LockTap puts a full-screen brass combination lock dial in your hands. The dial spins continuously like a real safe. Each level generates a three-number combination — for example rotate right to 23, then left to 08, then right to 31. An amber needle sits at the top showing the current number. Tap the screen when the needle lines up with your first target. The dial clicks, reverses direction, and you work toward the second number. Three clicks in the correct order and the vault opens. Miss the window and the combination resets — the dial keeps spinning and you try again from the first number. Accuracy is everything. Each tap is scored based on how precisely you hit the target. The closer to dead centre the higher your score. As levels progress the tolerance window shrinks, demanding finer and finer timing to match each number. The dial also spins faster with every level, giving you less time to react.
