The Great Maze is the 31st and final level of the Subspace Emissary in Super Smash Bros. Brawl. After many sections of the World of Trophies are sent to Subspace, Tabuu creates a large maze comprised of sections from most of the previously visited levels in the game. To complete this, the player must win a number of battles, against Subspacial clones of all the characters in the game (excluding Sonic, Jigglypuff, Toon Link, and Wolf), and against all of the bosses (except for Master Hand and Crazy Hand).

There is no specific order in which the player must beat all the enemies, and it is possible to play as any character that has been rescued so far. Save Points and Warp points are dispersed throughout the maze. These two types of checkpoints are indicated by the Smash Bros. emblem mounted on a trophy stand and look like a forest clearing with a Subspace rip in the fabric of the sky. Save Points restore the player's stock to 4 (6 in later runs) and damage to 0%, as well as letting the player re-select characters or fiddle with stickers. Warp Points are identical but also allow teleportation between other visited Warp Points, as well as serving as both entry and exit points to and from the maze itself.
Pausing at any time displays a map of all visited rooms, as well as the player's current position inside a room and where doors and room-to-room links are. Once enough rooms have been visited to form a loop with the starting point, the map will also display all the locations of unbeaten characters and bosses with icons in the form of a monster head.
Once all battles are completed, a large purple door becomes accessible in the center of the maze, which leads to Tabuu's Residence. Upon winning this final battle, the Great Maze is spread apart and all the levels and locations of the World of Trophies are returned to their normal state. The Isle of the Ancients, however, is not restored: the great number of Subspace Bombs going off in one place has taken it beyond repair. Afterwards, the Great Maze remains on the world map so that the player can re-enter it for completion later, and the stages on the Isle of the Ancients are still playable.
If no trophies are rescued in Subspace, the player will still have six characters to choose from in The Great Maze: Ness, Luigi, and Kirby are revived by the Brooches; King Dedede is revived by Luigi and Ness; Bowser is revived by King Dedede; and Sonic appears at the very end of the Great Maze. All other characters with the exception of Toon Link, Jigglypuff, and Wolf must be revived as trophies in Subspace.
The fights against each subspacial clone each take place on a unique stage. A gallery of these stages can be found here.
Tabuu's Residence is the common fan name given to the stage on which the player fights Tabuu. It is very similar to Final Destination, consisting only of one similarly long and purple platform, though slightly longer and differently patterned (with a central design similar to that on Tabuu's wings); and with its own background visuals, somewhat reminiscent of the version of Final Destination in Super Smash Bros. Melee. Its music is titled Boss Battle Song 2. The stage can be accessed in other modes via hacking techniques.
The Great Maze has many different music tracks in it, some of which only appear during the fights with the dark clones or the bosses.

- Despite having only 4 stock at a time available for the initial playthrough, 6 are available on any successive playthroughs. This is likely due to two reasons; the possibility that the player did not retrieve any trophies in Subspace Part I and II (leaving them only five characters for use) and that subsequent playthroughs do not allow for a refreshed stock post-cutscene before Tabuu.
- Some parts of The Great Maze are combinations of older stages, such as The Forest with the day-changing doors from The Lake, and the three-switch doors from the Subspace Bomb Factory in the original recreation of The Research Facility.
- Also, there are a few new areas in some of the older stages that didn't exist before, such as the elevator rooms in both The Halberd and The Research Facility, the mountain entrance to The Battlefield Fortress, and the icy floors in The Ruined Zoo.
- Nevertheless, there are also some stages that aren't even a part of the Great Maze at all, such as The Plain and the Sea of Clouds.
- Some of the area recreations are laid out in such a way that the player will go through a level in the opposite direction from the first time, such as the Ruined Zoo, the Wilds and the Battlefield Fortress.
- Many of the stage remakes have different music than the original versions.
- There is not a single R.O.B. in the Great Maze (except the playable one). This suggests that they have all been destroyed in the Isle of Ancients.
- The Halberd was destroyed and never entered Subspace, yet all three of its playable sections still show up in The Great Maze.
- At the very least, 9 bosses/Subspacial clones must be defeated to form a loop back to Midair Stadium: Petey Piranha, Link, Diddy Kong, Samus, Ridley, Mario, Galleom, Lucas, and Lucario.
