Star Battle basics

Think of it as a tiny placement puzzle: the whole board needs 7 stars, but the rows, columns, color areas, and neighbors all restrict where they can go.

  • Place exactly one star in each row.
  • Place exactly one star in each column.
  • Place exactly one star in each color region.
  • Stars may not touch, including diagonally.
