There is a small rollover by the spinner turnaround. If you hit it the left inlane lights for 9000.
Every fourth spin of the spinner advances bonus, as do the top saucer, the outlanes and various targets.
Complete the right drop target bank to score 6,000 points plus bonus multipliers (2X, 3X, then 5x) which lasts for the rest of the ball.
The left lane collects multiplied bonus. After doing so, the base bonus resets, but the bonus multiplier doesn't.
