What is Clash of Clans?
Clash of Clans is an Apple IOS game/application(hopefully it'll be on Android soon) that allows players to build up epic bases with mobile devices such as iPads and iPhones
while stealing resources from other bases with the troops they have upgraded and amassed. The resources stolen help
fund upgrades on the recieving player's base and to help create more troops for future skirmishes.
Clash of Clans base defense strategies are a big part of the game due to the desire to keep other player's away from your resources. When you've spent millions of gold and elixir on your carefully planned base you want to ensure it's performing as well as possible for what you are trying to accomplish.
