Like Hex, Twixt , Connections , and similar games, the object of Antipalos is to connect opposite sides of the board. Antipalos is played on a 16X16 square grid. Pieces are played diagonally across the squares. It is possible (unlike Hex and Twixt ) for opposing lines to cross each other. Players are limited in the number of pieces that may be played. When the limit is reached, players must remove pieces and reposition them. - BoardGameGeek
