The answeris No. The only way to purchase Gems is through the in-game Shop (processedsecurely by iTunes or Google).
There may bemany 3rd party websites and online marketplaces offering in-gamecurrency for Supercell games, but NONE of them are safe to use or verified bySupercell. It is best practice to ignore what these web places are offering orsaying, they are NOT affiliated or supported by Supercell. Often these thirdparties will ask for your Game Center/Google login credentials. This will givethem access to your game. If you give them your login, we cannot guarantee youraccount’s security.
If youpurchased gems from somewhere other than within the game, we cannot assist youany longer, as your account has already breached out Terms of Service.
We reservethe right to ban game accounts with Gem orders purchased outside the game.
