Cribbage

Cribbage is a game in which each of two players is dealt a hand of six Cards. Each player then discards two of hissix cards to a four-card ``crib'' which alternates between players. After the discard, the top card in the remaining deckis turned up. Cards are then alternating played out by the two players, with points being scored for pairs, runs,cumulative total of 15 and 31, and playing the last possible card (``go'') not giving a total over 31. All face cards arecounted as 10 for the purpose of playing out, but the normal values of , , are used to determine runs. Aces are always low (). After all cards have been played, each player counts thefour cards in his hand taken in conjunction with the single top card. Points are awarded for pairs, flushes, runs, andcombinations of cards giving 15. A Jack having the same suit as a top card is awarded an additional point for ``nobbs.'' The crib is then also counted and scored. The winner is the first person to ``peg'' a certain score, as recorded on a``cribbage board.''

The best possible score in a hand is 29, corresponding to three 5s and a Jack with a top 5 the same suit as the Jack.Hands with scores of 25, 26, and 27 are not possible.
