About this game

Begin under an empty sky and slowly bring forgotten constellations back to life.

Constellation Lines is a calm astronomy puzzle game where you trace real star patterns by connecting points of light. Every constellation is based on authentic astronomical data, including real star positions, brightness, and celestial coordinates. Some stars belong to the figure. Many do not.
Draw one line at a time and discover shapes that people have imagined in the night sky for centuries.

The game includes 24 real constellations divided into two progression packs:

- Northern Sky
Explore familiar figures from northern skies, including Ursa Major, Orion, Cassiopeia, Draco, and more.

- Southern Sky
Unlock constellations visible from the southern hemisphere, including the Southern Cross, Hydra, Pavo, and other distant formations.

Each pack begins with simpler patterns and gradually introduces larger and more intricate constellations.

Touch a star and drag toward another to create a line. Use pinch controls to zoom and move across the star field with two fingers. If you make a mistake, erase lines with a quick gesture or switch to single-tap erase mode. When your drawing matches the hidden constellation, the figure is revealed and added to your observatory journal.

Features:
• Trace 24 real astronomical constellations
• Stars use authentic brightness and sky coordinates
• Calm puzzle gameplay focused on observation
• Northern and Southern sky progression paths
• Daily constellation challenges with rotating patterns
• Earn points for accuracy, speed, and fewer hints
• Three hint types for different play styles
• Offline play with no accounts or ads
• Minimal interface and slow atmospheric pacing

Every completed constellation unlocks a page from an old observatory diary written by Margarete, an astronomer reflecting on the quiet beauty of the sky. These short entries accompany your progress and slowly build a peaceful collection of observations and memories.

Constellation Lines is designed as a relaxed stargazing experience. There are no timers pushing you forward, no streak systems, and no interruptions. The night sky waits patiently while you explore it at your own pace.

From the seven bright stars of Ursa Major to the long shape of Hydra, every puzzle is inspired by real constellations known across generations of skywatchers.

Look up. Connect the stars. Draw the night sky.
