Trio actually comes with two sets of rules. It uses a custom set of player cards labeled with RUN, SET, RUN/SET, AP, TRIO and valued from 1 through 9. The object is to score 30 points by discarding runs, sets, pairs and other combinations to the discard pile. The second game plays 2-6 players, who try to be the first to collect the right cards to match any three of the four control cards dealt to each player at the beginning of the game.
