DrawLine: One Stroke Puzzle

Can you trace it without lifting your finger?

DrawLine is a one-stroke tracing puzzle where every level is a tangle of
glowing lines — and your job is to trace all of them in a single,
unbroken stroke. Lift too early, and you start over.

• ENDLESS LEVELS — Infinite hand-crafted-feeling puzzles, each one
guaranteed solvable in one stroke, no matter how tangled it looks.

• BOSS LEVELS EVERY 10 — Every 10th level is a genuine wall: dense
intersections where one wrong turn strands you. Beat it, or watch an
ad to skip and keep climbing.

• YOUR OWN IQ SCORE — Every level scores your Line IQ based on speed and
how clean your solve was. Chase Doodler → Sharp Mind → Line Artist →
Physics Wizard → Line Genius.

• FOUR SEASONS OF SCENERY — Every level is set against a shifting
Spring, Summer, Autumn, or Winter backdrop.

• 14 ACHIEVEMENTS — From your first clear to Boss Hunter, Speed runner,
and Certified Genius.

• FAIR LIVES SYSTEM — 3 free lives, one regenerates every 5 minutes, or
watch a quick ad for an extra life or a boss skip when you're stuck.

No sign-up. No paywall. Just you, a glowing tangle of lines, and one
stroke to solve it.
