Your objective
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. Before making a move, check the cards in view.
Work through the instructions
- 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.
The controls to know
Use the two numeric fields, then Calculate score. This tool uses whole numbers. Check the relevant controls before continuing. Work at your own pace.
An example to follow
A knock of 8 against 5 is an undercut: the defender receives 28. Gin against 18 earns the knocker 43. Return to the explanation when a decision is unclear.
Avoid this misunderstanding
Begin with the objective. 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.
