25 cards are laid face-down. Flip two at a time — if the colors match, they disappear.

Each card shows how many times it has been flipped on its face-down side. Use this to track which cards you've already seen.

12 color pairs are hidden in the deck. One lone card has no pair. It's the outcast.

Clear all pairs as fast as you can. The outcast color is revealed at the end.
