One Stroke!

One finger. One continuous stroke. Can you trace every line?

One Stroke! is a minimalist puzzle game with a simple rule: draw along every segment exactly once without lifting your finger. You can revisit dots, but you cannot trace the same segment twice.

A puzzle may look easy until you choose the wrong starting point. Look closely, plan your route and find the path that connects it all.

1,200 PUZZLES IN 15 STAGES
Start with simple shapes and work your way through increasingly complex networks of dots and lines. Later stages bring more segments and routes that require careful planning.

SIMPLE TOUCH CONTROLS
Drag your finger from dot to dot and watch your path light up. If you get stuck, restart the board and try another route.

HINTS WHEN YOU NEED THEM
A hint highlights a valid starting dot while leaving the rest of the puzzle for you to solve. The first three boards offer hints without watching an ad. On other boards, you can choose to watch a rewarded ad to unlock a hint.

CLEAN, MINIMALIST DESIGN
A bright background, clear lines and readable dots keep the focus on the puzzle.

PLAY AT YOUR OWN PACE
Replay boards, choose a stage and return to unfinished puzzles. Your progress is saved locally on your device. The puzzles work offline; ads and purchases require an internet connection.

OPTIONAL PREMIUM
The game contains ads and offers an optional one-time Premium purchase through Google Play. Premium removes ads and makes hints available without watching rewarded ads. All 1,200 boards are available without purchasing Premium.

Available in English and Polish.
