1. Aim of the game
Each player starts with 501 or 301 points. The number of points collected while hitting a board with a dart is subtracted from the given player’s points. The winner is the player who scores exactly 0 points that way.
It is a double out game, which means that players must hit a double that makes their score exactly zero to win the game.
In case of a bust the player’s score from the previous turn is restored. There is bust if one of the following events arise:
- The player scores more points in the active turn, than his current score (subtracting would result in a negative score)
- The player has 1 point after subtracting (you cannot score 1 with double out)
- The player has 0 point after subtracting but violates the double-out rule
