The goal is to capture 3 (or more) opponent stones. Game ends when a first player has captured 3 or more stones. A repetition of an exact previous position is forbidden. Other rules are similar to Capture Go.
An example game continuation is shown. White 1 cannot capture the black stone. Black 2 could connect black stone, but here it does not do it. White 3 may capture black stone, as stones 1 and 2 changed the whole-board position.
White may not capture black immediately after black capture, as this would produce the same whole board position as before black move. So white must play somewhere else. After this white may capture from A.
Capture 3 stones has an additional rule: A player may not play a stone so that it creates a past board position. So repetition of full-board position is not allowed.
