Glossary of curling

This is a glossary of terms in curling.

#s
During a game, sweepers might call out numbers. These numbers indicate how far the sweepers think the rock in play will travel. This system is relatively new to the game and is often attributed to the Randy Ferbey rink since they were the first major team to use the system, but it is not known whose idea it originally was. 1 to 3 indicates a rock in the free guard zone, 4 to 6 the rings in front of the tee line, 7 being on the button, and 8 to 10 the rings behind the tee line. Sometimes, 11 is used to indicate a stone thrown so that it passes through the house and out of play. With this system, the sweepers can communicate more effectively where they think the stone will end up or the skip can better tell the deliverer how hard to throw it.

#

 * 2 hammers to 1 : An endgame strategy based on maintaining hammer in the even ends of the last 3 ends of the game. If the team with hammer always scores (in other words, no blanks and no steals), then one team will have one more scoring opportunity than the other (hence "2 to 1").
 * 4-foot : The 4 ft circle in the house. It surrounds the centre area called the button. It is used as a visual aid only – there is no extra score for placing a stone within it
 * 8-foot : The 8 ft circle in the house. It is used as a visual aid only – there is no extra score for placing a stone within it; generally not actually painted – it appears as the empty space between the 12-foot and 4-foot rings
 * 12-foot : The 12 ft circle outermost in the house; a stone completely outside this circle cannot score

A

 * Across the face : On a hit, refers to the shooter hitting the object stone on the opposite side from where the broom was placed. Since this imparts less speed to the object stone and takes less speed away from the shooter, it is a very efficient way of making a tick. This is seldom used for normal hits since it is harder to execute, unless necessary because a guard prevents using the other turn
 * Anti-freeze : A very rare and extremely difficult shot in which a stone is delivered so that it will come to rest behind another stone already in play, created the same effect as if one stone had been frozen to the other
 * Anti-slider : Synonymous with gripper
 * Arena ice : Temporary curling ice made quickly on a hockey rink or the like, most often used by curling clubs without dedicated curling facilities; usually of lower quality than that of a dedicated facility, but when created for televised events or events with large numbers of spectators, the ice quality can rival or even exceed that of a dedicated facility
 * Arithmetically eliminated : WCF term for when a team runs out of stones
 * Around the horn : A double or triple where the shooter ends up coming back up the rings

B

 * Back 4 : The portion of the 4 foot ring behind the tee line
 * Back 8 : The portion of the 8 foot ring behind the tee line
 * Back 12 : The portion of the 12 foot ring behind the tee line
 * Back board : The border at the extreme ends of the sheet
 * Back end : A team's third and skip, considered as a unit.
 * Back-house weight : Delivery speed required for a stone to come to rest in the back half of the house
 * Backing : A stationary stone that can be used to stop the thrown stone from going any farther, thus allowing for a slightly heavy throw. Without backing, the shot will be harder since it requires perfect draw weight.
 * Back line : The line right behind the house. If a rock completely crosses the back line, it is removed from play
 * Back of the house : The portion of the house behind the tee line
 * Back ring : Synonymous with back 12
 * Barrier : A board or other object behind the hack, used to stop moving stones; referred to as "bumper" in Canada
 * Barrier weight : Delivery speed that should come to rest against the barrier behind the hack. Synonymous with board weight.
 * Besom : The traditional name for the device used to sweep ahead of a moving stone. A broom.
 * Bite : When a stone barely touches the designated line marking on the ice, e.g. "bite centre", "bite the four", etc.
 * Biter : A stone that barely touches the outside of the house, just biting the 12-foot ring
 * Bite stick / Biter bar : A piece of equipment used to determine whether or not a stone is a biter
 * Blank end : An end in which no points are scored; in regular play the team that has the hammer retains it for the next end. In skins games, the skin for a blanked end is carried over. To "blank an end" means to intentionally leave no stones in the house so as to retain the hammer.
 * Blanking an end : Deliberately creating a blank end for the purposes of retaining the last rock advantage for the next end of play
 * Blast : A shot delivered with heavy weight and high velocity. A blast is usually intended to remove many stones from play or is used to break up and move around clustered stones. "Playing the blast" into a large cluster of stones is often a last resort shot to get the rocks split up when there are no other viable shots available.
 * Board weight : Throwing a stone with enough speed that it will come to rest in an area just behind the hacks – about 6 feet behind the house. Synonymous with barrier/bumper weight.
 * Boating : A way to break in the ice by which one drags harnessed rocks over the recently pebbled sheet in order to break the beaks of the water droplets on the ice.
 * Bonspiel : Scots for league match, this is the term used for a curling tournament. Compare "spiel"
 * Bounce : A failed corner freeze where the shooter rolls open
 * Brier : The Canadian men's curling championship, held annually since 1927
 * Broom : An implement with which players sweep the ice to make a stone travel farther and curl less; though brushes have almost completely replaced brooms, the traditional name remains.

