Take a closer look while playing

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.

Your goal

Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. Look at the complete hand before deciding.

The order of play

  1. Enter the knocker’s deadwood from 0 to 10. Zero means Gin.
  2. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed.
  3. Calculate the result. Gin scores 25 plus defender deadwood; an undercut scores 25 plus the difference.
  4. 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. Return to the explanation when a decision is unclear. Work at your own pace.

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.

An important reminder

Treat this as a chance to practise one rule. Enter post-layoff values. This arithmetic tool does not choose card groupings from card images. Use another round to revisit a decision.
