Constellation

Light up the night sky. Place a star in every row so that no two stars share a row, column, or diagonal. A few stars are fixed to start you off, and there's always a valid arrangement. Bigger skies each level.

How to play

1. Tap a square to place or remove a star. Gold stars are fixed clues.
2. No two stars may share a row, a column, or a diagonal.
3. Place one star in every row (n stars total) with no conflicts to solve it. Red stars are attacking each other.
