The game rules are the same as a standard game of 501 darts. You must score points to reduce your remaining score from 501 to zero in as little darts as possible. You must also checkout on the double or the bullseye.
Instructions: To throw your darts press the blue button located in the top right hand corner of the board (or press the space bar). You must press the button twice. Once for the horizontal co-ordinates and once for the vertical coordinates.
