Knucklebones, Tali, Fivestones, or Jacks, is a game of ancient origin, usually played with five small objects, or ten in the case of jacks. Originally the "knucklebones" were those of a sheep, which were thrown up and caught in various manners. Modern knucklebones consist of six points, or knobs, proceeding from a common base, and are usually made of metal or plastic. The winner is the first player to successfully complete a prescribed series of throws, which, though similar, differ widely in detail. The simplest throw consists in either tossing up one stone, the jack, or bouncing a ball, and picking up one or more stones or knucklebones from the table while it is in the air. This continues until all five stones or knucklebones have been picked up. Another throw consists in tossing up first one stone, then two, then three and so on, and catching them on the back of the hand. Different throws have received distinctive names, such as "riding the elephant", "peas in the pod", "horses in the stable", and "frogs in the well".
