Quarko is a calm collection of puzzle games in one app, spanning optics, magnetism, cellular growth, colour perception, deduction, graph logic, and more. Tap any game to open its levels or its endless mode.
Each game has a hint button. Hints cost Quanta, the calm currency you earn by clearing levels, keeping a daily streak, and opening the daily chest.
Quarko Complete is one optional one-time purchase. It makes every hint free and doubles your daily chest. Everything else in Quarko is free, and there are no subscriptions.
Open the store panel inside the app and tap "Restore purchase". As long as you are signed in with the same Apple or Google account that made the purchase, it will unlock again at no charge.
Quarko has no reset button. To start over, delete the app and install it again: this removes everything it saved on the device, including the random identifier described in the Privacy Policy. On Android, if your phone backs up app data to your Google account, installing again can bring your progress back; to start fresh there, clear Quarko's storage in your phone's settings instead. Quarko Complete comes back with "Restore purchase".
Open Settings and choose a language. Quarko is available in English, Italian, Spanish, French, German, and Brazilian Portuguese, and follows your device language by default.
No. Every game plays without a connection. When you are online, the app also talks to Google Firebase for usage statistics, crash reports, remote settings, a check that it is a genuine copy, and reminders, as described in the Privacy Policy. Purchases and restores go through the App Store or Google Play.
