What does two stars never touch mean in Star Battle?

It is Star Battle's signature rule. Every pair of stars must keep at least one full cell of distance in every direction. They cannot share an edge or touch diagonally, so each star is surrounded by clear space. Combined with one star per region and the required stars per row and column, only one arrangement fits.

How is Star Battle different from Sudoku?

Star Battle uses coloured irregular regions and a no-touching star rule instead of Sudoku's 3x3 boxes and number placement. Every row, column and region needs the required number of stars, and no two stars may touch. The deduction feels distinct: spatial, calm and deeply satisfying.
