Problem

Spot It costs about $\$ $10 at game stores. It consists of 55 cards with 8 pictures on each one. Each player gets one card. Deck goes in the middle. When you see a match between your card and the top card on the deck, you call it and collect that card, putting it on top of your old card. Your card will always have a match with the center card, so it's just a question of who can spot their match first. Fun game; no math content.

The math question is how they did it. How can you make all those cards, with every pair of cards having exactly one match?!

More information on using this in a math circle can be found at Math Mama Writes.
