The first game of a match in each round is played on a fixed map. The maps for each round are written in the brackets page.
The losing player picks the map in following games from the map pool. The map pool is found in the General Rules thread, however it has since been updated to include more recent Elite mod maps such as Imperial Plaza and Lugganath Glacier.
Each player can veto a single map during a round, but not the fixed map of the round. Maps not in the map pool are automatically vetoed.
No map can be played more than once within a single round. This includes different "variations" of a single map, such as Pale Tooth Gorge and Green Tooth Gorge.
Players can select either random or 3 heroes prior to the tournament, seen on the participants page.
