One Line Draw Game

One Line Draw is a spatial-reasoning puzzle built around a single rule: trace a path through every dot on the board without lifting your finger and without crossing the same line twice. Each level presents a small cluster of points, and your job is to find the one route through all of them that never backtracks over itself.

Levels start simple — a handful of dots in an easy pattern — and get trickier as the layouts grow more tangled, forcing you to plan your starting point and direction a few moves ahead instead of drawing on instinct. A single wrong stroke usually means starting the pattern over, so the game rewards patience more than speed.

Controls

Click and hold with the mouse to start drawing, then drag through the dots to trace your line. On phones and tablets, use the same motion with your finger.

Tips

• Scan the whole pattern before you draw — the correct starting dot is often one with only a single connecting path.
• Corner and edge dots with limited connections are usually the safest place to begin or end a line.
• If you get stuck partway through, trace backward from the last dot to see which path you missed.

It's a quiet, low-pressure puzzle game well suited to short breaks — no timer pressure, just one clean line to find.
