## What is One Line?

One line. Every path. Never lift your finger.

Pick a dot, follow the lines, and see if you can cover a whole shape in a single unbroken stroke. Every line has to be drawn exactly once — no more, no less.

The rule takes a moment to learn. Getting good at it takes a while longer, and that's the part worth staying for.

WHAT YOU'LL DO
• Trace a shape from end to end without lifting your finger
• Look before you draw — the dot you start from is half the answer
• Back up a line and try another way whenever a path runs out
• Meet a new twist now and then, and meet it again when it counts

BUILT FOR THINKING, NOT RUSHING
• No countdowns, no lives, no streak to lose in a hurry
• Come back to a board you've already solved and do it cleaner
• A puzzle is never a wall — there's a nudge waiting when you want one
• Worlds open one after another, each a little heavier than the last

QUIET BY DESIGN
• Plays offline, wherever you happen to be
• One hand, one finger, a minute at a time
• No account, no sign-up, nothing to set up first
• Soft night colors and quiet sound, both easy to turn off

Free to play, supported by ads.
