Fun game play but this is clearly designed to get you to make a lot of in-app purchases. Some of the puzzles are extremely difficult and rely on a great deal of luck. However, after a few attempts the game cuts you off and tries to sell you more lives. You can wait a pre-determined length of time instead, but its pretty frustrating to be on a roll and have to either stop and wait or pay to play this ostensibly free game.
