Common questions

My purchase is missing

Open Settings > Restore purchases while signed in to the same Apple ID or Google account you bought with.

How do I get a refund?

Payments go through Apple or Google, so refunds are requested from them: Apple, Google Play.

Are the other players real people?

No. Every rival is a computer character, and the game works without an internet connection.
