It was fun... Until I hit level 2700. Up to this point, I did not buy any coins - merely relying on the free 30 min extra birds, or coins given from leveling up, or completing team events. The extra 3 moves from watching ads sometimes saved my bacon too. But when I reached 2700, even with all three birds won from winning consecutively AND free 30 min birds or whatever, I can still fail a level, and a normal level at that. This is getting very frustrating to play.
