About Memory Match

Memory Match, also known as Concentration or Pairs, is the card game where everything is face down. Turn over two cards: if they match, they stay up; if not, they turn back, and you try to remember what was where.

It is quick to learn, takes a minute or two a round, and is genuinely good practice for short-term memory. Every card shows a distinct shape as well as a colour, so the game works for everyone, on a phone or a computer.

How to play Memory Match

Choose a size: Easy 4 × 3 (6 pairs), Medium 4 × 4 (8 pairs), Hard 6 × 4 (12 pairs) or Expert 6 × 6 (18 pairs).
Click or tap a card to turn it over, then turn over a second one.
If the two cards show the same shape, they stay face up as a pair.
If they are different, they turn back over after a moment, or straight away when you turn the next card.
Find every pair to finish. Try to beat your best time and your fewest turns.

Memory Match rules

Turns

A turn is two cards. A matching pair stays face up; two different cards stay up for about 0.9 seconds so you can see them, then turn back. Turning over a third card turns them back straight away.

Finishing

The game ends when every pair is face up. Your time and the number of turns you took are shown, and the best of each is saved for every size.

The perfect score

A game cannot be finished in fewer turns than there are pairs, and only luck gets you close to that. With a good memory, a game usually takes somewhere between one and a half and two times as many turns as there are pairs.

Time, pause and saving

The clock starts when you turn the first card and stops while the game is paused, when the cards are hidden. Your game in progress is saved in this browser, so you can leave and come back to it.

Tips and strategy

Work through the board in order, left to right, so you always know which cards you have not seen yet.
If the first card of a turn matches one you have already seen, turn that one over next. If not, use your second card to look at one you have not seen yet.
Say the shapes to yourself as you see them: “star, top left”. Words stick better than pictures alone.
Group what you remember by rows: it is easier to recall “the moon in row two” than an exact square.
