If you are interested in playing 10 minutes a day, this is a really fun game. Fully charged, you get 75 energy. Each game requires 10 energy and your reward for finishing a puzzle is 1 energy, so at most you get to play 8 puzzles before you are out of energy. You can buy more with game cash, but that too is rewarded 1-3 at a time, so it doesnt take long before you are spending your own cash to continue playing.
I had been playing Pearls Peril by the same developer, until it crashed. I downloaded this expecting something similar, but am very disappointed!! I can play Pearls Peril for an hour without buying anything with either form of cash. Will be going back to that game!!
