ok some basic stuff about the mobile game:

1. only available on android so far via a chinese app store

2. only 3 servers in China's timezone and all are full at the moment

3. not related to the browser version (in the sense that the ninjas have some different skillsets and designs and animations. it will not be a mobile copy of the current browser version) even though currently both games are developed by tencent and bandai i think

we are in general a pretty long way away from getting a global version, i would imagine. but if you want to play there u can download the app and get ready for the next server release i guess.
