Page 6.</ref> and misspelled as '''Sup-Space''' on one occasion,<ref>M. Arakawa. ''NES Game Atlas''. Page 18.</ref> is an alternate dimension to [[Subcon]] in ''[[Super Mario Bros. 2]]''. In Subspace, the terrain is dark and mirrored on a single screen, which the player cannot travel beyond. Subspace can only be accessed by use of the [[Magical Potion]]s (which create doors leading to the land) in ''[[Super Mario Bros. 2]]''.

When [[Mario]] or his friends enter Subspace, they only have a few seconds to get the [[Mushroom]] that may or may not appear; it depends on where in Subspace the hero has entered. In Subspace, all items found in any available red [[grass]] are transformed into [[coin]]s when the player plucks them, giving the heroes a chance of earning extra lives in the slot machine [[Bonus Chance]] at the level's end, though they can only do this for the first two visits (any still-standing grass tufts give unripe [[vegetable]]s afterwards). Depending on the area, players can also collect [[Cherry|cherries]], [[Super Star|Starmen]], and [[POW Block|POW]]s. Cherries and POWs do not vanish upon returning to the main level, allowing one to effectively collect/use them twice.

Within this zone, a few [[jar]]s contain a '''Subspace Warp'''<ref>Farkas, Bart G. ''Super Mario Advance'' Official Pocket Guide. Page 105.</ref> that immediately allows the player to skip to another world, like a [[Warp Zone]]. In ''[[BS Super Mario USA]]'', entering any jar in Subspace sends the player directly to [[Wart]]'s chamber.

There are no enemies, but [[Phanto]] can follow the player into Subspace if they were holding the [[key]]. The player can still die by falling into a [[pit]] or drowning in [[quicksand]]. However, doing so will allow another chance to gain coins.

In the game's [[Super Mario All-Stars|two]] [[Super Mario Advance|remakes]], the background is the same, but the level terrain is colored-in, rather than black. Additionally, in ''Super Mario Advance'', [[Yoshi's Egg|Yoshi Egg]]s are hidden here after [[Wart]] is defeated.
