Rush is a territory game played with a Go set. Players take turns adding their own stones. Players cannot add a stone which is horizontally adjacent to two or more stones, if all of the connecting stones are the same color as the added stone. If a player adds a stone which forms two or more connections, he must add another stone during his turn, and keep adding stones during his turn until his most recent stone connects to one or less stones, concluding his turn. The object is to have the majority of stones on the board when the board fills up.
