How to play...
First click the button of the game you want to play, 301 or 501.
Then click the red ball to aim your shot. Release it when the pointer reaches the right direction. Do this again for the height. The dart will be thrown. You must finish with a double!
The outside ring doubles its value, the inner ring tripples its value. The red center gives you 25 points and the black center means 50 points.
