Game is really good, just a few bugs, the one is when the game crashes then your entry fee for races is sometimes not refunded, and when you go from tier 5 to tier 6. It skips tier 6 and puts you in tier 7, which is difficult as you behind on upgrades. Then downloaded the game and just crashes, really is good, but the game keeps crashing, and race starts hit says the game must restart, game is good but annoying, until it's fixed not worth the while.
