DON'T WASTE YOUR MONEY THIS IS A HUGE WASTE I hate that you have a short time limit and then you loose your boosters and have to buy more what a huge money drainer ripp off and when ever I complained about it they just say that it's not their fault don't waste your time and money on this game is just trying to rip you off especially once you get to master2 the timers freeze and the computer opponents always win and takes your legendary boosters that's why I uninstalled it
