Each player has a set of 20 tiles of different shapes and sizes: 12 x 5-size, 5 x 4-size, 2 x 3-size and 1 x 2-size (88 squares in total). The game is played on a 14x14 board, but five 2x2 spaces are forbidden areas - giving 176 playable spaces. Each tile has small triangles on all sides. If 2 pieces are laying attached to each other, the triangles form squares on the common sides. These squares are called "towers" and they are important to capture opposing pieces, since they represent the strength of attacking/defending tiles. Winner of the game is the player who is the first who can lay down all his 20 tiles on the board.
