About Star Battle
Place stars to match the required count in every row, column and outlined region. Stars cannot touch, even at a corner. Use the borders to narrow down their positions.
How to play
- Goal
- Place stars so every row, column and constellation holds its count.
- How it ends
- A chart is solved when every count is met and no two stars touch, even diagonally. There is no way to lose.
- Record
- The fastest first solve of each chart, with its holder's name.
- Tap a cell to veil it (your mark for “no star here”), tap again to set a star; drag to veil a run of cells.
- Every row, column and gold-walled constellation holds the same number of stars: one on ★ charts, two on ★★ charts.
- No two stars touch, not even diagonally — a star veils the eight cells around it for you.
