Reversi Dedicated to Schrödinger: Othello I opened it, but it's unused. Please note that it will be shipped with only water damage protection (no cushioning). #Shiikaiseki Board Game Card Game A new sensation of Reversi, adding neutral gray to the well-known Othello. Uses three types of pieces: white pieces, black pieces, and neutral gray pieces. Since all the pieces are the same on the back, you can enjoy the thrill of flipping them over. You can place any piece you like, not only your own color, but also your opponent's color and neutral quantum pieces.
