Gin Rummy Rules
Setup
Gin Rummy is usually played by two players with a standard 52-card deck. Deal ten cards to each player. Place the rest face down as the stock and turn one card face up as the discard pile.
Goal
Your goal is to group cards into melds and reduce deadwood. A meld is either a set of three or four cards with the same rank, or a run of three or more consecutive cards in the same suit.
Turn Order
On each turn, draw one card from either the stock or the discard pile. Then discard one card face up. You always end the turn with one discard unless the hand ends.
Deadwood
Cards not used in a meld are deadwood. Aces count 1, number cards count their number, and jacks, queens, and kings count 10. Lower deadwood means a stronger hand.
Knocking
You may knock after discarding when your deadwood is 10 points or lower. The hand ends and both players compare deadwood. The lower deadwood hand wins the difference.
Going Gin
If all your cards fit into melds after your discard, you have zero deadwood and go gin. Gin scores the deadwood difference plus a bonus.