 * Brush / brushing : Broom / Sweeping
 * Bump : A short raise
 * Bumper : The barrier
 * Bumper weight : Synonymous with barrier/board weight
 * Buried : A rock that is hidden behind another rock, usually a guard, making it difficult for a curler to hit with a delivered rock. Also called "covered"

 * Button : The centre (bullseye) of the house; sometimes called the 1-foot circle

C

 * Calling the shot : When the skip holds the broom where they want the person delivering the stones to aim. When the skip is delivering, the vice-skip calls the shot
 * Cashspiel : A tournament with significant entry fees and large prizes, sometimes part of a charity event; despite the large prizes, cashspiels are not the premier events in curling
 * Catcher : A stone behind the tee line that may obstruct other stones from being removed
 * CCW : Counter Clockwise (turn of the stone from delivery)
 * Centre guard : A guard that is placed directly on the centre line, in front of the house; usually played by the team that does not have the hammer
 * Centre line : A line running lengthwise down the centre of the ice, used as a visual aid; some sheets do not have a centre line, or do not have one between the hog lines
 * Chip : A takeout that hits a rock at an angle
 * Chip and lie / chip and roll : When a played stone strikes the edge of another stone and moves to another position in play
 * Christmas tree : Series of rocks in the house arrayed from front to back in such a way that a corner of each successive rock is visible from the hack, angling out like the edge of a Christmas tree.
 * Chroming the rock : Grazing a stationary stone without significantly moving it; but enough to alter the path of the shooting rock
 * Circus shot : A flashy but low-percentage shot. Also Trick shot
 * Clean : To brush the ice lightly in front of a moving rock to remove any debris and ensure a correct line; less vigorous than a sweep
 * Club : The location of the curling rink; most players usually refer to it as "The Club"
 * Come-around : Any shot that curls around another rock
 * Coming home : Going into the final end
 * Control weight : A takeout shot that is slow enough that the sweepers have relative control over its curl; faster than board weight, but slower than normal takeout weight
 * Corner guard : A type of guard that is off to the side of the house; usually employed when a team has the hammer and needs to score multiple points
 * Counter : A stone in the house lying closer to the centre than any of the opponent's stones. Each counter scores one point at the completion of an end.
 * Cover : Protection given to a rock by a rock in front of it
 * Curl : Movement of a moving rock away from a straight line; as a verb, to play at curling
 * Curler : General term for player involved in a curling team; also known as a "soofter" in the UK
 * Curling : A team sport which involves sliding granite stones on ice and sweeping in front of them with brooms to direct them to desired placements
 * Curling club : Synonymous with club
 * Curling pin : A participation souvenir, generally worn on a sweater; there is a sub-culture at any major bonspiel built around trading pins. Most curling clubs and many tournaments produce one, and they are usually not awards
 * Curling stick : A device that permits a player to deliver a stone while standing upright; generally used by older players, these are legal in most games.
 * Cutter : A rock that has a tendency to finish more than other rocks.
 * CW : Clockwise (turn of the stone from delivery)

