Abstract: This invention relates to card games in which cards are traded and in which scores that depend on the combination of cards held by a player are tallied by means of score cards and markers. The score cards have charts with values and cross-reference multipliers by which the value of each of a player's card's is determined by references to other related cards that he may possess. The cards are traded by a system of offers and acceptances, credits and debts. The current state of a player's hand of cards is tracked by markers located on squares of each player's score card corresponding to the particular cards held. The value of the combination of his current cards, and of possible combinations that he may be able to acquire by trading, are calculated by the player consulting his score card.
