General Rules

1. Teams will be responsible for pebbling and nipping their sheet prior to each game. Each player may throw two practice rocks on the playing sheet prior to game play.
2. The eleven teams have been divided into two round-robin pools. Everyone will play either 4 or 5 games, depending on which pool they're in. When the round-robin is done, the top two teams in each pool will move on to a single-elimination championship round. If necessary, tie-breakers will be used to determine top two (head-to-head, button draw).
3. Games will be eight ends. During the initial round-robin pool play, tied games are acceptable. Teams will receive 2 points for a win, 1 point for a tie, and 0 points for a loss. During the championship round, if the score is tied after eight ends, play shall continue for the extra ends required to break the tie.
4. Scoring is the same as in regular curling. The "positioned" stones placed at the beginning of each end are eligible to be counted in the scoring.
5. While the team is in the process of delivery, the non-delivering player may be anywhere on the ice surface of the team's sheet. After delivery, either or both players may sweep their delivered stone and any stones set in motion that belong to their team anywhere in front of the tee line.
6. One player of the non-delivering team may sweep defensively behind the tee line.

Rules specific to doubles play

1. Each team shall position one stone and deliver five stones per end (players may choose any 6 stones of the same color on the sheet). The player delivering the team's first stone of the end must also deliver the team's last stone of that end. The other team member shall deliver the team's second, third, and fourth stones for that end. The player delivering the first stone can change from end to end.
2. No stone in play, including the "positioned" stones and those in the house, can be moved to an out-of-play position prior to the delivery of the fourth stone of an end (the fourth delivered stone is the first stone that can remove any stone from play). If there is a violation, the delivered stone shall be removed from play, and any displaced stone(s) shall be replaced, by the non-offending team, to their positions prior to the violation taking place.
3. A coin flip will determine which team has the decision on stone position for the first end.
   • Following the first end, the team that did not score shall have the decision on the placement.
   • If an end is blanked (neither team scores), the team that delivered the first stone in that end shall have the decision on placement in the next end.
4. Prior to the start of every end, the team with the decision shall place its "positioned" stone in one of two positions, designated A or B. The opponent's "positioned" stone shall then be placed in whichever position (A or B) remains vacant. See Figure No. 1. (If a yellow stone is placed in position A, a red stone will be placed in position B, or vice versa. )
   • Position A: a guard stone bisected by the center line, at a point between the hog line and the front of the house. Ardsley ice has coins embedded in the ice. The stone shall be on the house side of the coin with the edge of the stone touching the coin.
   • Position B: a stone in the house in the back half of the 4-foot circle, bisected by the center line. The back edge of the stone is aligned with the back edge of the 4-foot circle.
   • Power Play: Once per game, each team, when it has the decision on the placement of the "positioned" stones, can use the "Power Play" option to position those two stones. See Figure No. 2. The in-house stone (B), which belongs to the team with the last stone in that end, is placed on either side of the house with the back edge touching the tee line at the point where the 8-foot and 12-foot circles meet. The "Power Play" option can not be used in extra ends.
5. The team whose "positioned" stone is placed in Position A (in front of the house) shall deliver the first stone in that end, and the team whose "positioned" stone is placed in Position B (in the house) shall deliver the second stone in that end. (i.e., Deciding whose stone goes in the house and whose is a guard also determines the hammer. By deciding to place your stone in the house, you take the hammer.)
