Download on theApp StoreAlso known as Queens, Hoshi, or Two Not Touch — if you've enjoyed those, you already know how to play.
One shared puzzle a day, growing from a quick Monday board to the full 10×10 two-star challenge on weekends. Keep your streak alive.
All 4,400+ puzzles are computer-verified to have exactly one solution reachable by deduction alone.
Stuck? The hint doesn't just reveal a cell — it explains the next logical step, so you get better every time.
From cozy 5×5 starters to expert 10×10 two-star boards, each in three difficulty levels. Pick any board, any time.
Mistakes never trigger ads. No lives, no energy, no paywalled levels. One optional purchase removes ads forever.
Beautiful pastel boards, full dark mode, auto-crossing around stars, undo/redo, drag to mark — and it all works offline.

Star Battle ("the app") is developed and published by the developer listed on our App Store page. This policy explains what information the app handles and how.
The app requires no account and no sign-in. Your puzzle progress, statistics, streaks, and settings are stored on your device. Streak and stats data may also be backed up to your personal iCloud key-value storage so a new device can restore it — this data lives in your Apple account and is not accessible to us.
The free version shows ads served by Google AdMob. If you grant the iOS tracking permission, AdMob may use your device's advertising identifier to show more relevant ads; if you decline, ads are shown without tracking. See Google's Privacy Policy for details. Purchasing "Remove Ads" removes all advertising from the app.
We use Google Firebase Analytics to collect anonymous, aggregated usage data (for example, which screens are used and how often the app crashes). This helps us improve the app and is not used to identify you.
In-app purchases are processed entirely by Apple. We never see or store your payment information.
The app is a general-audience logic game and is not directed at children under 13. We do not knowingly collect personal information from children.
If this policy changes, the updated version will be posted on this page with a new effective date. Questions? Email wuyuping38@gmail.com.
