Rules of curling
Sheet
The sheet is an area of ice, carefully prepared to be as flat and level as possible, 45 to 46 m in
length by 4.4 to 5.0 m in width.
Two hacks are placed on the hack line, on opposite sides of the centre line, with the inside edge
of each hack 7.62 cm from the midpoint of the centre line. The width of each hack shall not
exceed 15.24 cm. The hack is attached to suitable material, and the inside edge of that material
is placed on the inside edge of the hack line so that the hack does not extend more than 20.32
cm in front of the hack line.
General
Curling match consists of 10 rounds. Each of these two teams has eight stones. In the case of a
draw after 10 rounds, they play more as long as one of the team won.
Stones
A curling stone is of circular shape, having a circumference no greater than 91.44 cm, a height
no less than 11.43 cm, and a weight, including handle and bolt, no greater than 19.96 kg and no
less than 17.24 kg.
Team
A team is composed of four players. Each player delivers two stones, in consecutive order in
each end, while alternating with an opponent.
A team declares its delivery rotation, and the skip and vice-skip positions, prior to the start of a
game and maintains that rotation and those positions throughout that game subject to
During the process of delivery the players take stationary positions along the sidelines between
the courtesy lines. However:
- the skip and/or vice-skip may take stationary positions behind the back line at the playing end,
but must not interfere with the choice of place of the skip or vice-skip of the delivering team.
- the player who is to deliver next may take a stationary position to the side of the sheet, behind
the hacks, at the delivering end.
The non-delivering team players must not take any position, nor cause any motion, which could
obstruct, interfere with, distract or intimidate the delivering team.
Delivery
Right-handed deliveries are delivered from the hack on the left of the centre line and left-
handed deliveries are delivered from the hack on the right of the centre line. A stone delivered
from the wrong hack is removed from play, and any displaced stones are replaced to their
original positions by the non-offending team.
A stone must be clearly released from the hand before it reaches the hog line at the delivering
end. If the player fails to do so, the stone is immediately removed from play by the delivering
team.
If a hog line violation stone is not immediately removed and strikes another stone, the delivered
stone is removed from play by the delivering team, and any displaced stones are replaced to
their original positions by the non-offending team.
A stone is in play when it reaches the tee line at the delivering end. A stone that has not reached
the tee line at the delivering end may be returned to the hack and redelivered.
All players must be ready to deliver their stones when their turns come, and not take an
unreasonable amount of time to play.
If a player delivers a stone belonging to the opposing team, that stone is allowed to come to
rest, and is then replaced by a stone belonging to the delivering team.
If a player delivers a stone out of proper rotation, the end continues as if the mistake had not
occurred. The player who missed a turn delivers the last stone for that team in that end. If it
cannot be determined which player delivered out of proper rotation, the player who delivered
the first stone in the end for that team delivers the last stone for that team in that end.
If a player inadvertently delivers too many stones in one end, the end continues as if the
mistake had not occurred and the number of stones allocated to the last player of the offending
team shall be reduced accordingly.
If a team delivers two stones in succession in the same end:
- the second stone is removed and any displaced stones replaced to their original
positions by the non-offending team. The player who delivered the stone played by
mistake, redelivers it as the last stone for the team in that end;
-
should the infraction not be discovered until after the delivery of a subsequent stone,
the end is replayed.
Free Guard Zone (FGZ)
A stone that comes to rest between the tee line and the hog line at the playing end, excluding
the house, is deemed to be within an area designated as the FGZ. Also, stones that are in play,
on or before the hog line, after striking stones in the FGZ, are deemed to be in the FGZ.
If, prior to the delivery of the fifth stone of an end, a delivered stone causes, either directly or
indirectly, an opposition stone to be moved from the FGZ to an out-of-play position, then the
delivered stone is removed from play, and any displaced stones are replaced to their original
positions by the non-offending team.
Sweeping
The sweeping motion is in a side-to-side direction (it need not cover the entire width of the
stone), deposits no debris in front of a moving stone, and finishes to either side of the stone.
A stationary stone must be set in motion before it can be swept. A stone set in motion by a
delivered stone, either directly or indirectly, may be swept by any one or more of the team to
which it belongs anywhere in front of the tee line at the playing end.
A delivered stone may be swept by any one or more of the delivering team anywhere in front of
the tee line at the playing end.
No player may sweep an opponent’s stone except behind the tee line at the playing end, or start
to sweep an opponent’s stone until it has reached the tee line at the playing end.
Behind the tee line at the playing end, only one player from each team may sweep at any one
time. This may be any player of the delivering team, but only the skip or vice-skip of the non-
delivering team.
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.
If a sweeping violation occurs, the non-offending team has the option of allowing the play to
stand, or of placing the stone, and all stones it would have affected, where they would have
come to rest had the violation not occurred.
If a moving stone is touched, or is caused to be touched, by the team to which it belongs, or by
its equipment, the touched stone is removed from play immediately by that team.
If a moving stone is touched, or is caused to be touched, by an opposition team, or by its
equipment, or is affected by an external force:
- If the stone was the delivered stone, it is redelivered
-
If the stone was not the delivered stone, it is placed where the team to which it belongs
reasonably considers it would have come to rest had it not been touched.
Scoring
The team gets one point for its stone, which is closer to the center of the house from the nearest
opponent’s stone.
Only the stones found in the home can stipple. If at the end of the round, it is not possible to
decide which stone is closer to the home, this round ends in a draw 0:0.
In case of any doubt, the judge has the final say. His decision may be appealed to the referee
the competition, whose decision is final.
During the curling matches are not allowed to smoke cigarettes and use offensive language.
