Flip cards to find matching pairs, built with pure React (no game engine).
How to play
All cards start face down. Click a card to flip it, then click a second card.
If the two cards match, they stay face up. If not, they flip back after a moment.
Match every pair to win, in as few moves and as little time as you can.
One move is one pair of cards flipped. The timer starts on your first flip.
Watch the color sequence, then repeat it — built with pure React (no game engine).
How to play
Press Start. Simon lights up a pad and plays its tone.
Repeat the sequence by pressing the pads in the same order.
Each round, Simon adds one more step to the sequence.
Your score is the length of the longest sequence you repeated correctly.
