The two closest games I've had were 6/8 gems, once including the Mega Jackpot. I may never reach the true wizard mode but honestly I don't dislike that fact. The game has tons that's worth doing besides the true wizard mode, it always gives me something to try for, and I don't think every single wizard mode out there needs to be a handout or even realistic. I think pinball benefits from having a few SOTRs or Super Duper Mega Extreme wizard modes out there.
There is, however, a video of IE Pinball getting to SOTR on 3 ball factory settings. The end of the video though is... well, I've never seen the actual mode.
