Watch the pattern. Repeat it. Go one round further than yesterday. That's the whole game. And you'll be thinking about it at midnight. Five game modes. Each one hits differently. Classic builds your foundation. Speed turns up the pressure. Reverse flips the sequence. Mirror forces your brain to translate before it responds. Tilt replaces tapping entirely โ€” you physically tilt your phone to answer. The grid grows as you do. Start on a 2ร—2. Hit round 10 and a 3ร—3 unlocks. Hit round 20 and a 4ร—4 unlocks permanently. Every future game starts at the largest grid you've ever earned. Real metrics. Not made up. Focus Score tracks how consistent your reaction time is across rounds. Memory Span measures the longest sequence you recalled this session. Your Stats screen shows exactly where you stand โ€” your level, your next goal, your strongest mode, and a 28-day practice calendar. We believe focus shouldn't be a subscription. Free to play. No account. No login. Ever. PatternMaster is designed for entertainment purposes only and does not claim to diagnose, treat, or improve any medical condition or cognitive function.
