Quoted from silver_spinner:elektra.
there is actually a purpose to it.
hit 3 targets on left lights left rollover, hit 3 targets on right lights the other rollover. hit all 6 of the targets also lights the 2x bonus target, then hit that for 2x of course.. the bonus is huge playing the mini pf if you do it right, it has its own bonus different from main pf bonus.
This is so true - from my point of view the only mini playfield with a proof of concept that they could be fun!
Honorably mentions for TZ and Shadow, since they are really "innovative".
