This is a game for two players where the object is to be the first to make a line of five adjacent pieces either across the board or down or diagonally. The players take it in turns to place a piece in a square on the board and once placed the pieces cannot be moved. Go Moku is played on a 19 by 19 Go board, the players having 180 stones each.
You can make your own board for the game marking out a 10 by 10 square into 100 small squares, or a larger square up to 19 by 19. You will need a large supply of counters of two colours. Alternatively you can play the game on paper by printing off this grid, and in this case, instead of putting down counters, players make individual marks in their chosen squares.
In the traditional game the pieces are placed on the intersection points where the gridlines cross (as in Mulinello) but it is exactly equivalent, and easier to play, if you place the pieces inside the squares.
