An introduction to playing Gin Score Calculator
Keep the active rule in mind. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. The same rule applies on a phone and on a computer. Treat this as a chance to practise one rule. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. The same rule applies on a phone and on a computer.
Fixed house bonuses of 25. It does not include line bonuses or a match-end bonus.
A focus for your next round
For a calm first round, focus on one decision. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed. Take the next action only when the current step is clear.
The challenge in front of you
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. The same rule applies on a phone and on a computer. Look at the complete hand before deciding.
How a round unfolds
- 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.

One detail worth checking
