Clash of Clans is a management RTS. Here, you'll find a village where the members of your fearless clan reside. Then, you get to send them out into the world to face missions and prove their courage while destroying enemy camps.
Divided into two completely different stages, you start out by building structures and hiring citizens (yup, you have to pay them). Later on, you get the chance to participate in real-time strategy battles where you can show off your skills.
With ten different types of units, you can build up your strategy by gaining experience and money. Defense systems must also be developed for your city and are vital if you expect to withstand the brutality of oncoming enemy attacks.
Given its viral success, Clash of Clans is obviously a very entertaining game with classic management strategy gameplay that's far more unique than might initially be guessed. Plus, it's completely free and totally optimized for Android.
