Except as modified or expressly provided herein, the rules of the United States Curling Association shall govern all play.

1. A legal team, other than for Men’s curling and the Women's All-American, shall consist of at least three (3) curlers, at least one (1) of whom must be a regular member of the team.
2. A legal team for Men’s Curling and the Women's All-American shall consist of a least three (3) curlers, at least two (2) of whom must be on the original roster of the team at the beginning of the Event.
3. A legal team for Mixed Curling shall also consist of at least one (1) male curler and one (1) female curler, and the throwing order must alternate genders. In situations where the gender composition of a team is unequal, the curler who is the sole gender may not throw in the lead position.

1. If a member of a team is unable to play, he or she must arrange for a substitute and notify the skip of the team.
2. To qualify as part of a legal team, a substitute must be arranged in advance of the night of play or be a curler who is not assigned to a team scheduled to play that evening and shows up in hopes of being a substitute. A player borrowed from another team on the night of play shall not be considered a valid substitute.
3. To allow a game to be played after a forfeit has been declared, teams may borrow a curler from another team. The borrowed curler is to be designated by the skip of the loaning team.
4. Except as required by another provision of these rules, a substitute is allowed to play any position.

1. All regular events shall be scored on a win-lose basis with the winning team receiving 1 point and the losing team receiving 0 points except as stated below.
2. In any event where there are successive draws, in order not to delay following draws, ties will not be played off and each team will receive 1/2 point.
3. In any event where there are no successive draws, ties will be played off with each curler delivering only one stone each to determine the winner. The team winning the last regular end will deliver the first stone in the extra end. If the tiebreaker end results in no points, the game is over and each team will receive 1/2 point.
4. All teams winning by forfeit will be considered winners and will receive 1 point.
5. A team which is not a legal team must forfeit to a legal team who will be considered the winner and will receive 1 point; the game may be played, but the forfeit score as above shall stand. If both teams are non-legal, a game may be played, but both teams shall be considered as forfeiting and no points shall be awarded.
6. The vice-skips shall sign the score sheets and deposit them in the place provided for the event.
7. Event winners are to be determined by the team with the most points. If multiple teams tie for the most points, the head-to-head results will determine the winner. After eliminating tied teams based on the head-to-head results, all remaining teams will be considered event winners.
8. In the situation where all teams in an event are not scheduled to play the same number of games due to bye weeks or other scheduling issues, the event chair should use their best judgment to determine event winners, with the assumption that more winners are better than fewer. Any tie-breaking rules for an event must be publicized prior to the start of the event or there shall be no tiebreakers allowed.
9. Event chairs are responsible for recording scores weekly, posting team rankings on the website, and determining the event winners upon conclusion of the event.

1. Teams must be ready to play at the scheduled time. A team not ready to play at the scheduled time shall forfeit 1 point and 1 end for the first full ten minutes delay, and for each additional ten minutes up to 30 minutes, and also deliver the first stone. After 30 minutes, the late team shall forfeit. A team may start with 3 players, and a tardy player may join at the start of the next end.
2. The sweeping motion shall be from side to side in front of the stone and shall clearly finish to the side of the stone.
3. A stone must be in motion before it can be swept. Warming the ice is illegal.
4. Behind the tee line, a team has first privilege of sweeping its own stone, but it must not obstruct or prevent its opponent from sweeping. It is unsportsmanlike to prevent an opposing player from sweeping an opposing stone behind the T-line.
5. All measurements shall be made by the vice skips, and no one else shall be allowed within 4 feet of the house during the measurement.

Games will be timed with the clock stating at the scheduled time for the draw (whether teams have commenced play or not). The bell will be sounded when the clock indicates 1 hour 40 minutes from the start time of the draw. Games in progress will then be allowed to complete the end being played plus one additional end. Everyone is asked to promptly exit the ice so it can be cleaned and readied for the next draw. The Bell Rule does not apply to draws that have no successive draws.

Any questions about these rules or their interpretation, except during the course of a game, shall be referred to and be answered by the Curling Chair. During the course of the game, questions shall be referred to the Event Chairman or a person designated by such Chair.
