Ok tried to figure this out on my own but failed. I'm confused on the Yumiko Easter Egg. I'm playing Hotshots w/Amy. I get to the quarters game as MC and save the game. I play quarters win some/lose some, reload save, rinse and repeat. So I've now won (conservatively) quarters at least 50 times (and gotten pretty good I must say). But each time it kicks to Amy to drink a shot or undress. I've picked both, looked around for the egg but no go.
So my questions are:
1) Does WINNING quarters trigger the Easter Egg (and thus I should just keep playing until it shows up)?
or
2) Am I missing a hidden object/Easter Egg during or after the quarters game?
I'm doing something wrong or that 10% is bollocks!
