I think there is a trick for building the vortex multiplier quickly. When in multiball, if you get one of the balls into the plunger lane, and then shoot the other ball up the left ramp, you can build the vortex multiplier to 10x by pushing the ball in the plunger lane off the plunger lane switch a bunch of times while the ball that was shot up the left ramp is in transit.
Quoted from noahpdavis:Highest scoring opportunities are building the vortex shot up to 10x (besides a crazy high solar value). I believe if you collect it during MB it's 100k x 10x x 2x for for a possible 2M point shot. The planets are worth 20k a piece in bonus, so while a cool idea/feature to progress through . . . somewhat worthless points wise.
