Gin Score Calculator: how a round works
Use the rule sheet as a reference. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. 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.
Bring this focus to a round
Look at the complete hand before deciding. 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.
Understand the aim
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Check the relevant controls before continuing. Look at the complete hand before deciding.
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.
How to use the controls
Use the two numeric fields, then Calculate score. This tool uses whole numbers. Check the relevant controls before continuing. A clear plan starts with the current position.
