Getting started with Gin Score Calculator

Begin with the objective. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Check the relevant controls before continuing. Treat this as a chance to practise one rule. 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.

Bring this focus to a round

Treat this as a chance to practise one rule. Enter the defender’s deadwood after any legal layoffs; against Gin no layoff is allowed. Take the next action only when the current step is clear.

What counts as success

Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Return to the explanation when a decision is unclear. For a calm first round, focus on one decision.

Start here and follow along

  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.

How to interact with the game

Use the two numeric fields, then Calculate score. This tool uses whole numbers. Check the relevant controls before continuing. For a calm first round, focus on one decision.

One way to understand the rules

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.

An important reminder

Use the rule sheet as a reference. 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.
