How to play

This is a game for two players. Players must take turns to click on a square of their choice. They may click on the same square many times, but only if it does not belong to their opponent. The object of the game is to rid the board of your opponent's colour.

When a square is clicked more than once, it fills up. A corner square is full when it has two dots in it, an edge when it has three, and a centre piece when it has four. If a player clicks on one of her squares while it is full, it will overflow and explode. The surrounding squares will immediately become hers, and a dot will be added.
