Draw. Drop. Guide it home.

One Line is a beautifully minimal physics puzzle. Each level gives you a glowing ball, a goal portal, and a single resource: a line of light you draw with your finger. Sketch the perfect ramp, release the ball, and let gravity do the rest. Simple to pick up in seconds — and quietly addictive for hours.

No timers screaming at you. No clutter. Just you, a falling ball, and one elegant line standing between it and home.

— HOW TO PLAY —
â€ĸ Draw a line anywhere on the screen with your finger.
â€ĸ Tap DROP to release the ball.
â€ĸ Roll, bounce, and curve your way into the glowing goal.
â€ĸ You only have so much ink — make every stroke count.

— WHY YOU'LL KEEP PLAYING —
â€ĸ ONE-FINGER CONTROLS. If you can draw a squiggle, you can play.
â€ĸ A SMOOTH DIFFICULTY CURVE. The first levels are a gentle warm-up; later levels add spikes, moving hazards, tight ink budgets and shrinking goals that will test your timing and your geometry.
â€ĸ HUNDREDS OF LEVELS. Procedurally generated and endless — there is always one more.
â€ĸ DAILY CHALLENGE. A brand-new puzzle every day, the same board for everyone. Build your streak.
â€ĸ COLLECT STARS. Thread the trickiest path to grab every star and earn more coins.
â€ĸ UNLOCK SKINS. Spend coins on glowing ball and ink styles in the Shop.
â€ĸ SATISFYING JUICE. Particle bursts, screen shake, glow trails and crisp haptics make every win feel great.
â€ĸ A GORGEOUS NEON LOOK. A calm deep-space palette with a warm glowing ball — 100% hand-tuned, no clutter.
â€ĸ PLAYS OFFLINE. No account, no sign-up, no internet required to play.

— ONE MORE TRY —
Missed by a hair? Erase, redraw, and go again in a single tap. One Line is built around that "just one more" loop: every failure is a quick lesson and the next attempt is two seconds away.

Free to play, supported by optional ads. Watch a rewarded ad for extra ink or a hint only if you choose to — never required to progress.

Can you guide every ball home with a single line?

Draw it. Drop it. Nail it.
Draw a glowing line, drop the ball, guide it home. Easy to play, hard to master.
