One Go Line Puzzle

One Go Line Puzzle, from Mad1 Games, builds an entire game around a classic pen-and-paper brain teaser: trace a shape in a single continuous stroke. It is a minimalist puzzle game meant for short bursts of play, where the challenge comes from planning a route rather than from speed or reflexes.

The rules fit in a sentence. Each level shows a figure, and you have to draw over all of it without lifting your finger. Crossing back over a line you have already drawn ends the attempt and counts as a failure, while completing the whole outline in one pass clears the stage. Levels get harder as you go, so early figures can be solved almost by instinct, whereas later ones require thinking about where to start and which paths to save for last. The developer frames it as easy to learn but tricky to master, and the description suggests nothing beyond this core idea: no timers, story or extra modes are mentioned.

The game is well received, averaging 4.5 from about 28,500 ratings; 77% are five stars and 6% are one star. It has passed 5,000,000+ installs. It is free but ad supported, and in-app purchases cost between R$10.99 and R$27.99 per item. It was updated on 2026-09-08, requires Android 7.0 or newer, and is rated All ages. We list a single version, 1.8, and the record does not give a download size.

Puzzle fans who like calm, logic-based challenges that fit into a coffee break will enjoy it. Players looking for variety beyond one mechanic may tire of it quickly.
