There is only one format for Curling under JAM Rules. It is described in its entirety below.
All Curling matches are approximately 2 hours in length. 8 ends are to be played within the 2 hours. Please arrive early to ensure you get the full use of your allotted sheet time. No new end may start with less than 10 minutes to go in your game. Regardless of when your game begins your game will always end on time to allow the succeeding games to begin at their scheduled time.
Time Keeping: Timekeeping will vary depending on the venue you are playing at.
East York Curling Club: If you’re playing without an official score clock the JAM Ambassador on site will be keeping track of time and will determine the end of your game. In this instance, you will receive a warning indicating the final five (5) minutes of your game and a final signal for the end of your game. Once the final signal occurs your game is over. You will also receive a warning at the 10-minute mark to indicate that teams shall not start a new end.
High Park Curling Club and St. George`s Golf and Country Club: There are no JAM staff members on-site during your game. Please designate one person to act as the timekeeper.
Teams are comprised of four (4) players on a sheet at once. A default will occur if any team cannot field a squad by 15 minutes after the official start time. A team of five people is allowed with either one person sitting out each end, or having two people on the team only throw one rock each.
Gender Numbers: There are no gender requirements for JAM Curling Leagues.
Defaults: Teams are comprised of four (4) players, however, a team can play with 3 players. A default will occur if any team cannot field the minimum requirement of players by 15 minutes after the official start time.
Exceptions: Captains may agree to waive the rules regarding minimum players, and should be decided before the game starts. IF IT IS AGREED THAT THE GAME COUNTS, IT COUNTS!
All Curling matches will take place on our assigned curling sheets.
All curling equipment will be provided at the Curling Club (brooms, rocks, etc). All players are responsible for bringing CLEAN indoor shoes. Boots, outdoor shoes, or large chunky shoes are not acceptable - players will not be allowed to play.
Teams are also responsible for keeping track of the score. Please designate one person to keep track of the score.
The following outlines the basis of the rules of JAM Curling Programs:
Free Guard Zone Rule:
(1) The free guard zone is the area between the hog line and the tee line, excluding the house. Interpretation: A stone which comes to rest biting or in front of the hog line after making contact with a stone in the free guard zone is considered to be in the free guard zone. A stone which comes to rest outside the house but biting the tee line is not considered to be in the free guard zone.
(2) Any stationary stone(s) belonging to the opposition that is located in the free guard zone shall not be moved to an out-of-play position by the delivering team prior to the delivery of the 5th stone of the end.
Penalty: A stone that is delivered prior to the 5th stone of the end that results in an opposition stone being moved from the free guard zone, either directly or indirectly, to an out-of-play position is an infraction which shall result in the delivered stone being removed from play and any other stone if moved being replaced as close as possible to its original position.
Interpretation: A delivered third or fourth stone of an end may hit an opposition stone(s) located in the free guard zone on to a stone(s) not in the free guard zone providing that any opposition stone originally located in the free guard zone remains in play. If this action results in an opposition free guard zone stone being moved to an out-of-play position, the penalty described above will apply. You may move your own stone from the free guard zone or remove your own stone from the free guard zone, providing you do not cause an opposition stone to be moved from the free guard zone to an out-of-play position. You may also raise your stone located in the free guard zone onto an opposition stone located in the house and remove it from play.

Regular Season Matches
Games can end in a tie during the regular season.
Playoffs Eligibility and Tiebreak
If a playoff game ends in a tie at the end of regulation time, a tiebreaker will be played to decide a winner. A draw to the button will be used to break a tie. The team whose rock is closest to the button will be deemed the winner.
