One Line is a free puzzle game you can play right here in your browser. The core of it is puzzle and drawing & art. There is no sign-up, no launcher and no wait — press play and you are in.
About One Line
A brain-training puzzle in which you draw 1 line, that will sharpen your wits. In this free-to-play puzzle game, you merely have to draw one line. It is deceptively simple, yet profoundly deep. Play through the extensive stages, sharpening your wits as you have fun.
How to play One Line
There is very little to learn before your first run. The controls are listed in full in the table below — there are only a handful of them. Portrait layout: hold the phone the way you normally do, or play it centred in the page on desktop. If a round goes badly, restart — attempts are cheap and it is usually the fastest way to improve.
Controls
| Input | Action |
|---|---|
| Mouse | Select and drag pieces |
| Left click | Confirm a move |
On mobile: Tap and swipe directly on the screen. The game is built for portrait, so you can play one-handed without rotating your phone.
Why it is worth playing
One Line is easy to start and harder to master, which is the balance the best browser games hit. A browser game does not need to be more than that.
