Rules There are 16 pieces, each of which has 4 attributes: large or small, red or blue, square or circle, and with or without a hole. The game begins with first player choosing a piece for the second player to place on the board. The second player can place it anywhere and must then choose another piece for the first player. The game continues this way in turns. The game ends when there are 4 pieces in a line (row, column or diagonal) all of which have a common attribute (i.e, all small, all circular etc). The player to make the last move wins the game.
