This classic strategy board game involves two players attempting to capture squares on a chess-style board by the placement of counters coloured black on one side and white on the other.
A player places each counter so that it forms a horizontal, vertical or diagonal line, having one of his counters at the other end and at least one opposing counter between them. The outflanked counters are then turned over to form a continuous line of colour, and play continues. The winner is the player with the higher number of captured squares when all the counters are used.
