I graduated from level 15 and it went up to level 16 without offering the one time deal purchase. The same thing happened once before in one of my lower levels. Also, tap joy is rubbish and doesn’t reply to emails about issues getting hard cash. Also, my matches keep ending and saying opponent wins when I’m in the lead and the match isn’t over yet. There are a lot of glitches in this game. Pretty disappointing unless youngish them.
