How can we help?

Cosmic Games is free on Google Play for Android and on the App Store for iPhone. Use the store buttons on the home page.

No. Most games work fully offline without an account. Sign-in is only required to submit scores to the global leaderboards, use chat, add friends and buy Stars.

Open the app, tap the Sign In button in the top right of the home screen. You can sign in with Google, Apple or email + password.

Play any game and complete the daily tasks in the Shop. Stars are the in-game currency (older versions called them gems).

All purchases go through Google Play Billing. You'll see Play's standard confirm-and-pay sheet. We never see your card details.

Go to cosmicgames.app/redeem, sign in with the same account you use in the game, and type the code. On Android you can also tap REDEEM A CODE on the home screen. Each code works once.

Open Google Play → tap your profile → Payments & subscriptions → Subscriptions → Cosmic Games → Cancel. Access continues until the end of your billing period.

Make sure you're signed in (top-right avatar icon). Pull down on the Online screen to refresh. If it still doesn't appear, check that you're on the latest app version.

Long-press the message in the lobby chat and tap Report. We review reports manually.

Open Friends from the home screen, go to ADD, and either scan your friend's QR code or type their friend code. They need to accept your request. You can only be added by someone who has your code.

Yes. Profile → tap your display name → enter a new one → Save. Changes appear on the leaderboard within a minute.

Try clearing the app cache: Settings → Apps → Cosmic Games → Storage → Clear cache. If it persists, reinstall. Email support with your device model + Android version.

Reset your password via "Forgot password" on the sign-in screen. If you used Google sign-in, confirm you're using the same Google account on this device.

Turn on "Reduce motion" in the Settings drawer. That disables heavy animations. Older devices may also benefit from closing other background apps.
