Astrella: Star Battle Puzzle

Astrella is a minimalist, relaxing logic puzzle. Every day brings a new challenge — the same one for everyone.

Easy to learn, hard to master. Place stars on the grid following three rules:
– One star per row
– One star per column
– One star in each coloured region
…and no two stars may touch, not even diagonally.

Every puzzle has a single solution and is solved with pure logic — you never have to guess.
