One star per row, column & region
⭐ Star Battle
Place stars so every row, every column and every outlined region holds exactly one star — and no two stars touch, not even diagonally. Puzzles are generated with a unique solution in three sizes.
How to play — Star Battle
Place stars so that EVERY row, EVERY column and EVERY bold-outlined region contains exactly ONE star.
Two stars may never touch each other — not even diagonally.
Tap once = ★ star · tap again = · dot (your “no star here” note) · tap again = clear. Tip: a region squeezed into one row uses up that row — every other cell of the row gets a dot.
Tap cycles: empty → ★ → · (impossible mark) → empty. Stars that clash (same row/column/region or touching) turn red. Use dots to mark squares a star can never occupy.
