The scores which may be made in course of play are as under:—
Pairs.—A player playing a similar card to the card last played by his adversary (as a king to a king, or a seven to a seven) is entitled to score two for a pair.[[14]]
Pairs-royal.—If the first player in the case last supposed can follow with a third card of the same description, he scores six for a pair-royal.
Double Pairs-royal.—If the second player replies with a fourth card of the same description, he scores twelve for a double pair-royal.
Sequences, or Runs.—Three or more cards of any suit but forming a regular numerical succession (as two, three, four; knave, ten, nine), count one for each card to the last player. The sequence need not be played in regular order, so long as the cards exposed for the time being form an unbroken series. Thus, suppose that A plays a five, and B a four. If A now plays either a six or a three, he is entitled to score a run of three (three points). We will suppose that he plays a three. If B can play either a six or a two, he will be entitled to score four; and if A can then add another card at either end, he will score five. Suppose, again, that A has played a five and a three, and B a two and a six. If A now plays a four, he is entitled to score five for the complete sequence. The highest number that can be scored
for a sequence is seven, for ace, two, three, four, five, six, seven. Ace, king, queen, do not count as a sequence.
Fifteen or Thirty-one.—A player whose card makes, with those already exposed, the number fifteen, scores two. If either player makes thirty-one, he scores two in like manner. If, when the cards on the table approach thirty-one, the player whose turn it is can go no further without passing that number, he says, "Go." His opponent then plays any other card or cards up to that limit. If they make thirty-one exactly, he scores two; if not, he scores one for "last card," i.e. the last card played. This (at five-card cribbage) terminates the hand.
The hand being over, the players, beginning with the non-dealer, proceed to "show," i.e. turn up their cards, and reckon how many points they may contain conjointly with the turn-up card, which is regarded as belonging, for this purpose, to the hand of each player, as also to the "crib" of the dealer. The first point noted is the fifteens they may contain, two points being reckoned for each, and the cards being combined in every possible way to make that number. Thus three fives and a ten or court card make (apart from their value under other aspects) four fifteens (technically spoken of as "fifteen eight"[[15]]), each of the fives forming one fifteen with the ten, and the three fives united forming another.
The next thing to be noted is the presence of any pairs, pair-royal, or double pair-royal. Thus, in the
case supposed, the player, after claiming "fifteen eight," would go on to say "and six for a pair-royal, fourteen."
