About One Line Draw

Unico Studio, whose other Poki games include the Brain Test series and Word City, made One Line Draw as a single-stroke drawing puzzle. It was released in April 2025. Each level shows a grey outline made of straight segments joined at coloured dots, and you have to trace every segment in one continuous line. You may not lift off and start again elsewhere, and you may not run over a segment you have already covered.

How to play

Press and hold the mouse button on a dot, then drag along the outline; each segment you complete turns orange. On a phone or tablet you do the same with your finger. The very first puzzle is a five-pointed star, and an animated hand shows the motion before you try it. A counter at the top of the screen tracks progress, starting at 0/5 on that star, which has five segments to cover.

The trick in most puzzles is where you begin. Some dots work as a starting point and some leave you stranded with a segment you can no longer reach, so it pays to study the shape before your first drag.

Lives, undo and skip

You have three lives, shown as yellow dots next to the level name. Pressing Retry or drawing a stroke that does not match the outline costs one of them and greys out a dot. When all three are gone, the game-over screen offers a Revive button that refills your lives after an ad.

Two helper buttons sit under the puzzle:

• Undo removes your most recent segment, after a short rewarded video.
• Skip jumps past the current level, also after a video. Skipped levels are marked on the level select screen so you can come back to them later.

Level select and progress

Levels open one after another and are laid out in pages of numbered buttons, with locked levels shown by a padlock icon. Your progress, your skipped levels and your remaining lives are saved in the browser, so you can close the game and continue later.

Tips

• Count how many segments meet at each dot. If an odd number meet at a dot, your line must either begin or end there, so start from one of those dots.
• Do not rush to press Retry when you get stuck, because it costs a life just like a wrong stroke.
• Use Skip on a level that has you stuck, then return to it later from the level select screen.
