I have confirmed your correction with my crack in-house Dolmetcher staff (15 years old-don't ask me how he knows).
Thanks for the correction.
You are to be commended for having a son who knows all about medieval dice/board games! No wonder Bavarian schools are still ranked at or close to the top in Germany.
