A practical guide to Gin Score Calculator
Take a moment to read the table. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Check the relevant controls before continuing. Before making a move, check the cards in view. 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.
An idea for your next attempt
Use the rule sheet as a reference. 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.
Your objective
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. Before making a move, check the cards in view.
How to proceed
- 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.