D

 * Dead buried : A rock completely covered by another rock (often a guard) such that no part is visible
 * Dead handle : Synonymous with no handle
 * Delivery : Process of throwing a stone
 * Deuce : Scoring 2 points in an end
 * Die! : A call given by the skip for the sweepers to stop sweeping a rock; a rock that dies is a rock that stops moving
 * Dish : State of a sheet of ice where the sides are slightly elevated compared to the center, so that a cross section of the ice would look like a cross section of a dish; this sometimes happens near the end of a week-long tournament because the pebbling motion tends to apply more pebbles to the side, while sweeping during games happens more often near the center and wears down the ice more in that region; when there is a dish, rocks will curl more towards the center and less away from the center
 * Double takeout / Double : A takeout shot in which two other stones are removed from play; a shot in which the delivered stone and one other stone are removed is not a double takeout
 * Doubles curling : A variation of curling played with 2 people per team and slightly altered rules. Most commonly seen as mixed doubles.
 * Drag : When two rocks are frozen, hitting the top rock at an angle creates a drag effect that affects the direction of the second rock; the friction between the two frozen rocks makes the first rock "drag" the second rock slightly towards the same direction; hitting the top rock on the right makes the bottom rock move more to the left while hitting it on the left makes it move more to the right
 * Draw : A shot that lands in play without hitting another stone out, as opposed to a takeout shot. Also refers to a game, e.g., “We have a draw at 7:00 p.m. tonight.”
 * Draw raise : A shot in which the played stone pushes a stone straight forward into the house
 * Drawmaster : Person who assigns teams to different sheets, sets starting times, assigns players to teams in casual play, etc.
 * Draw weight : Delivery speed required for a stone to come to rest in the house
 * Dump the handle (also Flip or Turn-Out/Turn-In) : During delivery of a stone, the thrower accidentally pushes the stone off-course with their turning motion; often the result of using the arm to shove the stone, and usually causes a missed shot

E

 * Easy : Command – called out by the skip to tell the sweepers to ease off their sweeping of a rock but to continue sweeping it lightly and slowly.
 * Eight-ender : An end where all eight stones score for one team – a very rare occurrence.
 * End : Similar to an inning in baseball; in an end, each team throws 8 rocks, 2 per player in alternating fashion; tournament style games usually run for 10 ends; games played at the club level usually run for 8 ends. Prior to the latter half of the twentieth century, a game consisted of 12 ends played in full.
 * Extra end : Equivalent to an extra inning in baseball; in the event of a tie after the prescribed number of ends, extra ends are played until the tie is broken.
 * Eye on the Hog : Technology in the rock handles to electronically detect hog line violations using magnetic strips under the hog lines and red/green LED indicators.

F

 * Fall : A defect in the ice which causes stones thrown in that area to curl negatively
 * Falling : As the stone is sliding down the sheet, it curls negatively, i.e., the opposite direction than it is supposed to
 * Finish : The amount of sideways movement in the last 3 meters (10 feet) or so of a rock's path; can be used as a verb ("it needs to finish") or a noun ("there's lots of finish in that spot")
 * Firm weight : Something more than Normal weight but less than Peel weight
 * Flash : To completely miss an attempted takeout; the rock passes through the house without touching any rocks at all
 * Force : When the team with hammer scores exactly 1 point on that end.
 * Fourth : The player throwing the last two rocks for a team; since the skip almost always throws the last two rocks, this term is rarely used
 * Free-Guard Zone : Area between the hog line and the tee line, excluding the house. Evolved from the Moncton Rule.
 * Free-Guard Zone Rule :The rule that states that an opponent's rock resting in the free-guard zone cannot be removed from play until the first five rocks of an end have been played
 * Freeze : A precise draw weight shot where a delivered stone comes to rest against a stationary stone, making it nearly impossible to take out
 * Front end : A team's lead and second, considered as a unit
 * Front-house weight : Delivery speed required for a stone to come to rest in the front half of the house
 * Front of the House : The portion of the house closer to the hog line
 * Front ring : Synonymous with top 12
 * Frost : Buildup that can occur on ice surfaces when there is excessive humidity in the air; tends to makes stones stop faster and curl less
 * Fun Spiel : Bonspiel oriented to recreational/fun play, often shorter duration games, and may have unusual formats

G

 * Game Clock : A clock that runs down and limits the amount of time a team can spend playing. Traditionally, the game clock ran from the end of the opposition's shot until the end of the team's clock, much like a chess clock. Now, thinking time is the standard.
 * Guard : A rock that is placed in front of another rock to protect it from being knocked out by the other team, or placed with the intent to later curl another rock around it and thus be protected; typically placed between the hog line and the very front of the house
 * Grand Slam of Curling : A series of eight premier men's and women's events that feature Canada's deepest and strongest curling fields
 * Gripper : A rubber or other material attached to a curling shoe to improve traction on the ice; also known as an anti-slider; see Slider

