1.The stones and the board work with the concept of mortise and tenon. The stone has a cone on one side, which functions as a peg to match holes on the board. With the cone-shaped peg, the stones sit firm on the indented intersections. The peg helps the stone remain steady at a touch.
2.The pegged stones sit neat on the board. Any straight, horizontal or diagonal row of stones is easily spotted, which saves ambiguity and also the ensuing dispute.
3.The white stones can easily be collected with a magnet. The metal peg on the stone helps save time when the white stones are separated from the black ones
