Loteria. I only heard of it because we had to come up with four cards each. It's a card-game that's played in Mexico, apparently. I don't know how they play it, I only know that the deck contains 54 cards, each different, and numbered one to fifty-four. The images range from the abstract, like El Diablito (the Devil) and La Muerte (Death) to solid, clunky ones, like El Cazo (the Saucepan) and La Bota (the Boot).
