Dart Rules for Shanghai

Number of Players:
Any number can play, it is sometimes played with a dozen or more players.

Numbers in Play: 1, 2, 3, 4, 5, 6, 7

Rules of Play:  Players take turns throwing at the numbers 1, 2, and so on, in sequence, until 7. They try to score as many points as possible per turn (using all three darts). Only darts hitting the number in play count for score. So, when the number 1 is in play, the highest score that can be achieved is three - if the player hits a 1 with each dart. However, when the number 7 is the number in play, the highest score could be a 21 - if the player hits 7 all three times. Obviously, as the game progresses, the score gets higher. There are two ways to win: either have the highest score at the end of the game or score a shanghai and win automatically. A shanghai is hitting the single, double and triple of the number in play.
