As each trick is completed, the cards played in that trick are collected, face down, in front of the player who won that trick. They do not return to play during that hand. If the number is less than the bid, the players each lose a number of points equal to the bid. If the number is equal to or greater than the bid, the players each earn a number of points equal to the bid. There is no penalty for exceeding your bid.
Every player plays for themselves, and has their own individual score.
Play continues until all parties decide to stop. If you have more than six people wanting to play, but less than the ten needed to make two separate games, you may wish to consider using two decks. The player who has won the bid gets to choose a magic card as before. But, since there are two cards with the every suit and number, the winner of the bid can have two, one, or no partners, depending on where the two Magic Cards happen to be. All partners, regardless of how many they are, are responsible for making the bid, as before.
