It's easy to play and the rules are included in the game, but here is a quick review:
Aim with the mouse. Throw by holding the mouse down and release when the 'accuracy circle' is at its smallest. HINT: letting go early is better than late!
To when a leg of 501 darts, you must finish on a double. You will notice a little circle that appears on the board that helps you decide what to aim for. Also you'll see things like T20, T17, D12 in the top right - these are also hints - Treble 20, Treble 17, Double 12.
