Light up real constellations
Only for iPhone
Free
iPhone
Draw one glowing line, connect every star, and watch real constellations ignite. Relax in calm mode or test your mind on Expert. New constellations to collect!
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.
