Trio

On your turn, choose any single card to reveal, either the low or high card from a player's hand (including your own) or any face-down card from the table. Then, do this again. If the two cards show the same number, continue your turn; if they do not, return the cards to where they came from and end your turn.

If you reveal three cards showing the same number, take these cards as a set in front of you. 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 or subtract to 7, e.g., 4s and 11s.
