If you really want to go nuts, there's another setting that tells the game to carry over your Millions+ value to subsequent multiballs!
Say you have 3 multiballs and hit the trap door three times each. Instead of 2,3,4 million; 2,3,4; 2,3,4 you'd get 2,3,4;5,6,7;8,9,10 million! 27 million vs 54 million!
Once you have it up there, it really gives you the impetus go grind through to o n e. m o r e. m u l t i b a l l.
Now indulge me while I tell you how I thought I had lost my mind 10 minutes ago:
Like a good Pinsider, I wanted to tell you which setting it was, exactly what it's called. So I download a pdf of the manual, and damn! I don't see it! Was I imagining this setting? Did I dream it?
Wait a minute, this pdf just so happens to be missing a whole page, right in the middle of the list of Feature Settings! Page "1-15" which lists features A2 10 through A2 17! Just my luck!
So I get off my lazy ass and head to the basement to see it in my own hard copy of the manual. Ah, there that page is... huh? No such feature on that page either! Now I'm really getting concerned.
Hesitantly, I go and turn on my game, and enter the menu... Features... Whew! A2.20 MIL.+ CARRYOVER
Of course, newer revisions often have features that didn't make it into the manuals. As in this case, I have L-9 in the game. I couldn't say whether any earlier revs have that setting.
I wasn't really worried. But it was a good example of how my life goes, nothing is ever as simple as it ought to be.
