Did you upgrade to one of the iPhones 6 or iPhones 6s?
If you're not familiar with Clash of Clans, it's a a game where you build forts with gold and elixir resources. Buildings are dragged and dropped however players like, and resources are collected and stored whenever you hop into the game. Over time, they build an army of various troop types. They can be taken on single player missions to raze the villages of nearby goblins, or on raiding parties of neighboring villages. Similarly, other players can raid your town, but don't worry, nothing is permanently destroyed (though they can snatch some of your gold and elixir). Players earn and lose trophies through their multiplayer raids, and band together in clans in order to concentrate their attacks.
It sounds simple, but there's a lot more to it. And we're here to help!
