Your guide to Gin Score Calculator
For a calm first round, focus on one decision. Calculate a Gin hand score from the knocker’s and defender’s final deadwood totals. Use another round to revisit a decision. A clear plan starts with the current position. Enter the knocker’s deadwood from 0 to 10. Zero means Gin. Take the next action only when the current step is clear.
