I'm gonna be straight up with you.... do not and I repeat DO NOT get this app it is a HUGE waste of time. You are better off asking your parents or any other person. This app I have been playing For WEEKS and still have not gotten my reward the longer you play the harder it gets and the more time you'll be there! How you go from your 2 digits to 0.001!?!? Explain? This game is so difficult and you don't even know if you will get the reward!!!! So like I said DO NOT get this time wasting game!!!
