Shoot the lit saucer, if it is on the opposite side from the flipper, otherwise shoot the drop targets. Use the upper flippers to shoot drop bank, ball can usually be cradled there.
Make the lit saucer (slightly hidden behind the large bank of drop targets), often using the opposite top lane and bouncing over the pin into the saucer you want.
Top Lanes
The center lane always scores 500 points
Of the other two lanes, one will be lit for 500 points, the unlit lane is worth 50
The most important thing here is to use the lanes to get into a lit saucer
Saucer
Land in a lit saucer for 3K points and it increases drops targets bonus value to 1K
An unlit saucer scores 300
Drop Targets
Drop targets score 50 points and are worth 100 bonus points at the end of the ball
Making a lit saucer during the ball will increase the bonus per target to 1000
Completing the entire bank awards the current bonus (either 1K or 10K) resets the bank, increases the value of all targets to 500, and awards an extra ball or special
Collecting bonus clears out the base bonus, so future drop hits score those 500 points each
