My son played this every day and really enjoyed it. We even bought some in-app purchases. Then one day last week the program stopped loading. It finally reloaded today and all of his levels, coins, gems, tickets and Smurfs had gone back to ZERO! He spent the evening crying and screaming about it. I am not sure he should play it any more. He wants me to type how many of each thing he had: level 80, 82 tickets, 200,000 coins, 135 gems, 5 sends, and the following Smurfs: Smurfette, doctor, poet, hefty, dopey, graduate, farmer, handy, wild, rainy day, cook, snappy, chilly, sasette, reporter, papa, painter, lumberjack and he was on the process of getting thief.
