Quoted from Pinmeister:Maybe the next Stern should be "Unfinished Code". Every time you complete a mode, additional code is unlocked. The beauty of it is that it could be upgraded pretty much forever, and yet never be done. It would be the ultimate Stern.
No. The way it really works, is the farther you get, the more the code is unfinished until you get to that great "Wizard Mode Multiball" placeholder multiball.
