Memory Game

How to play the memory game

1. Choose a board. 4x4 (8 pairs) is a quick warm-up; 6x6 (18 pairs) is the classic; 8x6 (24 pairs) is a proper workout.
2. Choose what is on the cards: pictures, numbers or letters. Numbers and letters are harder because the faces look alike.
3. Press Start and flip any two cards. If they match, they stay face up; if not, they turn back after a moment.
4. Remember where each picture was. When a new card shows a picture you have seen, go straight to its twin.
5. Clear the board. Your moves, time and accuracy appear at the top; the best result for each board size is kept in this browser.

What the results mean

Three numbers describe a round:

• Moves: every pair of flips counts as one move. The minimum is the number of pairs on the board (8 on 4x4, 18 on 6x6), which you can only hit with perfect luck or perfect memory.
• Accuracy: matches divided by moves. 50% means half your guesses were right; a strong player on a 6x6 board reaches 60-70%.
• Time: from the first flip to the last match. Time rewards decisiveness, so it tends to improve faster than moves.

The ratio that matters is moves divided by pairs. Under 1.5 is excellent, 1.5-2 is good, 2-3 is normal and over 3 means you were mostly guessing. The status line translates your result after every round.

Strategy: how to win with fewer moves

The game is really about spatial memory, remembering where things are, more than what they are. A few habits make a big difference. Start by flipping cards you have not seen; a fresh card always adds information, while re-flipping a known card without a match in mind wastes a move. When a card is turned back over, say its position in your head ("top right, strawberry"), because naming a location fixes it better than looking at it. Scan the board in a fixed order, row by row, so you never lose track of which cards are unexplored. And when the second card of a pair is already known, flip the unknown card first: if it happens to show a face you know, you can complete that pair instead and save a move.

The numbers and letters sets are harder because the faces are visually similar and easy to confuse, which is closer to the way real memory tasks work. The pictures set is better for children and for a quick break.

Does a memory game train your memory?

Playing improves your score on this game quickly, mostly because you learn the strategy above. Whether that transfers to remembering names or shopping lists is less clear: studies of brain-training games find strong gains on the trained task and small or no gains elsewhere. What a round does reliably do is give you a few minutes of focused attention, which is why memory games are used in classrooms, in recovery after concussion and in care homes. If you want numbers that are closer to the tests psychologists use, try the number memory test, the visual memory test and the chimp test.

Common problems and fixes

The cards do not flip

Press Start first to deal the board. During the short pause after a wrong guess, clicks are ignored so both cards can turn back; wait for them to flip and try again.

The board is too small on my phone

Turn the phone sideways for the 8x6 board, or pick 4x4 or 6x4, which keep the cards large enough to tap in portrait.

The pictures are not showing

The picture set uses standard emoji. On a very old system without colour emoji the cards may show empty boxes: switch to Numbers or Letters.
