<P> Once the play is complete, each player in turn, starting with the player on the left of the dealer, displays his hand on the table and scores points based on its content in conjunction with the starter card . Points are scored for combinations of cards totalling fifteen, runs, pairs (multiple pairs are scored pair by pair, but may be referred to as three or four of a kind), a flush and having a Jack of the same suit as the starter card ("one for his nob (or nobs or nibs)", sometimes called the "right" Jack). A four - card flush scores four and cannot include the cut or starter; a five - card flush scores five . </P> <P> The dealer scores his hand last and then turns the cards in the crib face up . These cards are then scored by the dealer as an additional hand, also in conjunction with the starter card . Unlike the dealer's own hand, the crib cannot score a four - card flush, but it can score a five - card flush with the starter . </P> <P> All scores from 0 to 29 are possible, with the exception of 19, 25, 26 and 27 . Players may refer colloquially to a hand scoring zero points as a "nineteen hand". </P> <P> Muggins (also known as cut - throat) is a commonly used but optional rule, which must be announced before game play begins . If a player fails to claim her or his full score on any turn, the opponent may call out "Muggins" and peg any points overlooked by the player . </P>
