Choose the profile first
The scorebook uses a fixed training profile: twenty for Gin, ten for an undercut, and a hundred-point target. It does not add box, game or shutout bonuses. If your table uses different rewards, use a different ledger rather than quietly changing the meaning of a recorded round.
Record one completed round
Select the knocker or Gin player. For a knock, enter their positive deadwood count and the defender’s final count after legal layoffs. For Gin, enter the defender’s own count without layoffs. A void deal adds no points.
Check and correct
Read the result and running totals before the next deal. A round award is kept in full even when it takes a player past the target. Undo removes the most recent round and reopens a completed match if necessary.
