Diam is played on an octogonal board of 8 pawns. Each player has 8 pawns of 2 colours. 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 a 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 colours. A Diam is created when 2 pawns of identical colour 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 have the red pawns and the yellow panws, the computer has the black pawns and the brown pawns. To move a pawn, click on it, release the mouse, and click on the place where you want to put the pawn.
