Tohuwabohu consists of a board, bricks, tiles and pawns. Also, each player holds a number of task cards. A timer is started and makes sounds in 15-second intervals.
The active player now tries to fulfill the task on one of his cards within 15 seconds. Tasks can involve bricks, tiles or pawns. Existing structures can be expanded, modified or torn down. The first player to fulfill all of his task cards is the winner.
