Crypto Menko are collectible digital artworks inspired by Japanese Menko cards.

Menko (めんこ, 面子) is a Japanese card game played by two or more players. Each player uses Menko cards made from thick paper or cardboard, printed on one or both sides with images from anime, manga, and other works. A player's card is placed on the floor and the other player throws down his card, trying to flip the other player's card with a gust of wind or by striking his card against the other card. If he succeeds, he takes both cards. The player who takes all the cards, or the one with the most cards at the game's end, wins the game.
