Star Battle

Place stars on the grid so that every row, every column and every outlined region contains exactly the same number of stars — 1 star on the 5×5 to 8×8 boards, 2 stars on the 10×10 board. Stars may never touch each other, not even diagonally.

• Tap a cell to cycle: empty → ✕ (no star here) → ★ star → empty.
• Right-click or long-press places or removes a star directly.
• Drag across cells to paint (or erase) ✕ marks.
• Keyboard: arrows move the cursor, Space cycles, X toggles a star, Ctrl+Z undoes.

Stars that break a rule turn red. Auto ✕ dots the cells your stars already rule out. Check highlights mistakes and Hint places one correct star. Every puzzle has a single unique solution.

Tips

Small regions are the key: a 3-cell region in a line forces its star into a very limited area. In 2-star puzzles, look for groups of regions that together fill a set of rows — they must contain all the stars of those rows.
