Whoever is in the lead when play stops if someone has completed 5.5 phases or more is the winner. Many people shorten the game by aligning it to baseball rules and consider 5.5 phases to be a complete game when running out of time to complete the full ten phases. The game is named after the ten phases (or melds) that a player must advance through in order to win. It consists of a special deck equivalent to two regular decks of cards, and can be played by two to six people.
