Hard memory game on a six by six grid with several matched pairs in green frames

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 Memory Match

  1. Every card hides a symbol, and every symbol is on exactly two cards.
  2. Tap or click a card to turn it over, then turn a second card.
  3. If the two symbols match, the pair stays face up. If not, both cards turn back down after a moment.
  4. Each pair you turn counts as one move. Find every pair to finish.
  5. The timer starts when you turn the first card. Your best time is kept for each board size.

How to play the hard memory game

  1. Tap or click a card to turn it over, then turn a second card.
  2. A match stays face up with a green frame; a mismatch turns back down.
  3. Turn a third card to flip a mismatch back at once.
  4. Each pair turned is one move. The minimum is 18.
  5. 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.

Frequently asked questions

How many cards are in the hard memory game?

Thirty-six cards, 18 pairs, on a 6×6 grid. The symbols are chosen from a set of 24.

What is a good move count on 6×6?

With perfect memory the average is about 28 moves. Anything in the low 30s is a strong game.

How do I remember more cards?

Split the grid into top and bottom halves, name each symbol with its row and column, and clear known pairs straight away.

Is the hard memory game much harder than 4×4?

Yes. It has more than twice as many pairs, and cards seen early must be remembered through many more turns.

Can colour-blind players tell the cards apart?

Yes. Every symbol has its own shape, so colour is never the only difference between two cards.
