Gin Score Calculator: what to know before playing
For a calm first round, focus on one decision. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. A clear plan starts with the current position. 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.
Build familiarity through play
Before making a move, check the cards in view. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed. Use another round to revisit a decision.
What you are aiming for
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. Take a moment to read the table.
The playing sequence
- 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.
