Frequently Asked Questions
Do I need an account or login to play?
No. Stellarfall requires no account, sign-up, or login. Just open the app and start playing.
Does the game work offline?
Yes. Stellarfall plays fully offline — no internet connection is required to play any mode.
How do I play?
Drop cosmic bodies into the well and merge two of the same kind to forge the next one up the ladder — shards become asteroids, moons grow into planets, stars collapse into a pulsar, and so on up to the black hole. Keep the board from overflowing as you climb.
What are the different modes?
- Classic — the pure climb; reach the black hole to win.
- Supernova — a 3-minute time attack; score as high as you can.
- Nova Rain — survive a steady storm of shards.
- Collapse — the walls close in; merge fast.
- Zen — no timer, no game over; just drop and drift.
How are my scores saved?
Your best score for each mode is saved locally on your device. There is no account, so scores stay on the device where you play.
Is the game free? How do ads work?
Stellarfall is free and supported by ads. On iPhone and iPad, ads are non-personalized and the app does not ask to track you across other apps or websites. You may occasionally see an optional "Continue" that rewards you with a second chance after watching a short ad — that's always your choice and never required.
I lost my progress or my score reset.
Because scores are stored on your device, reinstalling the app or switching devices starts you fresh. If a score reset unexpectedly on the same device, email us with your device and iOS version and we'll look into it.
