Frequently asked questions
How do I remove ads?
Open the shop and choose “Remove ads”. It's a one-time purchase that removes interstitial ads. Optional reward videos (“Continue”, “x2 coins”) remain available if you want to watch them.
I switched iPhone / reinstalled: how do I restore my purchase?
Go to Settings (the gear in the menu) and tap “Restore purchases”. Sign in with the same Apple Account used for the original purchase.
My scores and coins are gone
