Hard memory game: 18 pairs on a 6×6 grid
The hard memory game spreads 36 cards, 18 pairs chosen from 24 hand-drawn symbols, across a 6×6 grid. Cards you saw early have to survive a long run of new ones, so this is a proper test of recall. Free to play with no app, no sign-up and no interstitial before play; it works offline and plays fully from the keyboard.
How to play the hard memory game
- Tap or click a card to turn it over, then turn a second card.
- A match stays face up with a green frame; a mismatch turns back down.
- Turn a third card to flip a mismatch back at once.
- Each pair turned is one move. The minimum is 18.
- Clear all 18 pairs to win. Your time and moves show on the end panel.
Strategy for the 6×6 board
With 36 cards, the number of symbols you have seen but not matched can climb past ten in the middle of the game. A player with perfect recall averages about 28 moves here; most good players land in the 30s and 40s. The techniques below keep that middle stretch under control.
Split the grid into halves
Treat the top three rows and the bottom three rows as two separate 3×6 boards. Explore the top half first and clear its pairs before moving on. You carry fewer unmatched cards at once, and the second half is easier because many symbols are gone.
Store positions as coordinates
On six columns, "left, middle, right" is too vague. Use numbers: "bolt, row 2, column 5". It feels slow at first, but it stops the most common 6×6 error, remembering the symbol and turning the card next to it.
Retire pairs quickly
Whenever a new card matches one you know, take the pair on that move or the next. Every pair you clear is one less item to hold, and the colours help: two cards of the same shape and colour are easier to recall together.
Use the green frames
Matched cards stay face up with a green frame. Glance at them to see which symbols are finished, so you never waste a move on a shape that is already cleared.
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 6×6 board keeps its own best time.
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 6×6 grid fits a phone screen at about 46 px per card, and on a keyboard the arrow keys, Home and End move between cards without a mouse. 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.
