How to play
- Turn over a card by tapping or clicking it, or with Tab and Enter on a keyboard.
- Turn over a second card. If the pictures match, both stay face up.
- If they don't match, both turn back over after a moment. Try to remember where they were.
- Find every pair in as few moves as you can.
How your score is worked out
The best possible game finds each pair with one move, which only happens with lucky guesses. Your score compares that with the moves you took:
Score = pairs ÷ moves × 100 (rounded, out of 100)
| Game | Working | Score |
|---|---|---|
| 8 pairs in 16 moves | 8 ÷ 16 × 100 | 50 |
| 12 pairs in 20 moves | 12 ÷ 20 × 100 | 60 |
| 8 pairs in 8 moves | 8 ÷ 8 × 100 | 100 |
Tips to remember more cards
- Work row by row. Turning cards in order makes their places easier to remember than jumping around.
- Say it in your head: "clock, top left; moon, second row". Words can help you remember.
- Use your first card wisely. Start each move with a card you haven't seen yet. If it matches one you remember, go straight to that one.
Frequently asked questions
Can I play with a keyboard or screen reader?
Yes. Each card is a button. Use Tab to move between cards and Enter or Space to turn one over. Screen readers hear the card's picture name when it is face up.
Is my score saved?
Only while the page is open. We don't use cookies or browser storage, so it is forgotten when you close or reload the page.
Is the deck shuffled fairly?
Yes. The cards are shuffled with the Fisher-Yates method, which gives every order of cards the same chance.
