Map Set
The Map Set is the pool of Maps players can select from in Custom Online and Couch Party lobbies. This can be configured in the settings menu in the lobby of these gamemodes.
By default, the map set is configured to "Auto", which will automatically select a map set based on how many players are in the lobby. If you do not want to play by a specific map set, the "All" map set will simply allow any map from the gamemode to be selected.

Dice & Destruction
Dice & Destruction features 5 unique map sets, alongside using the standard Tournament 1v1 and Tournament 2v2 sets. These map sets are similar to their standard counterparts, typically only removing maps with ceilings or high item spawns from the pool.
