Test and improve your memory with a quick game of card matching! The game begins with a 6x6 grid of face-down cards, hiding 9 different card faces. Flip a pair of cards with each turn and try to remember what's been revealed. A matching pair will be removed from the board, while a non-matching pair will be flipped back again for future turns. Match all 18 pairs with the fewest number of turns to improve your accuracy score!
