One Line: Draw Brain Puzzle

✏️ 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. That one rule is the whole game, and it's harder to satisfy than it sounds. Learning it takes a moment. 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 🧠 A BRAIN PUZZLE, NOT A RACE • 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 — no connection needed • 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 📅 A NEW SHAPE EVERY DAY The same daily board goes out to everyone, so you can see how you did against everyone else who drew it. Miss a day and you can still go back and play it. If you like logic puzzles, drawing games, or anything that asks you to think a few steps ahead before you move, this one is for you. Trace, think, undo, and try again — one line at a time. Free to play, supported by ads.
