Helpful details for a first message: iPhone model, iOS version, and the steps that led to the issue. A screenshot of the jar helps more than you'd think.

Common questions

How does fusing work?

Two identical planets that touch fuse into the next world up: Mercury → Venus → Earth → Mars → Jupiter → Saturn → Uranus → Neptune → Sun. The run ends when the pile stays above the dashed line for a moment, so keep the top of the jar clear.

What are combos?

A fusion that immediately causes another fusion starts a chain. Each link in the chain multiplies your score, up to ×3. Dropping a planet so it lands between two matching ones is the easiest way to start one.

What is StarDust and how do I earn it?

StarDust is the in-game currency for the three power-ups: Shake the jar, blast a Nova, and Fuse two planets. You earn it by fusing planets during play, and optionally by watching a short ad from the main menu. It is stored on your device only.

The "watch ad" button is missing or the ad won't load

Ads need an internet connection and can take a few seconds to fetch. If the button doesn't appear, check Wi-Fi or mobile data and try again after a moment. The game never blocks play behind an ad — you can always Play Again without one.

I watched an ad but didn't get the reward

Rewards are granted only when the ad plays to the end. If you closed it early, the reward is skipped by design. If it finished and you still got nothing, email us with the approximate time and we'll look into it.

I said "Ask App Not to Track" — will ads still work?

Yes. Ads still play and still reward you; they are just non-personalized. You can change the choice any time in iOS Settings → Privacy & Security → Tracking. Details are in the privacy policy.

My best score or StarDust disappeared

Progress lives only on your device. Deleting and reinstalling the app, or restoring the phone without an iCloud backup, starts you fresh. There is no cloud save in this version, so a reinstall cannot be undone by us.

Sound or vibration isn't working

Open the pause menu and check the sound, music, and vibration toggles. Also check the iPhone's silent switch and Settings → Sounds & Haptics → System Haptics.
