About One Stroke
One Stroke is a single-line path puzzle. Starting from the star, drag a continuous line that passes through every open square exactly once, weaving around the blocked tiles. Every board is generated from a real winding path, so a solution always exists — find it before the timer runs out as the grids grow from 4×4 to 7×7.
How to play
- Your line starts on the orange star.
- Drag into neighbouring squares (no diagonals) to extend it.
- Each open square must be visited exactly once; dark tiles are blocked.
- Drag back over the line, or press Z, to undo — grab the line anywhere to cut it there.
- Finish before the timer runs out; spare seconds become bonus points.
Objective
Cover every open square in one continuous line on all ten boards.
Tips & strategy
- Squares with only one open neighbour must be the end of your line — head there last.
- Hug the edges and corners early so you don't strand them.
- If a region gets cut off from the head of the line, back up right away.
