Cribbage: Complete Rules, Scoring, and Strategy

Cribbage is a two-player card game — though playable with up to four — built around a scoring mechanism so distinctive it requires its own physical apparatus: a wooden peg board that players race across to reach 121 points. The rules are precise, the scoring vocabulary is unique, and the strategic depth is genuine enough that competitive cribbage has thrived in organized play across the United States for decades. What follows covers the complete rule set, every scoring combination, and the decision-making frameworks that separate competent players from sharp ones.

Definition and scope

Cribbage is a trick-adjacent counting game played with a standard 52-card deck and a cribbage board, typically configured for a race to 121 points (sometimes 61 in short games). It was formalized by English poet Sir John Suckling in the early 17th century — one of the few games in existence whose authorship is attributed to a named individual — though it evolved from the older game "Noddy." For a deeper look at how games like this developed over time, the history of card games traces the cultural lineage that produced cribbage and its relatives.

The game uses all 52 cards from a standard deck. Card values work as follows: Aces count as 1, numbered cards count at face value, and all face cards (Jack, Queen, King) count as 10. Suits are irrelevant for counting purposes, with one exception — the Jack's suit matters when scoring "nobs."

Each complete round consists of three phases: the deal and discard phase, the play phase (called "pegging"), and the show phase (hand counting). Points accumulate across all three, and the first player to peg past 121 wins — even mid-hand, mid-play.

How it works

The deal. The dealer shuffles and each player receives 6 cards. Both players discard 2 cards face-down into "the crib" — an extra hand belonging to the dealer, scored at the end of the round.

The cut. The non-dealer cuts the remaining deck. The dealer flips the top card of the bottom half face-up; this card is called "the starter" or "the cut card." If it's a Jack, the dealer immediately pegs 2 points ("two for his heels").

Pegging. Players alternate playing cards face-up, each announcing the running total. The total cannot exceed 31. Scoring during pegging:

1. Reaching exactly 15: 2 points
2. Reaching exactly 31: 2 points
3. Failing to reach 31 exactly but playing the last card before reset: 1 point ("Go")
4. Pairs: 2 points (three of a kind: 6, four of a kind: 12)
5. Runs of 3 or more cards played consecutively (in any order): 1 point per card in the run

The show. After pegging, players count their 4-card hands (plus the starter card as a shared fifth card). The non-dealer counts first — a meaningful rule, since the game can end during counting. The dealer then counts their hand, then the crib.

Scoring in the show uses these combinations:

1. Fifteens: Every combination of cards totaling 15 scores 2 points
2. Pairs: 2 points each
3. Runs: 3+ consecutive ranks score 1 per card
4. Flush: 4 cards of the same suit in hand score 4; if the starter matches, score 5 (crib flushes require all 5 to match)
5. Nobs: Holding the Jack of the same suit as the starter scores 1 point
6. Nibs: See the cut card rule above — that's the dealer's 2-point bonus at the cut

The theoretical maximum hand score is 29 points — a specific configuration requiring three Fives and the Jack of the fourth suit, with a Five as the starter.

Common scenarios

The "19 hand" is cribbage's running joke: a hand worth 0 points, since 19 is mathematically impossible to achieve. Experienced players announce a zero-point hand by saying "nineteen" with the resignation of someone who has been here before.

A double run of three — say, 4-4-5-6 — scores 8 points: two runs of three (6 points) plus the pair (2 points). A double-double run with two pairs, like 4-4-5-5-6, scores 16 points and is the kind of hand that ends games.

The flush rules create a contrast worth understanding: in the hand, 4 matching suits score 4; 5 matching suits (including starter) score 5. In the crib, a 4-card flush does not score — all 5 cards must match. This asymmetry is intentional and affects which cards players discard to the crib.

Decision boundaries

Discarding to the crib is where card game strategy fundamentals apply most directly in cribbage. When the crib belongs to the opponent, players discard cards that are least useful to an opponent's count — separating cards that form fifteens, avoiding pairs. When the crib belongs to the dealer, the logic inverts: feed it cards that combine well.

The pegging phase rewards hand management strategies built around keeping the count below 31. Holding a low card (Ace through 4) provides flexibility to continue sequences without busting. Leading a 4 is a classic opening — it cannot be paired to reach 8, from which an opponent could score 15 with a 7.

Compared to games like rummy, where the decision space is primarily about building sets before your opponent, cribbage forces constant dual-mode thinking: optimize the hand for the show and optimize card sequencing for pegging simultaneously, with an imperfect information constraint because the opponent's full hand is unknown. Understanding card game odds and probability deepens pegging decisions considerably — calculating the likelihood that a certain count will leave an opponent without a legal play is the kind of edge that accumulates across a long session.

The crib discard decision, the pegging lead, and the cut card outcome interact across every round. Skilled players weigh all three rather than optimizing any single phase in isolation.
