It's a very nice game, no doubt but after playing more than 2000games, I just realised that you can't win and level up in this game after a certain point of level you reach, until and unless you pay and purchase boosters, no matter how hard you try...and moreover you are gonna definitely loose those matches played with those booster which you have purchased with coins, it's a very addictive game but don't waste your money and time and most important don't expect win win situation in this game...
