Something not working, or an idea for the game? Here is how to reach a person.
Open Arkadia and go to Settings → Support. A ticket from inside the app arrives with your app version attached, which is usually the first thing we would have to ask for — and the reply appears on that same screen, so nothing gets lost in a spam folder.
Arkadia stores everything on your device by default, so uninstalling the app or losing the phone removes it. Connecting an account from Settings → Account is what protects against that, and it is worth doing before you have anything you would miss.
Open Settings and use Restore purchases. A purchase interrupted by a crash or a dead network is delivered the next time the app checks. If that does not work, send a ticket with the date and the pack you bought.
Press the name on the leaderboard to report it. We read every report, and we can suspend an account — which removes that player from every board immediately. You will see what we did in Settings → Support.
Settings → Delete my account. It removes your data from our servers first, then everything on the device. It cannot be undone.
