Rules & objective
Match every pair with as few turns as possible.
- Turn over two different unmatched cards. Matching symbols stay face up.
- Mismatched cards turn back after a short delay. Wait for that turn to finish before selecting the next pair.
- Clear every pair to finish. A turn is counted when you reveal the second card, and fewer turns is the better recorded result.
Key terms
- Pair
- Two cards showing the same symbol.
- Turn
- One attempt made by revealing two cards.
- Known location
- A card position whose symbol you have already seen.
