Thank you for viewing! This is the puzzle "Nomi Nazo" by Tri-Mebius. It's new and unused, but I may have opened it once, though my memory is hazy. The contents haven't been touched. The way to play is a bit unusual. You solve the puzzle alone first, and then you present it to multiple people. Please refer to the second photo for details. I think it can also be used for social gatherings, etc. For those who don't mind that it has been handled by someone else. Thank you very much! #puzzle #TriMebius #thinking #RealEscapeGame #boardgame #tablegame #mixer #drinkingparty #takeoutpuzzle #socialgathering
