Pig Pile is an extremely light card (and punny) game. The cards have illustrations of pigs (naturally), and you can be "hog tied" or have a "hog wash".
Players start with three face-down cards (called "Slop") and a hand of six cards. At the start you place three of your cards face-up on top of the slop cards, leaving you with a hand of three cards. Each turn you must play to the central "Pig Pile" one or more cards of the same value that are equal to or greater than the top card of the Pig Pile. If you fail to do so, you must take the entire Pig Pile into your hand.
