One of the players takes black "stones" and the other player takes white "stones". The board is a grid of 9 by 9 lines. The game starts with 4 stones are on the board as shown in the diagram. Black player starts the game. Each player plays a single stone of their own color. A player can play to any empty intersection. A player may not pass. Once the stone is played it is never moved to another intersection.
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.
It is possible to search games for position or players. Search covers games from well-known public WEB archives, more that 90000 professional games are available. You can also include your games in the device to the search.
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.
