- sign up to gree.net
- dig up a japanese VPN (FlyVPN was suggested.)
- install "cTouch r2" for chrome, set the UA to iPad (iOS 6.1)
- open pf.gree.net/58737
- complete the tutorial
Once done the VPN is no longer needed and you can play the game using this address: http://app.ip.bn765.com/app/index.php
Might or might not work. Don't really remember what I did to make the game work.
