A practical guide to Gin Score Calculator
Look at the complete hand before deciding. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Return to the explanation when a decision is unclear. For a calm first round, focus on one decision. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. Use another round to revisit a decision.

Build familiarity through play
Take a moment to read the table. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed. The same rule applies on a phone and on a computer.
The challenge in front of you
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Check the relevant controls before continuing. A clear plan starts with the current position.
The order of play
- Enter the knocker’s deadwood from 0 to 10. Zero means Gin.
- Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed.
- Calculate the result. Gin scores 25 plus defender deadwood; an undercut scores 25 plus the difference.
- For an ordinary successful knock, the knocker scores only the positive difference.
How your actions work

A useful caution
Begin with the objective. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. The same rule applies on a phone and on a computer.
