<P> If all 10 cards in a player's hand fit into melds and thereby the player has no deadwood, he or she can choose to go Gin in which case the round ends and the player going Gin receives a Gin bonus of 25 points (or another established amount) plus any deadwood points in the opponent's hand . The defending opponent can only lay out his or her melds and cannot lay off any deadwood into the melds of an opponent that has declared Gin . A player can go Gin with a hand of three or fewer melds as long as all cards fit into a meld . Players can also have an 11 card gin, see Big Gin Variant below . </P> <P> Gin hands normally consist of 10 cards . However, if a player chooses to draw so that 11 cards fit into melds, he or she can declare Big Gin in which case the player receives a Big Gin bonus of 31 points (or another established amount, commonly 50 points instead of the standard 31 points, depending on rule set) plus any deadwood in the opponent's hand . </P> <P> Aces are scored at 1 point, face cards at 10, and all other cards are scored at their numerical values . The number of points awarded for bonuses may vary from region to region . No matter what the bonus amounts are, points are scored in Gin for the following: </P> <Dl> <Dt> Knock Points </Dt> <Dd> After a player knocks, and the lay offs are made, the knocking player receives a score equal to the difference between the two hands .

There is no chance to lay off when a player goes gin . </Dd> <Dt> Undercut (or underknocking) </Dt> <Dd> Occurs when the defending player has a deadwood count lower than or equal to that of the knocking player (this can occur either naturally or by laying off after a knock). In this case, the defender scores an undercut bonus of 25 points plus the difference in deadwood in the knocking player's hand . (In some rule sets, the bonus is only 10 or 20 points, or is not awarded in case of a tie .) </Dd> <Dt> Game Bonus </Dt> <Dd> Once a player has acquired 100 points (or some other agreed - upon number) the game is over, and that player receives a game bonus of 100 points (or another agreed - upon number). </Dd> <Dt> Line Bonus or Box Bonus </Dt> <Dd> Added at the end of the game . For every hand a player won during the game, 25 points is added to his or her score . </Dd> <Dt> Big Gin </Dt> <Dd> Prior to knocking, if all 11 cards in a player's hand form a legal gin, the player can retain the extra card as part of his or her hand, and is awarded 31 points plus entire count of deadwood in his or her opponent's hand . (In some rule sets players may be awarded 50 points or another established amount plus the entire count of deadwood in the opponent's hand) </Dd> <Dt> Shutout Bonus </Dt> <Dd> If a game is completed with the winner having won every hand, the points for each hand are doubled before adding the line bonus . </Dd> </Dl>
