Do you know when a rock is out-of-play? It may seem obvious but there are some twists and turns. Here are the key points.

  1. If a stone is not released before it reaches the hog line at the delivering end, it is a violation and if declared by the offending team, the non-offending team shall remove the stone and replace all affected stones as close as possible to their original position.


(Ed. Note the mandatory wording. If you know you’re rock has not been released before the hog line, why not remove it from play immediately?  Good question; no good answer other than them’s the rules. Also, the hog line is not a guideline, to be observed or not, at the player’s whimsy.)


  1. A stone that has been touched (or burned) by the delivering team before it reaches the far hog line must be removed from play immediately.


  1. A delivered stone that does not come to rest fully over the far hog line shall be removed from play UNLESS it has stayed out of play because of having struck a stone in play. In this case the delivered rock stays where it came to rest and any subsequent rocks that strike that stone also remain in play.


  1. A stone which clearly crosses the back line is removed from play immediately.


(Ed. Note this is mandatory AND was changed from previous Rules that required the rock to come to rest; a rock could cross the back line but spin back into play. This change occurred in 2010. An interesting perspective on this from Bill Tschirhart in his blog “The Most Common Rule Violation Follow Up”, posted Feb. 4, 2014.)


  1. A stone that touches a sideline, hits a divider or comes to rest biting a sideline shall be immediately removed from play. If a stone in motion hits a stationary stone and a sideline or divider at the same time, the stationary stone shall be allowed to take its course as if it had been hit first.


(Ed.  Note there may be local rules in effect that players need to be alert to; e.g. at the Oshawa Curling Club, the sidelines between sheets 1 and 2 and 7 and 8 overlap. On these sheets, but only on these sheets, your sideline is the farthest one from the button.)


  1. A stone that rolls over in its course or comes to rest on its side or top shall be removed immediately from play.


(Ed. What happens if a stone is broken in play?  A replacement stone shall be placed where the largest fragment came to rest.)


Etiquette/Courtesy & Safety Tip


The delivering team’s players are primarily responsible for your rocks but the opposing skip or vice is also expected to co-operate and collaborate in keeping the game safe for all participants and protecting the ice, rocks, hacks and facility from damage. Protect the hacks and ice from being damaged by a rock colliding with the hack.


Stop the high hard ones from crashing into rocks that are out-of-play behind the back line.


Prevent running rocks or rocks set in motion from crossing the sidelines onto an adjacent sheet, displacing stationary stones and disrupting play.


Stop rocks from colliding with a non-alert player.  This can cause serious injury.


Practise safe curling. Be alert to not only what is happening on your sheet of ice but also to what is transpiring on adjacent sheets and keep out of the way of other players as you expect them to keep out of your way.


Play safe!
