Work at your own pace. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Return to the explanation when a decision is unclear. Begin with the objective. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. Take the next action only when the current step is clear.

Practice with a purpose
A clear plan starts with the current position. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed. The same rule applies on a phone and on a computer.

How a round unfolds
- 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.
