About
A calm daily logic puzzle in the night sky.
Every day, a new constellation waits to be drawn. Connect the numbered stars with light-bridges until the whole sky becomes one shape. Each star's number tells you how many bridges must touch it. Bridges run straight, never cross, and there is always exactly one solution, reachable by pure logic with no guessing.
One board a day, the same for everyone, so you can compare your time and share your result.
- A fresh puzzle every day, hand-verified to have a single logical solution.
- Time-based scoring, daily streaks, and Game Center leaderboards.
- Learn-by-doing onboarding, then a gentle-to-expert weekly curve.
- A quiet, premium night sky that drifts warmer in summer and cooler in winter.
- Colorblind-friendly by design: numbers and lines, never color alone.
- Free, with no banner ads and no interruptions. The first hint each day is free; extra hints come through an optional rewarded video. A coffee tip unlocks extra sky palettes and more daily hints; the daily is always free.
No timers pushing you, no clutter, no noise. Just you, the stars, and a clear line of logic.