H

 * Hack : Similar to a starting block in track and field, the foothold device where the person who throws the rock pushes off for delivery
 * Hack weight : The weight required to deliver a stone in order that it travels to the hack at the far end
 * Hackweight takeout : A slower played takeout that, because of the reduced speed, curls more and therefore can reach opponent stones that are hidden behind a guard
 * Hammer : The last rock in an end – a huge advantage; the team with the last rock is said to "have the hammer"
 * Hammer efficiency: The percentage of non-blank ends in which the team who has hammer scores two or more points.
 * Handle : The part of the stone held by the player; used to describe the desired direction of rotation of the handle (and therefore the stone) upon release in a given delivery; "Losing the handle" refers to a rock which stops curling or which changes direction of curl while moving; See also no handle, reverse handle, straight handle.
 * Handshake : Each team traditionally shakes hands with each member of the opposing team at the end of a match as a sign of goodwill. Unlike other sports, curlers can, and are often encouraged to, forfeit the game early out of sportsmanship if the score is badly lopsided or if a team runs out of stones. To signal their forfeit, the losing team shakes the hands of the other team. This can simply be called "shaking", as in "the Smith team shook after 7 ends".
 * Hard! : Command – along with "hurry" – shouted by the skip to tell the sweepers to sweep harder and faster
 * Heavy : A stone that is thrown harder than required and will probably slide too far
 * Heavy ice : Slow ice on which stones take more initial force to travel a similar distance as on fast (keen) ice (see keen ice)
 * High side : The high side of a shooter in motion is the side that it is curling away from, i.e., the side outside the curve of the shooter's path. To "hit on the high side" is to hit the stationary rock off-centre on the side the shooter came from.
 * Hit : Any shot where the aim is to move another stone; the opposite of a draw
 * Hit and roll : A takeout rock that, after making contact with another rock, slides (rolls) into a designated area
 * Hit and stay : A takeout where the played stone stays in the spot where it made contact with the stationary stone; also called 'hit and stick' or a 'nose hit'
 * Hit weight : Another term for takeout weight
 * Hog : See "hogged rock"
 * Hog line (far) : The line which the stone must completely cross to be considered in play
 * Hog line (near): The line by which the stone must be clearly and fully released by the thrower
 * Hog line violation : Failure to release a stone before crossing the near hog line; a stone in violation is immediately removed from play
 * Hogged rock : A shot that comes to rest short of or on the far hog line and is removed from play. May also refer to a stone that is removed from play due to a hog line violation.
 * Hogger : See "hogged rock"
 * House : The three concentric circles where points are scored
 * Hurry! : see hard! (often said together: "hurry hard!")

I

 * Ice (more, less, too much, not enough) : Adjustment to the crosswise distance between the skip's broom and the desired target area; for example, a player who feels that the skip's broom is too close to the target might request "more ice"
 * Icemaker / Ice technician : Person who is responsible for maintaining the ice; duties include, but are not limited to, pebbling and scraping the ice
 * In-off : A shot where the delivered stone hits another stone near the outer edge of the sheet at an angle, making the shooter roll into the house; one of the most difficult curling shots, usually done as a last resort when there are no other options
 * In-turn : A shot in which the handle of the stone is rotated across the body (the elbow is rotated "in" to the body); for a right-handed thrower, an in-turn is clockwise, and the opposite for a lefty
 * Inside : Another term for narrow

J

 * Jam : A takeout that collides with a catcher

K

 * Keen ice : Fast ice on which stones travel greater distances with less force than required for heavy ice (see heavy ice)
 * Kizzle kazzle : A delivered stone that is intentionally wobbled to compensate for water, slush or snow on the ice surface

L

 * Lazy handle : When the rotation of a stone is very slow, i.e., less than one full rotation during the stone's slide; often the result of thrower error, they will usually curl more than a properly delivered stone; may turn into a No Handle or Reverse Handle
 * Lead : The player who throws the first two rocks for a team
 * Lie / Lies / Lying : The count of the number of stones of one colour closest to the centre of the button, closer than the innermost stone of the other colour. When a team "lies X" or "is lying X", that number of its stones are, at that moment, closer to the button than any opposition stone; were the end to finish then, the team would score that number of points.
 * Line: The path of a moving stone; a 'good' line indicates it is headed where it was intended to go; a 'bad' line has deviated
 * Light : A stone that is not thrown hard enough
 * Little rocks: Many clubs offer a Little Rocks program for children, with rocks that are roughly half the weight of regular 44 lb. rocks. Curlers generally move onto full-sized rocks around the ages of 10 to 12.
 * Losing the handle : A rock that is "losing the handle" refers to a rock which loses its rotation or which reverses its rotation while moving
 * Lost turn : Synonymous with no handle
 * Low side : The low side of a shooter in motion is the side that it is curling toward, i.e., the side inside the curve of the shooter's path. To "hit on the low side" is to hit the stationary rock off-centre after the shooter crosses its face.
 * LSFE : Last Stone in the First End; in every other end, the last stone (or hammer) is determined by the scoring in the previous end. In the first end, some other system (coin toss, draw contest, record comparison) must be used to determine the advantage of the hammer.

