The classic concentration card game in your browser — the deck is already shuffled when the page opens, and how fast the cards flip back is yours to set
Use the arrow keys to move across the board, Enter or Space to turn a card, Esc to deselect.
The rules of the concentration card game: a deck of matched picture pairs is laid out face down in a grid. Each turn you reveal exactly two cards. Same picture, and they stay face up as a completed pair. Different pictures, and they flip back after a short pause. Clear every pair and the board is done; in relaxed mode there is no losing condition at all. Tapping the card you have already selected simply deselects it, and costs you neither a move nor a miss.
How moves and misses differ: a move is a completed turn — it ticks up the moment you reveal the second card, match or not. A miss is narrower and only lands in one situation: the second card of the turn is one you had already seen this round, and it still did not match. Leading with a card you know in order to fish for a new one is sound play and is never penalised, and a successful match never counts as a miss. Since more cards inevitably means more moves, misses are the number that stays comparable across board sizes.
Which board size to pick: 6 pairs suits younger players and a genuinely quick break; 8 pairs is the default and lands around 60 seconds; 10 pairs rewards players who sweep the board systematically before committing. The board deliberately stops at 10 pairs — going bigger only stretches a round into several minutes, which defeats the point of a game you open while waiting for a bus. Extra difficulty comes from the move and time limits instead.
Setting the flip-back delay: three options, 0.4s, 0.8s and 1.4s, with 0.8s as the default. The choice is written to this device and still applies the next time you open the page, so you set it once rather than every round. Slowing it to 1.4s while you are learning, or while playing alongside a child, is an entirely legitimate move; dropping to 0.4s noticeably shortens a round once you are fluent. The delay changes only how long a mismatched pair stays visible — moves, misses and scoring work identically at every speed.
House rules for two players: the built-in hot-seat mode is "match and continue, miss and hand over", settled on pairs first and misses second. Two variants worth trying: "open study", where both players look at the face-down layout for five seconds of free reveal before starting, and "relay", where the phone passes on every miss and you count who cleared the most pairs. Two-player rounds are deliberately kept out of the personal best table and out of the daily board.
