Seemed fun, turns out it's not. Spend 1050 coins to play a level, win it with one or two stars and only get a small fraction back!!? If you win a level at least give enough coins to progress.... Have found a much more satisfying app where I can play for longer than two minutes at a time. ETA - I was also pretty annoyed that I paid the $7.49 to unlock the extra chests only to lose it in the next level of stages and I couldn't even claim the previous ones I had passed?
