The challenge in front of you
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Check the relevant controls before continuing. A clear plan starts with the current position.
From the start of a round
- 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.
Getting comfortable with the controls
Use the two numeric fields, then Calculate score. This tool uses whole numbers. The same rule applies on a phone and on a computer. Work at your own pace.
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. The same rule applies on a phone and on a computer.
A common point of confusion
Work at your own pace. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. Check the relevant controls before continuing.
