GapLockSlide is a precision alignment challenge. A horizontal line with a gap sits across the screen, and you drag a vertical line left or right until it sits cleanly inside that gap. Hold a good align briefly to score. Large deviation or running out of time counts as a mistake, and three mistakes end the run. Higher scores shrink the gap width and shorten the round timer, so coarse swipes stop working. Move smoothly, fine-tune near the opening, and lock in before the clock expires. The game favors steady control as alignment tolerance keeps tightening.
