SpotCircleLock is an endless timing game built for quick one-finger aim. A still target sits on the field, and you tap to place an expanding circle, then tap again to lock its size. Covering the target scores ten points, while a miss counts as a fault. Three faults end the run at once. There are no stages to unlock, only a rising score chase. As points climb, targets shrink and lock windows tighten. When the session ends, compare your score with your high score, return to the main screen, and chase a longer clean locking streak.
Tap to place and lock a circle over the target. Misses count as faults.
