The Gin Score Calculator playbook
Before making a move, check the cards in view. 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. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. Return to the explanation when a decision is unclear.
Fixed house bonuses of 25. It does not include line bonuses or a match-end bonus.
A small practice goal
A clear plan starts with the current position. 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.
Your goal
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. Look at the complete hand before deciding.
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.
Making selections and moves
Use the two numeric fields, then Calculate score. This tool uses whole numbers. Return to the explanation when a decision is unclear. Work at your own pace.
An example to follow
A knock of 8 against 5 is an undercut: the defender receives 28. Gin against 18 earns the knocker 43. Use another round to revisit a decision.
An important reminder
Keep the active rule in mind. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. Check the relevant controls before continuing.
