How to play
- Place one star in every row, every column and every colored region.
- Stars can't touch, not even diagonally.
- Tap a cell once to cross it out, twice for a star, three times to clear it. Drag to cross out several cells.
Every puzzle has exactly one answer, and you can always reach it by logic alone, no guessing. Stuck? Hint explains the next step.
Hints make a puzzle's stars silver: three stars for no hints, two for one, one for more.
