Not sure if it just became really scammy now (January/February) or now that I've been playing for awhile but suddenly I'm downloading games that I've never played through the app and it tells me I'll receive, say, a 4x credit reward speed, which was actually doubled to 8 and suddenly while I'm playing, that changes to .5× doubled to 1. Or 2.5× down to .5x . Last two games in a row, completely different, on different days, WHILE I'm playing. Seems pretty sketchy to me.
