Whenever you collect a wish, choose jewel(s) every time
Light an extra ball by collecting four (adjustable) jewels by finishing modes. Collect it on the right orbit.
Start modes with Genie when princess is lit. Lit yellow inserts often progress modes. Complete a mode for a gem via ramp when Carpet is lit.
Either inlane lights the opposite orbit for a Tiger Loop. Collect six (adjustable) Tiger Loops to light an extra ball on the right orbit.
Anytime you get Lightning Lamp, keep shooting the lamp. The faster and more often it spins, the more points you rack up. (3X Lightning Lamp is even better but only via wishes)
Hold ball on right flipper until Harem insert is lit, then shoot left orbit to spell HAREM for MB. All targets score jackpots.
Spell HAREM during Rocs as last your mode, then wish for the last Gem (not via ramp). This stacks Harem MB w/Genie Battle for unlimited MB.
Get 7 gems via modes or wishes. Shoot genie to start mode. Kill 8 skeletons via yellow inserts to start unlimited multiball. Win MB for 20M.
