Both banks of drops are linked in multiball. Focus on upper playfield to quickly raise the drop value and collect decent points in mball.
Top lanes and ramp adds "PIN BALL" letters (i.e., bonus) in center of playfield.
Spelling "PIN BALL" lights special. When set to points, Special is worth 500k (big points; you can look at it as a 'Super Jackpot').
Completing top lanes, or 1 - 7 yellow targets, builds playfield bonus X. This value multiplies switch values in multiball.
Heat bumper is not worth much on its own, but can quickly build the multi-bonus in multiball when your playfield multiplier is high.
Complete both banks of drops to raise the base drop completion value; maxes at 50k a set. Extra Ball lights after, which is worth 200k.
Three shots to start multiball--two locks on the upper playfield, then the ramp shot to start the multiball.
"Hot Shot" ramp is risky. If on right flipper, post transfer to left, then hit the ramp for 50k or shoot the right orbit to feed upper PF.
