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.
How to use the controls
Use the two numeric fields, then Calculate score. This tool uses whole numbers. Use another round to revisit a decision. Use the rule sheet as a reference.
A useful example
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
For a calm first round, focus on one decision. 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.
