Take in turns with a friend, to click on white spaces to place your red/yellow piece. The sprite at the top tells you whose turn it is. As all the white circles change colour when you click them, to play properly, only click places that would be possible to go in a real game of connect 4. Reset all the pieces to white by clicking the green flag
