How to play the memory game
- All cards start face down. Tap or click a card to turn it over.
- Turn a second card. If the two symbols match, both stay face up with a green frame.
- If they do not match, both turn back down after a moment. Turning a third card flips them straight away, so you never have to wait.
- Each pair you turn counts as one move, whether it matches or not.
- Find every pair to win. The fewest possible moves equals the number of pairs: 8 on 4×4, 18 on 6×6.
- On a keyboard, press Tab to reach the grid, move with the arrow keys and turn a card with Enter or Space.
Memory game strategy: fewer moves, faster clears
Luck decides the first few turns, but after that the difference between a good and a poor game is almost entirely how you store what you have seen. With a perfect memory, the average game takes about 12 moves on 4×4 and about 28 on 6×6. Most people start well above that; these habits close the gap.
Turn the unknown card first
Start each move with a card you have never seen. If it matches one you remember, turn that one second for a sure pair. If it does not, your second card should also be a new one, so every move teaches you two cards instead of one.
Explore in order
Work through unseen cards in reading order, row by row, rather than tapping at random. Your memory then only has to hold a few positions per row, and you always know which cards are still unknown.
Name the symbol and the place
Say it to yourself: "star, top row, third". Words stick better than images, and linking a symbol to its row and column makes the second card easy to find. Every symbol is a distinct shape as well as a colour, so the shape name alone is enough.
Clear what you know before guessing
When you turn a new card and remember its partner, take the pair at once. When your second card turns out to match an earlier one, claim that pair on the very next move before it slips your mind.
Keep a steady pace
Rushing costs moves, and moves cost time. A steady rhythm, with a short look at each pair before it turns back, usually beats frantic tapping on the clock as well as on the move count.
The cards and the two board sizes
The symbols are drawn for this site as flat shapes: circle, triangle, star, moon, heart, leaf, key, bell, anchor, cloud and more, 24 in all, each in one of eight colours. A game picks 8 of them for the 4×4 board or 18 for 6×6, places each on exactly two cards and shuffles the layout.
The 4×4 board is a quick game for a coffee break or for children learning the idea. The 6×6 board has more than twice as many pairs and turns into a real test of recall, because the cards you saw early have to survive a long stretch of new ones.
A card game with many names
Matching pairs is an old parlour game. Played with a deck of cards laid face down, it goes by Concentration, Pairs, Match Up and, in Britain, Pelmanism, and players take turns trying to find two of the same rank. There is no known inventor; the rules need nothing but cards and a table.
Picture versions for children followed, with pairs of illustrated tiles in place of playing cards. This version keeps the solitaire form of the game, where you play against your own move count and the clock.
Daily, stats and printables
The timer starts when you turn the first card, stops on the last pair and pauses when you switch tabs. Stats are kept per board size in your browser: games played, won, win rate, best time and average time. The Easy and Hard boards keep separate records.
There is no undo and no hint in Memory Match; the game is your memory against the grid. Each layout has a five-character puzzle code such as A7K3Q, so ?p= replays the same cards in the same places, which makes a fair race with a friend. Share result copies your time and move count. There is no daily Memory Match and no printable version.
Plays anywhere, no app, no account
The memory game grid fills the width of a phone with cards large enough to tap, and a keyboard player can reach and turn every card with the arrow keys and Enter. Tidy Puzzles runs entirely in your browser: there is no app to install, no account to create and no interstitial before you can play. After the first visit the game also works offline, because each puzzle is generated on your device from a seed. Every board can be played with the keyboard alone, on a phone or a desktop, and your stats and unfinished puzzles stay in this browser rather than on a server.
