Ignore the 1 star ratings, people saying how you need to spend money etc... I'm at the current maximum level, and not Once have I spent any money on this game. For a free game it's brilliant,, very enjoyable, frustrating at times with the tricky levels, but that's part of the fun! Only one criticism.... You can't earn stars when in the tournament of champions, so I was unable to finish a redevelopment, which wasn't my fault
