The game is played by two players, each receiving ten cards.Deck:
Standard 52-card deck is used (without Joker).Cards in each suit rank, from low to high:
Ace 2 3 4 5 6 7 8 9 10 Jack Queen King.The cards have values
Number cards are worth their index value.
King, Queen, Jack are 10 points
Ace is 1 pointsObject of the Game
The object of the game is to collect a hand where most or all of the cards can be combined into sets and runs and the point value of the remaining unmatched cards is low.
A card can belong to only one combination at a time - you cannot use the same card as part of both a set of equal cards and a sequence of consecutive cards at the same time. For example if you have ♦ 7, ♠7, ♥ 7, ♥ 8, ♥ 9 you can use the ♥ 7 either to make a set of three sevens or a heart sequence, but not both at once. To form a set and a sequence you would need a sixth card - either a ♣ 7 or a ♥ 10.
Note that in Gin Rummy the Ace is always low. A-2-3 is a valid sequence but A-K-Q is not.
A normal turn consists of two parts:
For the first turn of the hand, the draw is done in a special way. First, the person who did not deal chooses whether to take the turned up-card. If the non-dealer declines it, the dealer may take the card. If both players refuse the turned-up card, the non-dealer draws the top card from the stock pile. Whichever player took a card completes their turn by discarding and then it is the other player's turn to play.Knocking
You can end the play at your turn if, after drawing a card, you can form sufficient of your cards into valid combinations: sets and runs. This is done by discarding one card face down on the discard pile and exposing your whole hand, arranging it as far as possible into sets (groups of equal cards) and runs (sequences). Any remaining cards from your hand which are not part of a valid combination are called unmatched cards or deadwood. and the total value of your deadwood must be 10 points or less. Ending the play in this way is known as knocking, presumably because it used to be signalled by the player knocking on the table, though nowadays it is usual just to discard face down. Knocking with no unmatched cards at all is called going gin, and earns a special bonus.Lay off
he opponent of the player who knocked must spread their cards face-up, arranging them into sets and runs where possible. Provided that the knocker did not go gin, the opponent is also allowed to lay off any unmatched cards by using them to extend the sets and runs laid down by the knocker - by adding a fourth card of the same rank to a group of three, or further consecutive cards of the same suit to either end of a sequence. If a player goes gin, the opponent is not allowed to lay off any cards.
