Alright, honestly speaking I can't get access to the website as well. However after I tried with VPN I can get access into it and successfully downloaded the app. Apparently I have to rely on VPN to play it.
Today i got an in app update from yareel and since i have installed the update i cant play yareel on my device . The only thing it shows it connection to the game is lost . I have reinstalled the game from yareel.com 3-4 times with and without VPN. But the problem is not fixed yet.
