Three spinning dials, one target code. Tap each dial to lock the right digit.
At the top of the screen you see a target combination — three digits from 0 to 9. Below it, three wheels spin independently. Each wheel cycles through 0 to 9 over and over at its own speed.
Tap a wheel to lock it at whatever digit is showing in its window at that instant. Once locked, that wheel stops spinning and stays at that number; the other wheels keep spinning while you wait to time them.
Lock all three wheels. The combination is then checked: if every locked digit matches the target, you crack the lock and score a point. If even one digit is wrong, you lose one of your three lives.
After each successful crack a new target appears and the wheels spin faster. The longer you survive, the tighter the timing windows.
Goal: crack as many combinations as you can before you lose all three lives.
Read the wheels' phase, not their position. Each wheel cycles 0 through 9 at constant speed, so once you know how long a full revolution takes, you can predict where any digit will land in time. Watch a full revolution of one wheel before locking anything — that's your calibration.
Lock the slow wheel last, the fast wheel first. Counter-intuitive but right: the fast wheel has the smallest timing window per digit, so you want a fresh attempt at it while your eyes are still on the target combo and reflexes are warm. The slow wheel has wide windows and lets you compose between locks.
Don't chase the digit if you miss it. Wait a full revolution rather than tapping the next number hoping it's close. The cycle returns and your lives are limited; panic taps are how runs end. A blown rotation costs you seconds, but a panic-locked wrong digit costs you a life.
