So, this app recently has had to come under new management and not for the better. The solo challenges are exceedingly difficult and purposely so, so that you feel pressured to BUY coins to assist you. Also, the Lightning Round, which was so much fun, was no where to be found just last night. It's obvious that it's not the same game. 😒 I Uninstalled it. I just don't have the money they are looking for to continue with this BS.