M

 * Manitoba tuck : A type of delivery, mostly found in Manitoba, where the body is kept very low to the ground and the leading leg is tucked underneath the body and to the side; this type is delivery is particularly efficient for hits but makes draws slightly tougher to execute, with the shoulders not being as straight and the eyes being closer to the ice
 * Mate : The player who discusses strategy with the skip behind the house and holds the broom while the skip throws their rocks; usually plays third; also known as vice-skip or vice
 * Measure stick : Equipment used to determine which of two or more stones is closest to the centre when they are too similar to know with visual inspection
 * Mixed team:A team composed of two men and two women with the throwing order alternating genders. Also known as True mixed. The highest level competition for mixed teams is the World Mixed Curling Championship.
 * Mixed doubles : A variation of curling played with 2 people per team, one man and one woman, and slightly altered rules.

N

 * Narrow : A stone delivered off the broom too close to the desired target and therefore likely to curl past it
 * Negative ice : A shot in which the player curls the stone in the opposite direction in which the stone is expected to curve, due to significant defects in flatness of the ice surface; for example, if the curvature of the ice causes all stones to drift sharply to the right, a skip may request the shooter to aim to the left of the desired location and curve the stone to the left as well.
 * Never : Called as the rock is sliding down the sheet to indicate the stone needs to curl and the sweepers should stay off the rock
 * Nice weight : A term used by some Manitoba teams, similar to control weight
 * No handle : A rock delivered without a turn, usually done in error; stones thrown without a handle often follow an unpredictable path
 * No-tick rule : A rule prohibiting stones from being ticked off the centre line for the first five stones of an end (see Free-Guard Zone Rule); only used in some competitions
 * Normal weight : Normal takeout weight; faster than control weight, but slower than peel
 * Nose: The point on a rock closest to the thrower. A "nose hit" would be hitting the rock at this point, avoiding a roll.

O

 * Off! : A call given by the skip for the sweepers to stop sweeping a rock
 * Off the broom : An incorrectly aimed shot; opposite of on the broom
 * Open : A rock that is not obscured by another rock from the thrower's perspective; a skip will often ask the thrower how "open" a certain rock appears from the hack, with the rock being totally open, partially obscured (such as "half open") or completely covered; also, a term for any shot not involving going around a guard: an open takeout, an open draw, etc.
 * On the broom : A correctly aimed shot that starts out directly at the broom held by the skip; opposite of off the broom
 * Out of stones : A situation in which a team that is behind in the score no longer has enough stones between those in play and those yet to be played to make up the deficit; the outcome is now certain, and the game usually ends with a handshake once a team is out of stones.
 * Outside : Another term for wide
 * Out-turn : A shot in which the handle of the stone is rotated away from the body – the elbow is rotated "out" from the body; for a right-handed thrower, an out-turn is counter-clockwise, and the opposite for a lefty

P

 * Pancake : A rock
 * Pebble : Small droplets of water intentionally sprayed on the ice that cause irregularities on the surface, allowing the rocks to curl. Also a verb; the action of depositing water droplets on the ice, as "to pebble the ice between games"

 * Peel weight : A stone delivered with a heavy takeout weight
 * Pick : When a rock's running surface travels over a foreign particle such as a hair, causing the rock to deviate from its expected path, usually by increasing friction and thereby the amount of curl

 * Raise takeout : A shot in which the delivered stone bumps a second stone which in turn knocks a third stone out of play. Also called a runback
 * Reading the ice : When a curler considers how the condition of a sheet of ice will influence the path of a thrown stone, similar to how a golfer reads the undulations and texture of a green before determining where and how hard to hit a putt
 * Reverse handle : When a stone is thrown with a particular turn, but it eventually stops and begins to rotate in the opposite direction; usually the result of a pick or poor ice conditions. Sometimes it may even reverse twice in one shot, creating unpredictable shots that follow an S-shaped path.
 * Right off! : A call given by the skip to tell the sweepers to neither sweep nor clean the rock; as compared to off!, which tells the sweepers to stop sweeping but not necessarily to stop cleaning
 * Rings : The house
