Fill One Line
Fill One Line is a puzzle game built around a deceptively straightforward idea — draw a single continuous path that covers every cell on the grid. No cell left empty, no backtracking allowed.
Obstacles scattered across the board force you to plan ahead rather than trace whatever feels natural. Some configurations have an obvious solution that quietly falls apart two moves in. Others look impossible until a less intuitive route suddenly clicks.
The grid shapes change as you move through levels, and so does the placement of barriers. What worked before won't carry you far here. The satisfaction comes not from speed but from that moment when the whole path finally resolves in your head before your hand even moves.
