Rotate your phone around the axis perpendicular to the screen (like a steering wheel) so gyroscope Z-axis spin turns the vault dial; align the pointer with the green target inside a shrinking tolerance and hold steady to clear each level—input below the dead zone is ignored and fast spins overshoot so you must micro-adjust in reverse, three stable misses end the run, and your score combines cleared levels plus precision bonus.
This is a casual game.
