All Fives

Each round each player has to score a total divisible by 5. And every divisible '5' counts one point. For instance 2, 8, 5 with a total 15, player can get 3 points as 15 divided by 5 is three.

There will be no points if

a. The round (3 darts) total scores is not divisible by 5

b. A player throws the 3rd dart and missed even though the previous 2 darts' score 4 is divisible by 5. The first player who gets scores of 51 will be the winner.
