It is popular stregetic game which is very addictive. This game is played all over the world . In this game players makes clans in which many members are added and they can chat anything. They used to have clan wars too. The graphics of the game is preety good and so the players who plays this game becomes very addicted to this game . The features and functions are good enough. But the usefulness is 0 . It is very very addictive and there is a mental pressure for the students and adults too . The students cannot pay attention to their studies and many people buys gems and coins using money . So I reccomend not to play this game
