Diam is an arcade game on www.flash-game.net which is played on an octagonal board of 8 pawns. Each player has 8 pawns of 2 colors. At his turn, the player puts a pawn on the gameboard or moves a pawn. The pawns can be stacked on the same space until the height of 4 pawns. A pawn can be moved from a 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 time stack level face to face. The lowest level is not taken into account. If two Diam are created at the same time, the higher Diam wins. Good luck!
