Star Battle
Place stars so every row, column, and region holds exactly one — with no two stars touching.
The rules
How to play
- 01
The grid
Star Battle is played on a square grid divided into colored regions. Each region is an irregular shape you must satisfy alongside the rows and columns.
- 02
One star per row
Place exactly one star in every row. No row may hold two stars, and none may be left empty.
- 03
One star per column
The same rule runs vertically: each column contains exactly one star, top to bottom.
- 04
One star per region
Every colored region must also hold exactly one star. Rows, columns, and regions all have to balance at once.
- 05
No touching
Stars can never be adjacent — not horizontally, not vertically, not even diagonally. Placing one clears all eight neighbouring cells.

Six habits of star hunters
Mark the impossible
Use the ✕ mark to block cells that can never hold a star. Eliminating options is half the puzzle.
Corner regions first
Small or tightly boxed regions often have only one or two legal cells — solve those to seed the board.
Count what remains
When a row, column, or region has a single valid cell left, that cell must be a star.
Block after placing
Every star forbids its eight neighbours. Mark them immediately to keep the board honest.
Cross-region logic
If a region's cells all sit in one row, that row's star must live inside the region — freeing the rest of the row.
Look for overlaps
Where a region hugs a single column, it constrains both — chain those deductions to break the puzzle open.
