I bet every Shinhwa Changjos are familiar with this game. I very recently tried this game and it is quite exciting. Well, maybe because I know Shinhwa play this too. Otherwise this game is good for killing time or when you are waiting for someone/something. I found it as an entertaining companion when I wait for my lecturer. For android you can find it here. But make sure you have Kakao account too.https://play.google.com/store/apps/details?id=com.sundaytoz.mobile.anipang.google.service The minus of this game is it needs constant internet connection.
