You would get an different new account if you or ready have one.

to add it login to facebook and go to "http://en-gb.facebook.com/apps/application.php?id=93322515645" and just start playing or click there to play

I am working on having somthing showing on players facebook profiles (still working on this mind)

!!!!Have fun!!!!
