I attempted to purchase in app games and it just froze after the purchase. I finally decided to exit the game and check to see if my iTunes account was charged. It was not so I thought I would try it again. The same result occurred however when I checked my iTunes balance I had been charged twice for the each attempt but yet had no gems inside the game. This is obvisoulsy a flaw. I called Apple support and they refuned my money although they said next time I would have to contact Glu Games directly. It appears to me that the game is either not well designed or Glu is not a reputable company. Thank god Apple is and they honoured a refund. Very disappointed as I do enjoy playing the game.
