Know the Irregularities In Gin Rummy Gambling
New Deal There should be a new deal by the same dealer if a card is seen faced in the pack or is exposed in dealing, or if at any time both players are found to have an incorrect number of cards.
Incorrect Hand If after play has begun one player is found to have too few or too many cards, his opponent may require a new deal or may allow play to continue. In the latter case, the offender must correct his hand by discarding without drawing, or drawing without discarding, a sufficient number of times. He may not knock until the next turn after his hand has been corrected.
If the opponent is found to have an incorrect hand after a knock, he is charged 10 for each missing card, or all his cards (if more than ten) are counted; in either case, he cannot score for undercut. If knocker's hand is incorrect, see Illegal Knock below.
Exposed Card If in drawing a player sees any card to which he is not entitled, all such cards must be placed face up on the table. The offender may knock in his current turn only if he has a gin hand. Otherwise, play continues, and the nonoffender may in each succeeding turn take one of the exposed cards or the top of the discard pile; after the first occasion when he draws from the stock instead, the right to draw from the exposed cards goes to the offender; and after the offender has first drawn from the stock instead, any remaining exposed cards are inserted at random in the stock.
A card found faced in the stock after play has begun must be shuffled back into the stock. There is no penalty against a player for exposing a card from his hand.
Illegal Knock If the knocker is found to have a deadwood count of more than 10, opponent may accept the knock, or may require the offender to play on with his whole hand exposed. If the knocker is found to have an incorrect number of cards, opponent may demand a new deal, or may require the offender to play on with his hand exposed and to correct it by drawing without discarding or discarding without drawing. If the knocker can make his claim good by rearranging his cards into different sets, he may do so.
Looking Through Discard Pile The players may agree in advance that looking through the discard pile will be permitted. In the absence of such agreement, the discard pile must be kept squared so that only the top card is readable; a player who spreads it and so sights a covered card loses his next turn, opponent then having two turns in successions.
