Hell guys, today I am going to write a review on clash of clans, this is very good game, I love it. The concept of game is very good, build your clan, attack enemy base and steal resources and update your base, make your clan chait with other clanmates and also donate troops and help each others.Layout and design are also very good, music of game is awesome and control icons are great so overall interface of game is very good.Features and functions of game is also very good for exp : save your progress with google play games, change language, on- off music, chang your nams, etc. What can I say about usefulness, it is useful in free time and when you are bored. It’s a best time killer game and very addicted. game.
