On the last ball, once you lite 2X Bonus, it will alternate between 2X and 5X Bonus based on switch hits. Consider draining if you have 5X.
Spinner is lit when bonus = 2K, 8K, 14K and 20K. When lit, spinner is worth 1K a spin instead of 100pts.
Run up your bonus (double is even better!) and collect at upper right saucer.
Double bonus can be lit by completing upper drops 2X or collecting 3 arrows. Arrows are collected @ upper right lane & center right standup.
