Step by step

1
The deal
Each player receives 10 cards. The rest form the stock pile; the top card is turned face up to start the discard pile.
2
Build melds
A meld is a set (3 or 4 cards of the same rank) or a run (3+ consecutive cards of the same suit). Cards not in a meld are your deadwood.
3
Draw and discard
On your turn draw one card - from the stock or the discard pile - then discard one card. Keep your hand at 10 cards.
4
Knock
When your deadwood counts 10 points or less you may knock to end the hand. Face cards are 10, aces are 1, others count their number.
5
Go Gin
Meld all 10 cards with zero deadwood and you have Gin - the best way to end a hand, with a 25-point bonus.
6
Race to 100
Points are scored after every hand. The first player to reach 100 points wins the match.

Scoring

Knock: Score the difference between your opponent's deadwood and yours.
Gin: Your opponent's full deadwood plus a 25-point bonus.
Undercut: If the opponent's deadwood is equal to or lower than the knocker's, the opponent scores the difference plus a 25-point bonus.
Super Gin: Gin Rummy Super's special bonus for the perfect hand - watch for it in the room rules.

Keep your deadwood low - fewer points mean faster wins.
Watch what your opponents pick up from the discard pile; it reveals the melds they are building.
Discard high cards you do not need early - do not hold on to what does not help you.
Knocking early is often better than waiting for Gin when the stock is running low.
