How to play

Drag to aim and lift to drop. Two matching bodies merge into the next size. Keep settled planets below the jar's rim. A new black hole swallows nearby smaller bodies; two black holes make a Big Bang and clear the jar.

Where is my progress?

Your jar and collection are saved on your current device or browser. Choose Continue to resume a saved jar. Each app and the web game keep separate saves, and progress doesn't sync between devices.

A private browser window, clearing website data, clearing the app's storage, or deleting the app can remove progress. If your progress is missing, avoid clearing data or reinstalling while you ask for help. We don't have a server copy to restore.

Sound and interruptions

Check the Sound effects and Ambient music controls in Settings on iPhone and iPad, or the Sound and Music switches on the home and pause screens on Android and the web. Then check your device's media volume and audio output. The iOS app plays audio with the silent switch on. The game pauses when the app goes into the background or audio is interrupted.

Daily Jars and constellations

Classic and Daily Jar merges both count toward your constellations. Making Earth in a Daily Jar earns a stamp for that date. Missing a day doesn't remove progress, and replaying a date keeps its best score and one stamp.
