Knock with 5 deadwood against your opponent’s 22 and you score 17. Get undercut and they score the difference plus 25. The CasinoCalcs gin rummy calculator above scores each hand that way: pick who went down and how, type the deadwood, and it goes on the score sheet. When someone reaches 100 it adds the game bonus, the box bonuses and a shutout if there was one. It’s free and saves the game in your browser.

Gin rummy calculator: scoring a hand

Result Who scores Points
Knock, lower deadwood Knocker Difference in deadwood
Undercut (defender equal or lower) Defender Difference + 25
Gin (no deadwood) Player who went gin 25 + opponent’s deadwood
Big gin (all 11 cards melded) Player who went big gin 31 + opponent’s deadwood

Card values for deadwood: aces 1, number cards face value, jacks, queens and kings 10. You can type ‘3+4+10’ straight into a deadwood box and the calculator adds it. You can only knock with 10 or less deadwood, and it won’t let you score a knock above that.

End-of-game bonuses

A game goes to 100. Then the bonuses go on:

  • Game bonus: 100 to the winner
  • Box (line) bonus: 25 for every hand each player won
  • Shutout: if the loser won no hands, the winner’s total is doubled

Say you win 104 to 40, and you each won two hands. Add 100 and two box bonuses to yours, and two box bonuses to theirs: 254 to 90, so you’re up 164. House rules differ (some use 20 for gin and the box), so the bonuses are adjustable in the house rules box.

Deadwood, undercuts and when to knock

Knocking early with 8 or 9 deadwood is often right, because your opponent hasn’t had time to tidy their hand. Later in the hand, the undercut risk climbs. If you’d rather keep score for basic rummy or a family game, the rummy score sheet and the general card game score sheets are built for that.

Frequently asked questions

How do you score a knock in gin rummy?

The knocker scores the difference between the two players' deadwood. Knock with 5 against 22 and you score 17.

What is an undercut in gin rummy?

When the defender's deadwood, after laying off, is equal to or lower than the knocker's. The defender scores the difference plus an undercut bonus, usually 25.

How many points is gin?

25 plus the opponent's deadwood. Big gin, using all 11 cards, is usually 31. Your opponent can't lay off against gin.

What are the bonuses at the end of a gin rummy game?

The first to 100 gets a 100-point game bonus, each player gets 25 for every hand they won, and if the loser won no hands at all, the winner's score is doubled.
