What is One Line Draw
One Line Draw is a brain-teasing puzzle built on a beautifully simple rule: trace an entire shape using a single, unbroken line, without lifting your finger or going over the same segment twice. Each level hands you a shape made of dots and connecting lines, and it is up to you to find the one path that covers every line exactly once.
It is rooted in a classic mathematical idea — the Euler path — but you do not need any math to enjoy it. Early levels ease you in with simple shapes, yet they quickly grow into tangled webs that demand real planning. The moment you commit to a route, a single wrong turn can leave you stuck with an unreachable line, so thinking ahead matters far more than speed.
With hundreds of levels that ramp up in difficulty, it is a perfect pick-up-and-play brain teaser. There is no timer and no pressure, just the quiet satisfaction of finding the clean solution that makes every line fall into place.

How to Play One Line Draw
Each level shows a shape made of connected lines and dots. Your goal is to trace over every line in the shape using a single continuous stroke, without lifting your finger or retracing any segment. Drag from one dot to the next to draw, and plan your route carefully — once you commit to a path, you cannot redraw a line. Solve the shape to unlock the next, increasingly complex puzzle.
Controls
Click and drag from one dot to an adjacent dot to draw a line, then keep dragging to extend your path through connected dots without lifting. On mobile, touch and drag to draw.
Strategies
Look for dots with an odd number of connected lines first — these must be your start or end points. Mentally trace your entire route before drawing, because a single wrong segment can dead-end the puzzle. Some shapes have multiple valid solutions.
Why is One Line Draw So Popular
One Line Draw hooks players because every puzzle feels like a small, self-contained mystery. The rule is instantly understandable — one line, no repeats — yet cracking a complex shape delivers a genuine rush of cleverness. It is also endlessly replayable across hundreds of levels, and the absence of timers or penalties makes it as relaxing as it is challenging, a combination that keeps curious minds coming back for just one more shape.
Tips and Tricks
Find the odd-degree dots first
Count how many lines connect to each dot. Any dot with an odd number of connections must be either your starting point or your ending point — a fundamental rule of these puzzles. Lock those down first and the rest of the route falls into place far more easily.
Mentally trace before you draw
Before committing, trace the whole path in your head. A single segment drawn the wrong way can dead-end the entire puzzle, and there is no partial undo. A few seconds of planning saves a full restart.
Save tricky branches for the end
If one part of the shape looks like a dead-end loop, leave it for the final stretch of your path. Drawing it early can trap you away from the rest of the shape, while saving it lets you weave in and out cleanly at the finish.
Pause at every intersection
When several lines meet at one dot, the path you choose through it really matters. Stop at every junction and picture where each option leads — the wrong fork at a busy intersection is the most common way runs end.
Remember there may be multiple solutions
Some shapes have more than one valid single-line path. If your usual approach stalls, try starting from a different odd-degree dot or tackling the shape in reverse — a fresh angle often reveals a route you missed.
