Collect both A and B, double the bonus, collect via the right gate. Repeat
From the right flipper always shoot the left orbit.
From the left flipper:
with low bonus shoot for the upper right advance bonus sling
if bonus is near max and not doubled, shoot for center saucer
if bonus is doubled, then the collect bonus gate in the middle right is the better shot
or you could risk a pass to the right flipper (draingerous)
Plunge for the A lane, lights the safer, upper right sling for advance bonus
The left orbit has a wide entrance and is the way to get back to the top
Collect both A and B via top lanes or inlanes and then double base bonus from hitting the lit center lane or make the center saucer (draingerous).
At any time bonus can be collected by shooting through the gate in the middle right of the playfield.
This resets bonus, turns of double bonus, and you will then need to recollect A and B
Making the center saucer will also increase the saucer level which may award an extra ball or special. Other than enabling double bonus this is not worth intentionally shooting.
