Black Monkey Janken Strip — Pc Game Download Link

Another angle: "Black Monkey" could refer to the game "Donkey Kong," but that's a stretch. The "Janken" part does relate to rock-paper-scissors, which is a known mechanic in some games. "Strip" might allude to "strip poker," so maybe this is a parody or fan-made game combining those elements. However, such games are often not professionally developed and might not be available legally.
