Each leg begins with a "cork" which determines which team begins the game. The home team has the choice of throwing for the cork first or second in thr first game. One dart by each team is then thrown for the bull. The player throwing the dart closest to the center of the board wins. In the case of a tie, or if it is not clear which dart is closest, the cork will be re-thrown, with the player who shot first throwing second, until one player wins. The second shooter has the option of requiring that a single or double bull be pulled. A double bull beats a single bull. Both darts in either the single bull or the double bull is a tie. In any doubles or team event, the player throwing the cork has the option of allowing a teammate to start the game.
For game 2 - the loser of game 1 has the option of going first or second on the cork.
For game 3 - the loser of game 2 has the option of going first or second on the cork.
For Chicago matches - the loser of the first game must choose the second game, he/she may choose the game before or after the cork is thrown for game 2.
In "01" games, the player (or team) starts with a prescribed number of points and the aim is to reduce the score exactly to zero, finishing with a double. In 301, the player must also start with a double, no score being counted until the initial double is thrown. It is usually customary that only one person per team is required to double in for the entire team. In other "01" games, no double is required to start scoring, unless provided for in the format of that division. The inner bull (double bull) is scored as 50 points, and the single bull is scored as 25 points. If a player busts (reduces the score to 1, less than zero, or to zero without hitting a double), the score reverts to what it was before that turn. If both captains agree before the match, and both teams have had 5 rounds at the double 1, the cork rule may be used to determine the winner of the contest.
The scorekeeper, if any, can tell a player what amount is left to attain or what has been scored with the darts thrown. It is the player's total responsibility to throw at the right numbers. If he is told what to shoot by anyone and it is the wrong number, the darts stand as thrown, and the score actually thrown is counted. Once the final double has been thrown, the game is over and any darts thrown afterward do not count.
In Cricket, only the numbers 20 through 15 and the Bull are used. The team closing all numbers and the Bull (innings) without being behind in points wins the game. An inning is closed by scoring three hits in that inning. A hit in the double scores two and the triple scores three. All hits in an inning beyond those required to close the inning will score the value of the number (25 for Bulls) in points unless your opponent has also closed that inning. Points cannot be scored in innings that are closed by both teams. Cricket will be "slop" (all hits in live innings count), unless both captains have agreed otherwise.
Spanish is identical to Cricket except only the numbers 20 through 10 are used and Spanish is always "call"; the player must declare which number he is throwing at and hits in other numbers do not count. Gentlemen's call may be played with the consent of both captains, however, it is strongly suggested that a verbal call be made when shooting at the 15-10 and 14-11 beds if both innings are alive.
Minnesota is played with slop cricket numbers, along with 3 in a bed, triples, and doubles. Once the 3 in a bed is closed, any additional beds, if taken for score, are recorded as the total amount thrown (80, 140, etc.). This is a "slop" game like Cricket.
The foul line will be strictly enforced, and a player must have both feet behind the front edge of the foul line. If a player has one or both feet over the foul line in the judgment of both captains, the score for that turn will not count. A violating player must be warned immediately. Repeated violations will be grounds for protest.
