A walkthrough of the rules
- 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.

A closer look at one example
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.
