If you’re having connection problems while playing please do the following: 

1.Make sure you’re connected to a network and that your connection is stable. Sometimes networks get overloaded that leads to a bad Internet access. 
2.If you’re using mobile internet, try to switch to Wi-Fi. We recommend using Wi-Fi or 3G/4G since they offer a better connection. 
3.You can also try to restart your device and reload the game.
