One Line Parking – Free Puzzle Game on CoolStickerLab

One Line Parking is a spatial logic puzzle that wraps a parking lot into a one-stroke drawing challenge. Your goal is to trace a single continuous line that visits every parking spot exactly once without lifting your finger or crossing your own path. Each level adds more cars, tighter grids, and trickier entry and exit constraints, turning a simple concept into a satisfying brain workout. The game introduces Hamiltonian path thinking without ever feeling academic — you learn topology and planning by feel. With hand-crafted levels that gradually escalate in difficulty, One Line Parking is perfect for puzzle fans who like quiet, contemplative challenges.

How to Play

Drag from the starting point and trace a path that touches every car without retracing or crossing. Reach the exit to complete the level.

Skills Trained

Spatial planning, Hamiltonian path logic, topological reasoning, and patience.
