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.
Remember that the maximum amount of lives that you can have is 5. So if you're clicking this link when you have lives, it won't work. You need to click it when you're on 0 lives. But... where are you seeing this link because I haven't seen it, haha.
