Cribbage is scored during the play of the hand, as well as at the end. This scoring system applies to two-handed play.
Scoring During Play
Peg two and say "fifteen two" if you play a card that brings the total to 15.
Peg two if you play cards that bring the total to 31.
Peg two for a pair if you play a card that is the same rank as the preceding card.
Peg six for a pair royal if you play a third card that is the same rank as the preceding two cards.
Peg 12 for a pair royal if you play a fourth card that is the same rank as the preceding three cards.
Score for a run if you play the last card in the run.
Score for all possible combinations of cards.
Score two points for any combination adding up to 15. Score eight points if you have a king, a queen and two 5's in your hand.
Score two points if you have a pair, six points if you have three of a kind and 12 points if you have four of a kind.
Score three for a run of three cards in consecutive order (regardless of suit).
Score four points if you have a flush or a hand in which all the cards are the same suit.
Score five points if you have a flush and the start card was the same suit.
Score one point ("one for your knob") if you have a jack in your hand that is the same suit as the start card.
Win the game when you score 121 points or more.
