How to play Gin Rummy

Gin Rummy is a fast two-player card game about building melds and minimising the deadwood you're stuck holding. First to 100 points across as many hands as it takes wins the match.

Melds

A set is three or four cards of the same rank. A run is three or more consecutive cards in the same suit. Every card you meld no longer counts against you.

Your turn

Draw one card — either the top of the stock or the top of the discard pile — then discard one card from your hand of 11 back down to 10.

Knocking

If your unmelded deadwood totals 10 or less, you may knock instead of discarding normally. Going out with 0 deadwood is a gin, worth a 25-point bonus.

Laying off

When your opponent knocks (but doesn't gin), you may lay any of your own deadwood cards off onto their melds, shrinking your deadwood before scoring.

Tips from the table

  • Deadwood value: aces count 1, face cards count 10, everything else is face value.
  • If your deadwood ends up equal to or lower than the knocker's after laying off, you score the undercut — the difference plus a 25-point bonus.
  • Hold cards that are one away from a run or set rather than isolated high cards.
  • Discard high, isolated cards early; they're expensive deadwood if you get stuck holding them.

Gin Rummy scoring reference

Aces count 1, face cards count 10, and every other card counts its number. Knock with 10 deadwood or less and score the difference between the two deadwood totals. Gin — zero deadwood — adds a 25-point bonus and the opponent cannot lay off. An undercut, where the defender ends level or lower, scores them the difference plus 25.

Match scoring

Games run to 100 points. At the end, the winner adds 100 for the game, 25 per hand won as a box bonus, and doubles everything if the loser never scored — a shutout, or schneider.

Variations

Oklahoma Gin sets the knock limit to the value of the first upcard, so an ace means only gin can go out. Hollywood Gin scores three games at once. Straight Gin removes knocking entirely: you must reach gin to go out.

Frequently asked questions

Can an ace be high in Gin Rummy?
No. Aces are always low, so A-2-3 is a valid run but Q-K-A is not.
When can you knock?
Any turn where your deadwood after discarding totals 10 points or less.
What is laying off?
Adding your deadwood cards onto the knocker's melds to reduce your count. It is not allowed when the knocker has gin.
