No wonder you are confused, since banking settings are different in old flash and new unity client.

Slightly out of date this wiki page.
Anyway, if you want the fancier boot options you need to create the game in flash. (So on the website, aka here, go to your name and switch to flash. Unless you have flash thing on your phone, you would need a pc to do it.)
