Visually, cribbage is known for its scoring board - a series of holes ("streets") on which the score is tallied with pegs (also known as "spilikins"). Scores can be kept on a piece of paper, but a cribbage board is almost always used, since scoring occurs throughout the game, not just at the conclusion of hands as in most other card games. Points are registered as having been scored by "pegging" along the crib board. Two pegs are used in a leapfrog fashion, so that if a player loses track during the count one peg still marks the previous score. Some boards have a "game counter", with many additional holes for use with a third peg to count the games won by each side.
There are several designs of crib board:
1) The classic design is a flat wooden board approximately 250 to 300 mm (10 to 12 in) by 70 to 80 mm (3 to 4 in) and 10 to 20 mm (0.4 to 0.8 in) deep. There are two sets of 60 holes (30 'out' and 30 'back') divided into 5 point sections, see picture above. A pegging-out hole in the middle at each end allows the board to be used in either direction. One player or team scores on one set of 60 holes and the other player or team scores on the second set. Different arrangements are made for three player games.
2) A relatively old design is that of an equilateral triangle with two rows of forty holes on each side. These boards did not generally include extra pegging-out holes or holes to count games.
3) A newer design has three or four rows of 120 holes with a pegging-out hole at the end and is often brightly coloured. It is best suited to games played to 121, though it can also be used for 61-point games.
4) Another common variation is based on features of the highest-scoring cribbage hand. The board takes the form of the number 29 (the highest possible score), with the pegging rows following the contour of the numbers "2" and "9". The design can sometimes include a background image of three fives and a Jack, with the fourth five offset the "perfect hand" giving that score. The count being 8 times 15 for 16 points, 6 pairs of 2 for 12 points and a matching "nobs" Jack (matching the cut card) for 1 totaling 29.
Because the crib board is a useful scoring device, players sometimes use it to keep score in other games, such as dominoes.
