How does the memory match game work?
16 cards lie face down in a 4 × 4 grid: 8 pairs of pictures drawn for this site. Tap a card to turn it, then a second. If the two pictures match, they stay face up; if not, both turn back after a moment. Find every pair to finish. The clock starts on your first card, so you can take a breath before you begin.
How is your result calculated?
Your result is the number of moves, where one move is two cards turned. The fewest possible is 8, one per pair, which only happens if every first card you turn happens to be followed by its partner. In practice the first few moves are always exploration, so what matters is how few cards you turn more than once.
How do you get better at memory match?
- Never waste the second card. If you have already seen the partner of your first card, go straight to it. If not, turn a card you haven't seen: it tells you something new.
- Sweep in order. Turning unknown cards row by row makes their places easier to remember than jumping around.
- Name what you see. "Moon, top left" said silently sticks better than a picture alone.
What does it test?
Short-term memory for where things are, the same skill as in the Object Location Memory Test, plus a little planning. The game is old: card players know it as Concentration or Pairs.
