About this game

You stare at the grid. There's a path in there somewhere. You just have to find it — in one continuous line, without lifting your finger once.

That's it. That's the game.

Just One Line is a one-stroke puzzle game built around satisfying feelings in gaming.


HOW TO PLAY

• Swipe to draw a line drawing that passes through every dot on the grid
• Don't retrace a path.

No timers. Just a clean logic puzzle and your brain.


GAME FEATURES

• Handcrafted one-touch puzzle levels, from gentle to genuinely tricky
• Smooth, minimal design — this is a minimalist puzzle game that gets out of your way


WHY IT WORKS

Every puzzle is a small exercise in spatial reasoning. You're not tapping randomly — you're planning, backtracking, and thinking a few moves ahead. That kind of focused logical thinking is what makes brain teaser games genuinely good for your mind.

If you enjoy connect the dots, flow puzzle games, or classics, you'll love this. Just One Line sits in that same family of quiet, absorbing mind games — the kind you play during a commute and somehow lose an hour to.

Draw smarter. One line at a time.
