wow, disagree on this. Got Vacation jackpot in the first dozen games I played on it. Heck, recently I got it on my first ball.

as far as other williams/bally games .. .

agree with others WCS94 is easy to get and a fun wizard mode given the manual plunger.

STTNG, pretty easy to get, but the challenge is getting there with at least 4 artifacts, although I don't really consider it "beating the machine" unless I have 8, which means you completed most of the missions.

Getting LITZ on TZ is not super hard if you work/complete the upper playfield, but it doest have a great sense of satisfaction when you do it.

Completing all four 'objectives' in i500 is doable (no real 'wizard mode'), if you really focus on the passing and get the bonus passes in one of the modes, that is by far the hardest of the four.

getting across the country in RS to the wizard mode, also not hard, completing the entire country, much, much harder.

I've never tried to do that on SS, so next time I play . . .

I think this is true of many wizard modes, you need to be really focusing and strategizing on getting there vs just getting a high score or just playing the game and seeing if you get there. In WH20 for example, you need to be conscious of not locking balls early on, since once you start MB twice, that third time is an absolute bitch (but very rewarding when you actually do it). Many of the games on this list have that type of a requirement as far as the strategy of play.
