Cribbage

Cribbage, or crib, is a card game traditionally for two players, but commonly played with three, four or more, that involves playing and grouping cards in combinations which gain points. Cribbage has several distinctive features: the cribbage board used for score-keeping, the eponymous crib, box, or kitty (in parts of Canada)—a separate hand counting for the dealer—two distinct scoring stages (the play and the show) and a unique scoring system including points for groups of cards that total fifteen. It has been characterized as "Britain's national card game" and the only one legally playable on licensed premises (pubs and clubs) without requiring local authority permission.

The game has relatively few rules yet yields endless subtleties during play. Tactical play varies, depending on which cards the opponent has played, assessing how many cards in the remaining deck of forty cards will help the hand you hold, and one's position on the board. Many games are decided by just a single digit points margin, with the edge going to the experienced players who understand the odds and their position on the board.

Luck-of-the-deal and the cut plays a role in the outcome of games, but over time experienced players will have an edge over novices.

History
According to John Aubrey, cribbage was created by the English poet Sir John Suckling in the early 17th century, as a derivation of the game "noddy". While noddy has become a historical, rarely-played game, cribbage has continued unchanged as a popular game in the English-speaking world. The objective of the game is to be the first player to score a target number of points, typically 61 or 121. Points are scored for showing certain jacks, playing the last card, for card combinations adding up to 15 or 31, and for pairs, triples, quadruples, runs and flushes.

Cribbage was played by American submariners, serving as a common pastime. The wardroom of the oldest active submarine in the United States Pacific Fleet carries on board the personal cribbage board of World War II submarine commander and Medal of Honor recipient, Rear Admiral Dick O'Kane, and upon the boat's decommissioning, the board is transferred to the next oldest boat.

Rules

Play proceeds through a succession of "hands", each hand consisting of a "deal", "the play" and "the show". At any time during any of these stages, if a player reaches the target score (usually 121), play ends immediately with that player being the winner of the game. This can even happen during the deal, since the dealer scores if a jack is cut as the starter.

Deal
The players cut for first deal, and the person who cuts the lowest card deals. The dealer shuffles and deals five or six cards to each player, depending on the number of players. For two players, each is dealt six cards; for three or four players, each is dealt five cards. In the case of three players, a single card is dealt face down in the centre of the table to start the crib. Once the cards have been dealt, each player chooses four cards to retain, then discards the other one or two face-down to form the "crib" (also called the box), which will be used later by the dealer. At this point, each player's hand and the crib will contain exactly four cards. The player on the dealer's left cuts the remaining deck, and the dealer reveals the top card, called the "starter" or the "cut". If this card is a jack, the dealer scores two points for "his heels" or "his nibs".

Play
Starting with the player on the dealer's left, the players each in turn lay one card face up on the table in front of them, stating the count—that is, the cumulative value of the cards that have been laid (for example, the first player lays a five and says "five", the next lays a six and says "eleven", and so on)—without the count going above 31. The cards are not laid in the centre of the table as, at the end of the "play", each player needs to pick up the cards they have laid.

Players score points during the play as follows:
15 – For causing the count to reach exactly 15 a player scores two points, then play continues.
Pair – Completing a pair (two of a kind) scores two points. 
Three of a kind is the same as three different pairs, or 6 points.
Four of a kind is 6 different pairs, or 12 points. 
A run of three or more cards (consecutively played, but not necessarily in order) scores the number of cards in the run.

If a player cannot play without causing the count to exceed 31, he calls "Go". Continuing with the player on their left, the other player(s) continue(s) the play until no one can play without the count exceeding 31. A player is obliged to play a card unless there is no card in their  hand that can be played without the count exceeding 31 (one cannot voluntarily pass). Once 31 is reached or no one is able to play, the player who played the last card scores one point if the count is still under 31 and two if it is exactly 31. The count is then reset to zero and those players with cards remaining in their hands repeat the process starting with the player to the left of the player who played the last card. When all players have played all of their cards the game proceeds to the "show".

Players choose the order in which to lay their cards in order to maximize their scores; experienced players refer to this as either good or poor "pegging" or "pegsmanship". If one player reaches the target (usually 61 or 121), the game ends immediately and that player wins. When the scores are level during a game, the players' pegs will be side by side, and it is thought that this gave rise to the phrase "level pegging".

Show
Once the play is complete, each player in turn, starting with the player on the left of the dealer, displays their own hand on the table and scores points based on its content in conjunction with the starter card. Points are scored for:
Combinations of cards totalling fifteen
Runs
Pairs (Multiple pairs are scored pair by pair but may be referred to as three or four of a kind.) 
Flush (A four-card flush scores four and cannot include the starter card; a five-card flush scores five.)
Having a jack of the same suit as the starter card ("one for his nob [or nobs or nibs]", sometimes called the "right" jack)

The dealer scores their hand last and then turns the cards in the crib face up. These cards are then scored by the dealer as an additional hand, also in conjunction with the starter card. Unlike the dealer's own hand, the crib cannot score a four-card flush, but it can score a five-card flush with the starter.

All scores from 0 to 29 are possible, with the exception of 19, 25, 26 and 27. Players may refer colloquially to a hand scoring zero points as a “nineteen hand”.

Muggins
Muggins (also known as cut-throat) is a commonly used but optional rule, which must be announced before game play begins. If a player fails to claim their full score on any turn, the opponent may call out "Muggins" and peg any points overlooked by the player.

Match
A match (much like tennis) consists of more than one game, often an odd number. The match points are scored on the cribbage board using the holes reserved for match points. On a spiral board, these are often at the bottom of the board in a line with 5 or 7 holes. On a conventional board, they are often in the middle of the board or at the top or bottom.

In a two-player game of cribbage, a player scores one match point for winning a game. Their opponent will start as dealer in the next game. If a player lurches (British) or skunks (US) their opponent (reaches 121 points before their opponent scores 91 points), that player wins two match points for that game. If a player double skunks their opponent (reaches 121 points before their opponent reaches 61), they score three or four match points for the game, depending on local convention. If a player triple skunks their opponent (reaches 121 points before their opponent reaches 31 points), they automatically win the match. Double and triple skunks are not included in the official rules of cribbage play and are optional. There are several different formats for scoring match points.

Cribbage board

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:
The classic design is a flat wooden board approximately 250–300 mm (10–12 in) by 70–80 mm (3–4 in) and 10–20 mm (0.4–0.8 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.
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.
A newer design has three or four rows of 120 holes in a "paperclip" shape (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.
A tournament long board is used in sanctioned tournaments in the American Cribbage Congress and consists of four rows of 60 pegs (two rows for each player), no number markings or five point segments, and only a mark indicating the skunk line.  Movement around the board starts on the outside and ends on the inside.  Players start and end in the same hole.
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 combinations of 15 for 16 points, 6 pairs of 2 for 12 points and a matching "nobs" jack (matching the cut card) for 1 totaling 29.

Each of the four 30-point divisions of the cribbage board (1–30, 31–60, 61–90, and 91–120) is colloquially called a "street".  Being at 15 points would be on first street, being at 59 points would be on second street, etc.
