Cribbage (rules) - The Play

The play (often called pegging) starts with the player on the dealer's left and continues clockwise. Each player lays one card in turn onto the table so that it is visible, stating the cumulative value of the cards played. (For example, the first player lays a 4 and says "four", the next lays a 7 and says "eleven", and so on). Face cards are worth ten; Aces are worth one. Play must not exceed 31, so a player who cannot lay a card without bringing the total above 31 passes by saying "Go". The other players continue to lay cards in turn without exceeding 31 until no cards can be played. The last player to lay a card scores two points if 31 is reached exactly ("31 for two"); otherwise one point is scored, e.g., "29 for one", or "30 for one", etc. The one-point score is known as "One for the go", or simply the "Go". The count is then reset to zero and play resumes, starting with the player to the left of the last card played. Players with cards remaining repeat this process until all players' cards have been played.

In addition to scoring one or two points for the last card, players score points according to the following rules:

• fifteen-twos
  • two points for a cumulative total of exactly fifteen ("fifteen for two")
• runs
  • three points for completing a run of three cards, regardless of the order in which they are laid (a 6, then a 4, then a 5 is a run of three even though they were not laid in order)
  • four points for completing a run of four
  • five points for completing a run of five
• pairs
  • two points for laying a card of the same rank as the previous card, thus completing a pair
  • six points for laying a third card of the same rank (a "pair royal" or "trips")
  • twelve points for laying a fourth card of the same rank (a "double pair royal" or "quad")

If a card completes more than one scoring combination, then all combinations are scored. For example, if the first three cards played are 5s, the third one scores eight points: two for making 15, and six for a pair royal. Card combinations cannot span a reset; once the total reaches 31 (or a Go has been scored) and counting has re-started at zero, cards already played cannot contribute to runs or pairs.

Players choose when to lay each card in order to maximise their score according to the scheme shown below. The first player to reach 121 wins the game.
