Diam is played on an octogonal board of 8 pawns. Each player has 8 pawns of 2 colors. At his turn, a player puts a pawn on the gameboard or moves a pawn. The pawns can be stacked on the same space until height of 4 pawns. A pawn can be moved from one space, all the pawns above are then moved at the same time. The winner is the first player who creates a Diam with one of his colors. A Diam is created when 2 pawns of identical color are at the same stack level face to face (on 2 diametrically opposed spaces). The lowest level is not taken into account. If 2 Diam are created at the same time, the higher Diam wins. You control the red and yellow pawns. To move a pawn, click on it, release the mouse, and click on the place where you want to put the pawn.
