Shuffle the cards and deal four cards to each person. Tell players to look only at their own cards. Explain that when the game starts, players each have to trade their cards quickly with someone else who wants to trade the same number of cards. They’ll know what cards they’re giving away, but they won’t know what cards they’re receiving until they’ve traded them. The object is for a player to continue 'blind' trades until he or she has four matching cards. First player to get four matching cards should get a treat like a piece of chocolate. Play as many rounds as you want—and be sure everyone gets a treat in the end!

Tip: If you have more than 13 people in your group, you’ll need to add in a second deck of cards. If you have more than 23 people, you’ll need three decks of cards, and so on.

To make the game a little more challenging, play the game with more decks, and have players match eight of a kind for double the fun!
