Goal: find every matching pair — two cards showing the same number.
How: tap two face-down cards. If they match, they stay flipped. If not, both turn face-down again.
Moves: each pair of flips counts as one move. Try for the fewest moves you can!
Timer: clear the board before time hits zero.
Levels: there are 20 stages — each gives you less time and fewer hints. When you clear the board, the next stage starts automatically after a short moment. Restart replays the stage you’re on.
