Puzzle game. Graph theory. Draw One Line is pure logic in vector form. One continuous path. All edges. No repeats. Simple rule. Deep challenge.
How to Play Draw One Line
Trace a path. Cover every edge. Never lift your finger. Your goal is simple: complete the figure in one continuous line without retracing any segment.
The Core Mechanic
Tap the glowing node. Start tracing. Move along edges to neighboring nodes. Keep your finger down. Release early? The figure resets. No second chances mid-draw. Finish the path or start over.
Progression System
Start with basic shapes. Unlock complex graphs. Objects. Nature. Architecture. Transportation. Space. Each level is a new geometric puzzle. Beat it on first try? Earn 3 stars. The difficulty ramps hard.
Strategy Tips
Plan before you draw. Count odd nodes. Odd nodes determine starting points. More than two odd nodes? Impossible puzzle. Look for symmetry. Exploit it. Master Eulerian paths without knowing the math.
