Your objective
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Take the next action only when the current step is clear. Take a moment to read the table.
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.
Using the playing area

One way to understand the rules
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.
One detail worth checking
Take a moment to read the table. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. Take the next action only when the current step is clear.
