The initial score is either 301 or 501. First to reach zero, wins! Every turn each player throws 3 darts and substracts points. The inner ring in a number gives TRIPLE scoring and the outter ring gives DOUBLE points. BUT: the last dart must hit exactly a Double to win! Ie: if your final score is 18, you need to hit a Double 9 to win the game. Negative score Busts and you lose your turn!
