This game starts out fairly challenging-especially new AB players. HOWEVER as you get more into the game-the challenges start to get IMPOSSIBLE -UNLESS YOU KEEP SPENDING MONEY.IT is structured to keep collecting money to play.I played it for a month and quite well(LT AB player) but there is a place where you hit a wall and connot complete the challenges unless you keep buying and buying coins. MONEY PIT. IT's easy at first but then it becomes impossible to play without paying.DO NOT BOTHER.
