The game is good . If you are searching for exciting and interesting game one of the best option is clash of clans.
But if you are a student , I will recommend you not to play this game because you will not able to concern in your exams. I am telling about my experience, I had played for 3 years as a result , I got only passing marks in my class 10th exam. That's too bad for me. now finally I left the game too hardly.
But if you don't have any problem about your studies, The game is best with exciting clan wars , clan war league , separate clan feature where you can talk with other members friendly and work together to promote your clan.
