I've been playing this for a LONG time, over 10 years! I've really enjoyed it. But, early on I remember seeing something that indicated every level could be won with the given number of moves, and without boosters. That might have been the case once, but now it's almost impossible to win most levels without boosters, or the extra moves you can get by watching ads. I'm pretty disappointed by this and am considering quitting. I never have and never will make in game purchases.
