Your goal
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. Take a moment to read the table.
The order of play
- 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. The same rule applies on a phone and on a computer. A clear plan starts with the current position.
Try this example
A knock of 8 against 5 is an undercut: the defender receives 28. Gin against 18 earns the knocker 43. Check the relevant controls before continuing.
Check this before moving on
