Originally this type of chess was played with Go pieces (white and black pieces) on a Go board (19x19). Black goes first and the players take turns placing one of their pieces on the empty intersection. The winner is the first person to get a continuous sequence of 4 horizontal, vertical, or diagonal pieces with no headshots. If one is blocked, the player needs to have a sequence of 5 consecutive cards to win. If the sequence of 5 consecutive pieces is blocked at both ends, the game continues. Once placed, the pieces cannot be moved or removed from the table, so this type of chess can be played with pen and paper. In Vietnam, this chess is often played on student paper (checkered boxes are available), using a circle marker (O) and the letter X to represent 2 pieces.



Among such additional rules, the renju rule (as the Japanese name it) is the most complex and strict, and also helps to balance the chances of white (behind) with black.
