ONE LINE – One Touch Puzzle for Android

Looking for a quick brain workout you can play anywhere? This page offers the ONE LINE APK download for Android, the latest version 2.6.8 packaged as an XAPK. Developed by Infinity Games and released free on Google Play, ONE LINE has passed 100,000 downloads worldwide and holds a solid 4.6 out of 5 rating.

What ONE LINE Is and How It Plays

Each level shows a geometric figure made of dots and lines. Your job is to trace the whole figure in one continuous stroke, never lifting your finger and never retracing a line.

It sounds easy, but the real challenge is choosing the right starting point and finding a path that passes through every dot. Every puzzle rewards a bit of planning, logic and spatial thinking before you start drawing.

Touch controls are as simple as they get, and the clean, minimal look keeps you focused, making it ideal for short sessions during a break or commute.

Levels, Hints and Progress Tracking

The game packs a large number of short, varied levels built around different geometric patterns. Early puzzles ease you into the idea, while later stages grow noticeably trickier.

Some levels add movement restrictions and special paths that raise the difficulty. When you get stuck, hints help you find a shortcut toward the solution.

As you play, ONE LINE shows performance charts and IQ-style results, so you can see how your logical skills develop over time.

ONE LINE runs on Android 8.0 or newer, and the download is about 74 MB. It is light on storage and battery, and it works fully offline once installed.
