Halve-It

In this game, each player begins with 40 points.  Each player takes it in turns to throw 3 darts at 15s.  Each 15 hit is added to the score.  However, if a player misses with all 3 darts, their score is halved - hence the name.  Odd numbered scores are rounded up.  Next players throw for 16s, doubles etc.  The winner is the player with the most points at the end of the game.
