How to play Star Battle (Two Not Touch)
Star Battle, also called Two Not Touch, is a placement puzzle. You place stars so that every row, every column and every outlined region contains exactly one star, and no two stars touch each other — not even diagonally.
- 1One star per row, column and region. Every row, every column and each outlined region must contain exactly one star.
- 2Stars can't touch. No two stars may be adjacent, including diagonally — every star needs a clear ring of empty cells around it.
- 3Mark blocked cells. Tap a cell once to place a star, again to mark it blocked (no star), and again to clear it.
- 4Use small regions. A region that fits in just a couple of rows or columns sharply limits where its star — and the surrounding stars — can go.
- 5Solve fast for points. Place all the stars correctly as quickly as you can to earn a speed bonus.
Tips & strategy
Look for regions squeezed into a single row or column band — their star placement forces empty cells across whole lines, which then constrain neighbouring regions. Marking blocked cells around each placed star is the key habit; the no-touch ring often solves adjacent regions for you.
