If you are in need of more diamonds to speed up production, complete upgrades or buy items in Hay Day, the only authorised way to buy diamonds is through the in-game shop which runs via iTunes and Google Play.
There are several third party websites and apps that offer in-game currency for Hay Day, but none of these are safe to use or authorised by Supercell. Often these third parties will ask for your Game Center or Google Play log-in credentials. This means they will be able to access your game, and we can no longer guarantee the security of your account.
In case you purchased diamonds from somewhere other than through the game, we unfortunately cannot assist you any further as your account is already in breach of our Terms of Service.
We reserve the right to bangame accounts with diamond orders from third-party websites.
