I bought coins but they didn't show up.
Open the coin shop and tap "Restore purchases" — this re-checks your purchase history with Apple/Google and re-credits anything that didn't land. If that doesn't fix it, email us with your player ID (Menu → Help & about) and the approximate time of purchase.
How do I delete my account/data?
Open Menu → Help & about in the app to see your Player ID, then email us with it and we'll remove your records — see our Privacy Policy for details.
A name or word on the leaderboard is offensive.
