One Stroke

Play One Stroke free online. Trace every path on the board in a single continuous stroke. A focused, minimal browser puzzle with no download.

One Stroke is a drawing puzzle with one rule: you cannot lift your finger. Every line on the board has to be traced exactly once, which turns a simple shape into a small route-planning problem.

How to play One Stroke

1. Start from a point and drag to draw along the paths.
2. Cover every line without lifting your finger.
3. Complete the whole figure to clear the level.

Tips and tricks

• Begin at a corner with an odd number of lines — most puzzles need it.
• Plan the last three lines before you start drawing.
