Flip two cards at a time and find every pair. Race the clock solo, outsmart a computer that genuinely remembers what it sees, or challenge a friend.
The computer opponent never cheats: it doesn't know where the cards are. It builds its own memory one glimpse at a time, every card revealed by you or by it has a chance of being remembered, depending on the difficulty. “Forgetful” loses track of most cards, “Sharp” keeps about three-quarters, and “Elephant” almost never forgets, which makes it a genuinely tough opponent.
Each pair is worth 100 points, matches in a row earn a growing combo bonus, every miss costs a few points, and a fast finish adds a time bonus. Stars depend on how few moves you needed compared with the number of pairs.
Hint makes the matching card of the one you've just flipped glow for a moment (or, with nothing flipped, points you to a card you haven't looked at yet). Peek turns every card face-up for a second and a half. Both are limited per game and noted in your results, so a no-help win is still something to be proud of.
Yes, use the arrow keys to move between cards and Enter or Space to flip. H gives a hint, K peeks, P pauses and N deals a new game.
Yes, per board size, in this browser only, nothing is uploaded and it won't follow you to another device.
