It's fun at first but as soon as you get to higher levels it gets frustrating. In order to pass, you need to make lots of power ups and combo of the color power up, or lots of diamonds (have to spend real $) to continue playing after losing all moves. Majority of the levels are less than 15 moves and the tiles needs to be hit 1 up to 5 times. The last few hard, super hard, and challenge levels are next to impossible. Literally spend 1 hour or more on this levels with 1-3 hour life rewards i got.
