I would give it negative stars if I could!! Dont go by the rating, they pay for it!! It's definitely one of those money sucking games making you think that the play will be better if you get upgraded players but it's not, you can tell the algorithm is against you, at times you make the right moves and it's fun and competitive, other times the other player, (probably a bot) is all over you and you can't do nothing. It's a uninstall for me!!
