Place the stars so each row, column and outlined region holds its exact quota, and no two stars ever sit side by side.

How to play
Star Battle is a logic puzzle on a gridded board split into irregular regions. You must place a fixed number of stars in every row, every column and every region, and no two stars may touch, not even diagonally. Each puzzle has exactly one solution.
Every row, column and region needs the same star count (one or two, depending on the board).
Stars are never adjacent, so a placed star rules out all eight surrounding cells.
Mark cells you have eliminated with an X to keep your deductions straight; solve it when all stars are correctly placed.
Controls
Desktop: click a cell to cycle empty → star → X note → empty. Right-click jumps straight to an X note (or clears one).
Phone & tablet: tap a cell to cycle through star and note, no keyboard needed. Use the Hint and Reset buttons any time.
Game modes
Sizes, 6×6 with one star per line, 8×8 with one star, and a tougher 10×10 with two stars per line.
Daily, one shared puzzle each day.
Practice, endless fresh boards on demand.
Tips & strategy
Hunt for small regions: a region that barely fits its stars sharply limits where they go.
Use the no-touch rule aggressively, each placed star eliminates a whole ring of neighbours, often forcing the next move.
When a row or column already has its full count, X out every remaining cell in that line.
