Concentrate on the drop targets and getting the ball to the top lanes. Hitting the 1,2,3 targets lights EB at the far right rollover lane.
At 20,000 bonus, Collect Bonus is available. Park the ball in a kicker lane (or saucer?) to reset your bonus.
The lanes up top are your bonus x, and will cycle between 2-5x. Collecting a higher value lane advances bonus X to that value.
The slings on this game are passive, so watch out for unexpected bounces off of them!
Hitting the 1-2-3 standup targets lights an extra ball at the right rollover, and also lights the spinner for 1K/spin.
