This game has the worst algorithm, full of network and connection problems and they don't develop anything they say we've updated but it becomes worse. Actually is not a game it is just an app which relies only on the internet connection, if you have a really good internet connection and even you don't know how to play you'll still win and have a good rating. I've emailed them for years but they're not changing anything.In the end I want to say that deal with your trade but let it not be a scam
