How it works

The classic memory game. Cards lie face down in pairs: turn two at a time, remember what you saw and find every pair in as few moves as you can. Play solo for the leaderboard or race friends on the same table.

  • Each move turns two cards. The same picture twice stays up; two different ones turn back.
  • Each pair is worth 100 points; each move past the fewest costs 10, each second 1.
  • Normal is 8 pairs, Hard is 18, each with its own leaderboard.

What is MemoryBoo?

MemoryBoo is the classic memory game, also known as concentration or matching pairs. A table of cards lies face down, and every picture on it appears on exactly two cards. Each move, you turn two cards. If they show the same picture, the pair stays face up. If they don’t, both turn back after a moment, and it’s up to you to remember where each one was.

A game is short. The 4 × 4 table of 8 pairs often takes a minute or two, the 6 × 6 table of 18 pairs a few minutes more. The pictures are simple silhouettes – a bee, a bus, a giraffe, a guitar – each in its own colour, so they are easy to tell apart and still a real test to keep in your head.

A card matching game, now with a score

Card matching has been played with an ordinary pack of cards for generations: spread them face down, turn two, keep the pairs. MemoryBoo keeps that simple rule and adds points, so every game can be compared with the last one and with other players.

It is free and runs in your browser, with no sign-up and nothing to install. Solo games go on a leaderboard you can view for today, this week, this month or all time. Duo and Group rooms let you race friends on the very same table, joined with a short code or a link. The site comes in eleven languages, in light and dark.

Who it suits and what it trains

MemoryBoo suits anyone who likes a quick, calm puzzle: children practising concentration, grown-ups warming up over a coffee, families playing side by side. It trains short-term visual memory – holding several places and pictures in mind at once – and it rewards care over haste, because a wasted move costs ten times more than a second of thinking.

Good to know

Normal and Hard each keep their own leaderboard, so a quick 8-pair game never competes with an 18-pair one. If you reload the page in the middle of a Solo game, the table comes back as you left it.

ColorBoo

One tile is a shade off

Every tile is the same colour but one. Tap the odd one out to climb a level: the grid grows and the colours draw closer, until your eyes can’t tell them apart.

HueBoo

See it, then dial it back

A colour shows for a few seconds, then hides. Rebuild it from memory with three dials — hue, saturation, brightness — and see how close you got. Five colours a game, ten points each.

MineBoo

Clear the meadow, dodge the mines

Our own take on Minesweeper. A meadow hides mines: open every cell without one, with numbers telling how many mines lie around each. Every game starts with a patch already open, so nobody has to guess blind. Play solo for the leaderboard or race friends on the same field.

FruBoo

Merge fruits, make a watermelon

The fruit merge game. Drop fruits into the box: two of a kind that touch become the next fruit up, from cherry to watermelon. Keep the pile under the line as long as you can. Play solo for the leaderboard or race friends with the same fruits.

How to play MemoryBoo

Find every pair of pictures on the table in as few moves, and as little time, as you can. A game of this memory game takes one to four minutes. All you need is a mouse, a keyboard or a finger on a touch screen.

The goal: find all the matching pairs

Every picture on the table appears on exactly two cards. Turn them up two at a time and find all the pairs: 8 on Normal, 18 on Hard. The table is cleared when the last pair is face up. Fewer moves and a quicker finish mean more points.

How a game of MemoryBoo goes

  1. On the start screen, choose Solo, Duo or Group and pick the table: Normal (4 × 4, 8 pairs) or Hard (6 × 6, 18 pairs). Then press Play.
  2. All the cards lie face down, their backs showing the mascot’s eyes. The clock starts when you turn your first card.
  3. Turn one card, then a second. Two cards turned make one move.
  4. If both show the same picture, it’s a pair: the two cards stay face up for the rest of the game.
  5. If they differ, they stay up for just under a second and then turn back. Turn your next card and they go back at once, so you never have to wait.
  6. Keep going, using what you have seen, until every pair is face up. Your result opens with the moves, the time and the points.

Scoring and leaderboards

Each pair you find is worth 100 points. The fewest moves possible is one per pair, and every move past that costs 10 points. Every whole second on the clock costs 1 point. The score never drops below 0.

An example: you clear the Normal table in 14 moves and 50 seconds. That is 8 × 100 = 800, minus 6 extra moves × 10 = 60, minus 50 for the time: 690 points.

A Solo score goes on the leaderboard as soon as the table is cleared, under the player name in the header. Normal and Hard each have their own leaderboard. Each keeps one entry per player – their best – and can be viewed for Today, Week, Month or All time.

How a game ends

A Solo game ends when the last pair is turned up. There is no time limit and no way to lose, only a better or a worse score. To start over in the middle, press Restart, then press it again within three seconds when it asks “Sure? Tap again”.

In a room, the round ends when everyone has cleared their table, or after ten minutes. Most points wins; on a tie, whoever finished sooner is ahead.

Controls

  • Mouse: click a card to turn it.
  • Touch: tap a card.
  • Keyboard: Tab to the table, move between the cards with the arrow keys and press Enter or Space to turn the one in focus.
  • Esc closes the result card; See result opens it again.

Solo, Duo and Group

Solo is you and the table, with your best score on the leaderboard.

Duo is two players and Group is up to eight. Choose the mode and the table on the start screen, then press Play: this opens a room with a five-character code. Share the code, or press Copy link and send the link. When everyone is in, the host presses Start round.

Everyone gets the same table and clears their own copy, and each player’s clock starts with their own first card. The players list shows everyone’s pairs and moves as they go, and their points once they are done. When the round is over, the standings show each player’s moves, time and points, and the host deals the next table. Room rounds don’t go on the leaderboard.

Tips for a better score

  • Start each move with a card you have never seen. If it matches one you remember, turn that one second.
  • If the first card is new and you don’t know its partner, turn another unseen card second. Turning a card you already know won’t match wastes a move and teaches you nothing.
  • Name the pictures with their places in your head, such as “bee, top left”. Words often stick better than shapes.
  • Work through one part of the table at a time, row by row, instead of jumping around.
  • Don’t rush. A wasted move costs 10 points, as much as ten seconds of thinking.
  • Use found pairs as landmarks, especially on Hard: they help you place the cards around them.
