A. The Last Dart Winning Dart must stick.
B. The machine was displaying the Throw Darts message and all other rules were followed. Then, no matter if the machine fails to score, or scores incorrectly, the player/team will be credited with the win in that game. Example Players score is 24 at the beginning of their turn. Their first dart hits and sticks in the single 9 but does not register or score. Their second dart scores a single 15, leaving the player on 9. The third dart is then thrown in the single 9, but does not register or score. Since it was the Last Dart Winning Dart, that player/team wins the game.
A dart that sticks in the board but does not activate the electronic scoring may not be manually scored.
If there is any question to whether the machine is scoring or working properly, STOP THE GAME. Do not remove darts or activate the Player Change. The team captains must try to solve the problem. If they are unable to do so, they will need to call for service. If the situation cannot be resolved, play will need to be moved to an available board. Scores will be re entered and play will continue. In tournament play, a referee must be called to resolve the problem.
If a dart bounces off the board it is considered a dart thrown even if it does not score. It may not be thrown again.
If a dart is thrown before the Throw Darts message lights, the dart will not score and is considered a dart thrown. It may not be thrown again. .....
