Cieline: One-Line Star Puzzle

Trace a single glowing line through every star — and watch a real constellation light up across the night sky.

Cieline is a calm, beautiful one-line puzzle. Connect all the stars in one continuous stroke, never lifting your finger and never crossing the same line twice. Simple to start, deeply satisfying to master.

• LIGHT UP REAL CONSTELLATIONS
Hidden through the journey are real star patterns — Orion, the Big Dipper, Cassiopeia, Lyra and more. Solve their level and the constellation ignites star by star, with a little piece of cosmic wonder to discover. Collect them all in your album.

• HUNDREDS OF HAND-TUNED LEVELS
A long Campaign that rises gently from your first easy loop to mind-bending Expert figures with only one or two real solutions and plenty of tempting dead ends.

• ENDLESS ARCADE
In the mood for a quick fix? Arcade mode generates fresh puzzles forever and tracks your best run.

• MADE TO FEEL GOOD
Soft starlight visuals, a deep night sky, gentle haptics, and a golden "comet" that sweeps across your finished figure. Unlock new sky themes as you progress.

• DESIGNED FOR CALM
No forced ads between every level. Play offline. One thumb, one screen.

Connect the stars. Light up the sky. Welcome to Cieline.
