Before you write

I bought the full game. How do I get it on a new phone?: Sign in to the same Google account, open Settings, then App, and tap Restore purchase.
How do I get a refund?: Payments go through Google Play, so refunds do too: see Google Play's refund help. If it cannot help, write to us with your order number (it starts with GPA.).
