Each player has 21 tiles: 12 tiles with 5 squares, 5 tiles with 4 squares, 2 tiles with 3 squares, 1 tile with 2 squares and 1 tile with 1 square.
Players take turns in placing one tile onto the 20x20 board. The first tile for each player has to be placed in their corner of the board. Each following tile has to touch a corner of one of your previous tiles, but it must never share an edge. It may share edges with the opponents' tiles though.
If a player has no more possible move, they have to pass. The game is over when no player can place a tile.
For each player, the squares of all their tiles on the board are added up. Finishing a game with all stones placed on the board gives a 15 points bonus. If the monomino is placed last, you will get a 20 points bonus. The player with the most points wins.
