Trio Card Game Rules

Trio is a deduction and memory card game published by Cocktail Games, designed by Kaya Miyano and illustrated by Laura Michaud. It plays with 3 to 6 players, from age 7 up, and fits in a tiny box: 36 cards and a rulebook. The whole idea holds in one sentence — work out where the three copies of the same number are hiding, in your opponents' hands or on the table.

Objective

Your goal is to win trios, meaning the three cards that share the same number. The 36 cards are made of twelve numbers, from 1 to 12, each present in three copies. The trio of 7 has a special status: claiming it wins the game outright, whereas otherwise you need to collect three trios.

Setup

Shuffle the cards and deal them evenly between the players, following the count given in the rulebook for your player number. The remaining cards are placed face down in the middle of the table. Each player sorts their hand in ascending order without showing it. That ordering matters enormously, because only the cards at either end of a hand can ever be revealed.

How to Play

On your turn, you reveal two number cards, one at a time. Each revealed card is taken either:

• from the table, among the face-down cards; or
• from a player's hand — including your own — but only their smallest or their largest number.

A card in the middle of a hand is never revealed, under any circumstances. You have to wait until it becomes the smallest or the largest card of that hand. If the two revealed cards are identical, you play on and reveal a third; if all three match, you win the trio and place it in front of you. You do not take another turn for it — play passes to the next player.

If the two revealed cards are different, your turn ends immediately, even if you know exactly where the matching third card is. The revealed cards are turned back over, and this is where memory takes over: everyone at the table saw that information go by.

You may ask one player for their smallest card and then another player for their largest, or even ask the same player twice, as long as the requests happen one after the other. A player holding two copies of the same number only reveals one at a time: you have to ask again for their largest (or smallest) card to see the second copy.

Scoring and End of Game

There is no point scoring in Trio — you simply count trios won. The game ends as soon as a player has won three trios, or as soon as someone claims the trio of 7. Running out of cards in hand does not eliminate anyone: you keep playing normally, just with less information than the others, since a trio can be won using only cards from the table and from opponents' hands.

Common Variants

The rulebook offers two game modes, SIMPLE and PICANTE, plus a team rule. In team play, partners may exchange cards, but those exchanges are optional: a player with no cards left in hand simply plays without them.

Why This Game Is So Popular

Trio is understood in a minute and demands an immediate rematch. Its strength lies in the double edge of every reveal: the information helps you, but it helps your opponents too, and they can steal the trio you have been setting up for two turns. The most memorable moment is almost always the same — a player flips two identical cards, the table holds its breath during the third reveal, and everything hinges on one card.

Beginner Mistakes to Avoid

• Trying to reveal a card from the middle of a hand — forbidden, including in your own hand.
• Assuming a trio held in hand is already won: it can only be played if all three cards are accessible, one after the other, at the ends of hands.
• Sitting on a trio too long hoping for a better moment: an attentive opponent can take it from you.
• Failing to memorise the cards other players reveal, when that is exactly where the game is won.

FAQ

1. Can I reveal a card from the middle of a hand? No, never. A card can only be revealed if it is on the table or at the end of a hand, meaning the smallest or the largest.

2. I have a full trio in hand — can I play it? Only if all three cards are accessible in turn. If the copies are neither your smallest nor your largest cards, you have to wait.

3. Is the trio of 7 easier to claim? No, it follows exactly the same constraints as the others: all three "7" cards must be accessible, on the table or at the ends of hands.

4. I just won a trio — do I play again straight away? No, the turn passes to the next player.

5. Can I reveal two cards from the middle of the table? Yes, and even a third one if the first two revealed are identical.

6. Can I win a trio without using any card from my hand? Yes. If you find the three matching cards among your opponents' hands or on the table, the trio is yours.

7. In the team variant, can I exchange cards with my partner if I have no cards left? No, you play without the exchanges, which are optional in any case.
