetle Parade (in Soda Jungle) leads to Meringue Clouds.

Super Mario Bros.
In Super Mario Bros., the zone is a sectioned-off area containing pipes to different levels. There are three of them; one located in World 1-2 and two in World 4-2. The first gives the choice to warp to World 2, World 3, or World 4, and is located behind the pipe that leads to the Flagpole. In World 4-2, the zone behind the final pipe leads to World 5 only. Instead, the player must find a secret Beanstalk in order to warp to World 6, World 7, or World 8. The first Warp Zone also lets players perform the famous Minus World glitch.

In Super Mario Bros. Deluxe, the Warp Zones are replaced by additional level design in the game's Challenge Mode.

Super Mario Bros. The Lost Levels
In Super Mario Bros.: The Lost Levels, Warp Zones function identically to those in Super Mario Bros. They no longer, however, give the player a choice of destination, as every zone contains only one pipe. Two Warp Zones send the player to an earlier World; for instance, the Warp Zone in World 3-1 leads to World 1-1, and the Warp Zone in World 8-1 leads to World 5-1. However, the backwards Warp Zone in World 3-1 has a gap that Mario can chose to jump into and lose a life to avoid the pipe. This time, to prevent glitching by jumping over the flagpole, some Warp Zones are located behind it.

Using Warp Zones voids access to World 9; this condition does not apply if the player uses a backwards Warp Zone. In Super Mario All-Stars, saving after doing this removes access to World 9 permanently for that save file. Due to World 9 (as well as Worlds A through D) being absent in the Super Mario Bros. Deluxe port, this condition does not apply in that version.

The Warp Zone locations in this game are, in order of appearance:

Super Mario Bros. 3
In Super Mario Bros. 3, the Warp Zone is an island (treated as the game's World 9) that can only be accessed via Whistle. Like other games' Warp Zones, it connects to the other kingdoms of the Mushroom World, although the zone itself is not completely interconnected; to access the top row, one must warp from World 1; to access the middle row, one must warp from Worlds 2-6; and to access the last row, one must warp from Worlds 7-9. Alternatively, one can collect two Whistles using the first to access the Warp Zone and the second while within the Warp Zone to access the last row to enter World 8.

Super Mario Advance 4: Super Mario Bros. 3 shortened the text at the top of the Warp Zone from "Welcome to Warp Zone" to "World 9 Warp Zone!". Although the world cannot be selected from the World Select screen (due to it requiring special circumstances to access), it is most likely the small island near Desert Land, Water Land, and Giant Land, due to it being a small island with the same coloration as Warp Zone.

Additionally, the original Super Mario Bros. Warp Zone is replicated in Classic World 1-2, though all three pipes only send the player to one room with a Fire Flower in a chest.

Super Mario 3D Land / Super Mario 3D World
Warp Zones also appear in Super Mario 3D Land and Super Mario 3D World. They are in the same levels as they were in the original Super Mario Bros.: in World 1-2 and World 4-2. However, there is only one orange pipe, and they only warp the player to the next world.

Super Mario Bros. 35
In Super Mario Bros. 35, instead of sending the player to the beginning of a world, the pipes in the Warp Zone, from right to left, skip 1, 2 or 3 levels respectively in the randomized level order ; this means they may also warp to an earlier level, or loop through the current level, similarly to backward Warp Zones in Super Mario Bros.: The Lost Levels.

Captain N: The Game Master
Characters in Captain N: The Game Master frequently used Warp Zones for means of rapid transit, with the Warp Zones of Super Mario Bros. even being referenced to in the show's first episode.

Super Paper Mario
A model of a Super Mario Bros.-style Warp Zone can be found in the underground section of Chapter 3-1 (itself a recreation of Super Mario Bros. 's World 1-2) in Super Paper Mario, though this Warp Zone takes the player to other parts of the current level rather than different worlds. It does not serve any real function other than to take the player back to the overworld. The Warp Zone is also mentioned by the defeated Warping Pipe Sammer Guy in Super Paper Mario, who believes it to be a fabled place where great warriors (apparently people with incredible skill over Warp Pipes) tread.
