This game USE TO BE great. It's just gets worse the longer you play it. I've spent real money on this game and I have a bunch of time playing it. I still haven't made much progress and certain bowling balls WILL NOT unlock at all for me no matter what I do. Now I'm stuck on a Alley where no matter what I do there is ALWAYS one pin left standing. It's almost like a glitch. I can no longer make a strike to save my life. I'm about ready to delete it.
