We're aware of an issue with Facebook purchases for all King Games and our team is on it. 🛠️ Hang tight while we fix things! You can still enjoy the game, and we'll keep you posted once it's solved.
Can you let us know what happens when you try to buy gold or ask friends for help? I mean, does the game freeze, do you get any pop up errors. Its kind of hard to help without knowing a bit more sorry!
