Hit the captive ball until the yellow targets are lit. Hit yellow targets for points, bonus, and bonus X.
Hitting the saucer when not lit for Collect Bonus will add bonus based on the current position of the captive ball. For example if the ball is at position 3, you will get +3 bonus. If this maxes your bonus, you will instantly collect it.
The collect bonus hole lights when bonus is maxed.
