review Games are fun to play with lots of challenges. But often when you win a bunch of coins the game freezes, forcing you to close it without collecting your coins. As you must buy coins for real money with your reward only virtual by winning tournaments or more play coins, a frozen game is very frustrating. The bug needs attention as one reviewer noted above. I have a new iPhone so the problem is not mine. In the last three days different slots have frozen so I will not play until it is fixed. I lost too many winnings!
