Abstract: A game may be executed that may provide game objects to a plurality of players such that a characteristic of the game objects for each of the plurality of players may be visible to other players. The game may also receive an arrangement for the game objects from each of the plurality of players. To begin play, the game may select a first player from the plurality of players. The game may then determine whether a first game object of the arrangement for the game objects of the selected first player may be playable. The first game object may then be removed from the game objects of the selected first player if the first game object may be playable.
