Trio is a card game in which players search for three of a kind. The deck consists of 36 cards numbered 1-12 three times. Players are given a number of cards in their hand, which they must sort from low to high, and the remaining cards are placed face down on the table. When it is your turn, you choose a random card to reveal, either the low or high card from a player's hand (including your own) or an open card from the table. Then do this again. If the two cards show the same number, you continue your turn; if not, you return the cards to where they came from and end your turn. If you reveal three cards with the same number, you take these cards as a set. If you are the first player to collect three sets, you win—except that a player wins immediately if they collect the set of 7s or two sets that add up to or subtract 7, for example, 4s and 11s.
