Pairs Race

Everyone gets the same face-down cards, shuffled differently: find all the pairs as fast as you can.

Rules

1. Every player gets the same face-down cards, shuffled in a different order.
2. Turn over two cards: if they match, the pair stays face up; if not, they turn back over when you pick the next card.
3. Finding all the pairs quickly scores the most points.
4. Easy: 12 cards. Normal: 16 cards. Hard: 20 cards.
