The basic play is building up your bonus. The big points are building up the saucer value and collecting it over and over!
Green drop targets increase the saucer value by 1k each. Completing the green targets lights the extra ball at the “5” stand-up target.
1-2-3-4-5 (targets or rollovers) light the left orbit star rollovers for 1k and upper drop targets for triple bonus advance. Complete 1-2-3-4-5 to light special at outlane.
1-2-3-4-5 don’t reset on an extra ball so the 1 and 4 outlanes can help get the special.
Bonus maxes at 15k
Completing upper drop targets gives 2x bonus.
My strategy
I prioritize the green targets to increase saucer and get the extra ball.
Once green targets are completed, I use the right flipper to shoot for star rollovers to get up to top. Left flipper backhands the upper target bank.
The ultimate goal is to get up top to try to get in saucer for up to 5k per collect. On some machines (including the Pacific Pinball Museum) the saucer eject often hits the pop and goes right back in the saucer. Possible huge points!
