Each player gets 2 spheres, 2 cylinders, 2 cubes and 2 cones in their colour. A random player starts.
When it is your turn, you can place a piece on the board, so long as there is not already an opponent's piece of the same shape in the same row, column or region.
The first player to place the fourth different shape in a row, column, or region wins the game. If a player cannot make a valid move, they lose.
