Gin Score Calculator: instructions and practice
Work at your own pace. 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. Take a moment to read the table. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. Take the next action only when the current step is clear.
Fixed house bonuses of 25. It does not include line bonuses or a match-end bonus.
One thing to notice as you play
Treat this as a chance to practise one rule. 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 objective of a round
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. For a calm first round, focus on one decision.
Step by step
- 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.
The controls to know
Use the two numeric fields, then Calculate score. This tool uses whole numbers. Use another round to revisit a decision. Look at the complete hand before deciding.
Put the rules into context
A knock of 8 against 5 is an undercut: the defender receives 28. Gin against 18 earns the knocker 43. Take the next action only when the current step is clear.
Avoid this misunderstanding
Keep the active rule in mind. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. Return to the explanation when a decision is unclear.
