A trick taking game using a custom 54-card deck with a "revolutionary" alphabetic design. Similar to "Wizard" and other trick-taking games you must guess the number of tricks you will take each round, but the total number guessed cannot equal the hand-size for the round (forcing at least one player to lose each round). Hand size starts at 8 then decreases by 1 each round until it is only 1 card, then it increases (1 card each round) back to 8. The deck includes rules for three games: UG I-is the standard 2–6 player trick-taking game UG II—is played in partnerships UG III—is a solitaire variant of the game From the rule book: In the future, the metric system will be adopted worldwide. The Universal Deck is the first to adopt a truly metric size, 6 x 9 cm. This makes the cards 1/8" narrower than a poker deck, 1/8" wider than a bridge deck, and 1/16" longer than both.
