Not sure how its actually being done but there is a lot of cheating going on. Lots of questionable wi-if disconnectivity moments and then suddenly the opponent is the winner.
When I first downloaded and played CR I was excited. It started out as a fun game and immediately preferred this to CoC. In fact, after about 3 weeks of playing I still find it somewhat fun. However, the part I do not find fun is seeing the blatant imbalance in battles between troops of the same type. Watching my level 2 dragon being taken out quickly by a level 1 dragon when they were deployed within microseconds of each other is ridiculous. I cry when I see my level 7 knight being destroyed by an opponents level 5 knight. Methinks there is a problem in AI programming at the Supercell Game Dev Sweatshop. Its games like this that reminds me I should turn off the iPad and go play a real game. And the cards in chests never are the ones you need for your current battle stack. Deleted game after a year that I can never get back.
