A Logic Puzzle Game
Constellation
One crown in every row. One in every column. One in every region. No two touching. Map the sky, one careful placement at a time.
How to Play
Four rules. Infinite puzzles.
★
One star per row. Every row of the grid holds exactly one.
★
One star per column. Same rule, turned sideways.
★
One star per region. Each coloured zone gets exactly one, wherever it lands.
★
No touching. Not edge to edge, not corner to corner. Stars keep their distance.
