Rules for Mixed Doubles Curling

A Mixed Doubles team consists of two players. For official USCA mixed doubles curling, the team must have one male and one female.

  1. 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.
  2. Games will be eight ends. If the score is tied after eight ends, play shall continue for the extra ends required to break the tie.
  3. Each team shall deliver five stones per end. 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.
  4. 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.
  5. Prior to the start of every end, one team shall place its "positioned" stone at the playing end of the sheet in one of two positions, designated A and 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. The team with the decision can choose either position for their stone.)
    • Position A: a guard stone bisected by the center line, at a point between the hog line and the front of the house. The teams shall determine the specific placement for Position A prior to the start of pre-game practice and that same placement must be used for the entire game.
    • 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.
  6. A coin flip will determine which team has the decision 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.
  7. 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 placing your stone in the house, you take the hammer.)
  8. 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.
