General
The board is a 26-inch playing surface with a surrounding 2-inch ditch, divided into quadrants and four scoring rings plus a central hole.
The Crokinole board consists of a 26-inch circular playing surface encircled by a 2-inch ditch. The surface is divided into four equal quadrants, each marking the shooting area for one player. The board also has four concentric scoring rings and a central hole: (1) Central hole – 20 points; (2) Inner ring, enclosed by 8 posts – 15 points; (3) Middle scoring ring – 10 points; (4) Outer scoring ring – 5 points; (5) Outer lip between the shooting/starting line and the edge of the playing surface – 0 points. Disks that fall or travel into the ditch are out of bounds and score 0.
General
A disk is shot by bracing the middle or index finger against the thumb and snapping it against the disk.
A Crokinole disk is shot by bracing the end of the middle or index finger against the thumb and snapping the finger against the disk to drive it across the playing surface. Once the flicking finger has moved the disk, the shot has been taken — even if the disk has only moved a fraction of an inch. There are no take-backs after any movement has occurred.
Restriction
Shots must be taken with the disk flat and touching the starting line within the shooter's assigned quadrant.
All shots must be taken with the disk lying flat and touching the starting line within the shooter's assigned quadrant. A disk may be placed on the quadrant line itself, but no more than halfway over. Only the shooter's shooting hand may touch the board during a shot. No other player may touch the board. No disk may be placed on the board until it is time to shoot it.
Restriction
The shooter must remain seated with at least one posterior cheek in contact with their chair throughout the shot.
One Cheek Rule: The shooter must remain seated with at least one posterior 'cheek' in contact with the chair at all times during a shot. Players' chairs may not be moved until the end of the round.
Restriction
Unshot disks must remain on the table in full view; they may not be held in players' hands.
Unshot disks should not be held in players' hands. They must remain on the table in full view of all participants at all times.
Special
When no opposing disks are on the board, the shooter must land in or touching the 15-point circle; failure removes all contacted disks.
If the board contains no opposing disks, the shooter may attempt to land a disk in the center 20-point hole. If the disk does not land flat in the 20-point hole, it must come to rest inside or touching the 15-point circle (the ring enclosed by the 8 posts). The shooter may aim for the center directly, or aim to knock their own disk(s) into or touching the 15-point circle, possibly landing one in the 20-point hole. If no disks come to rest in the specified area (20-point hole or touching/inside the 15-point circle), all disks contacted during the shot are removed to the ditch until the end of the round.
Restriction
When opposing disks are on the board, the shooter must contact at least one opponent's disk or their shot and any friendly disks it touched are removed.
If there are opposing disks on the playing surface, the shooter may attempt to strike an opponent's disk directly, or aim to knock a friendly disk into an opponent's disk. If no opposing disk is contacted during the shot, the shooter's disk is removed from the board along with all friendly disks it touched during the shot.
Scoring
A disk landing flat in the 20-point hole is immediately removed and reserved for the owner to score at round end.
Any disk which settles flat in the 20-point hole is immediately removed from the board and placed near the score box to be added to the owner's total in the scoring phase — even if the owner is the shooter's opponent. If a disk is knocked into the 20-point hole by an opponent's disk, the disk's owner (not the opponent who knocked it in) receives the 20 points. Important caveat: if the shooter was required to contact an opposing disk (because opposing disks were on the board) and failed to do so, a center-hole shot is instead removed to the ditch (scoring 0), along with any disks it touched.
