Definitely just an ad filled scratcher app. I sat and watched and screen recorded the trophy game ending, I was clearly leading by 500 trophies and the app proceeded to crash and black screen so I restarted the app and it said I finished 18th. If you aren't going to honor your trophy mini games why have them? Also, if that's not how the mini game works at least make that clear. Currently at $9 just got there today so, according to other reviews, I shouldn't expect to get any more winnings.
