DONT TILT! Any decent ball is likely to have a large bonus.
Concentrate on increasing bonus multiplier above other goals. Pop bumper hits light or unlight lower drops to increase from 2X to 5X.
Shoot any standing star(yellow) drop target when lit to increase bonus multiplier.
Extra ball targets lit by completing ABCD or one set of the upper drops.
Although you can earn 3 extra balls (ABCD, White Drops, Red Drops), Genie only lets you earn one per ball, so dont be greedy.
Attack upper left playfield drop targets to build up bonus value. Shoot spinner when lit to build bonus value.
Bonus collect saucer lights after 20,000 bonus has been reached.
Basically everything on the game builds bonus, so its all about not tilting and increasing the multiplier
Max bonus is 29,000 at 5x = 145k
bonus multiplier is shots to lower drop target bank when lit.
