How do I play?
Place exactly one star in every row, column and colored region. Stars must never touch, even at a corner. In Two Stars puzzles, every row, column and region needs two stars. Tap a square to mark an X, tap again for a star, and again to clear it. The "How to play" button in the app shows the same rules.
What is Auto-cross?
Auto-cross marks the squares ruled out by your stars. You can switch it off in the puzzle menu.
I made a mistake
Use Undo for your last move, or Hint for one step. If some marks conflict, the app highlights the squares involved. "Clear marks" in the puzzle menu resets that puzzle.
When do new daily puzzles arrive?
A fresh set of daily puzzles (Easy, Medium and Hard) arrives at midnight by your device's clock. Practice puzzles are available at any time.
Where is my progress saved?
Only on your iPhone. There are no accounts, so progress does not sync to other devices, and deleting the app deletes it. See the privacy policy for details.
