Monoline — Draw in One

One unbroken line. Trace every edge exactly once and the shape comes alive. Simple to start, impossible to put down — now with daily puzzles and neon themes.

Draw the whole shape without lifting your finger.

Monoline is a beautifully minimal one-line puzzle game. Every level is a shape made of connected edges — your job is to trace all of them in a single unbroken stroke, never crossing the same line twice. Get it right and the shape lights up.

It's the kind of puzzle that's obvious in five seconds and satisfying for hours.
