PairLock is the memory match game with a twist you've never seen before. Flip cards, find matching pairs, and connect them with a line. But here's the catch: your lines can never cross. It's the memory game you know, with a puzzle layer you don't. HOW TO PLAY Tap cards to flip them. Find two matching symbols and they stay face up, connected by a colored line. But every line you draw creates a web. Match too quickly without thinking and you'll box yourself in. Plan your pairs carefully to avoid crossed lines and earn a perfect score.
