Gin Score Calculator: what to know before playing
Work at your own pace. 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. For a calm first round, focus on one decision. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. Take the next action only when the current step is clear.
Fixed house bonuses of 25. It does not include line bonuses or a match-end bonus.
An idea for your next attempt
Take a moment to read the table. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed. Return to the explanation when a decision is unclear.
The challenge in front of you
Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Check the relevant controls before continuing. Begin with the objective.
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.
Controls
Use the two numeric fields, then Calculate score. This tool uses whole numbers. Take the next action only when the current step is clear. Treat this as a chance to practise one rule.
Try this example
A knock of 8 against 5 is an undercut: the defender receives 28. Gin against 18 earns the knocker 43. Use another round to revisit a decision.
Watch out for this
Keep the active rule in mind. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. Check the relevant controls before continuing.
