Rolling over top lanes lights the corresponding drain (outlanes and centre) for 500 points e.g. B lights inner left outlane. The light will briefly go out when you hit the standup target bank, so rapid drains off them might not score 500.
Hitting the standup target bank will light corresponding pop (10 pts when lit) or rear standup target (100 pts when lit) depending on whether bank is in left or right position.
Rolling over all five top lanes lights special at the “C” lane. These hold over from ball to ball.
Hitting all eight standup bank targets (each target in both left and right position) will light special at one of the fan targets. Special will change sides with certain switch hits.
My best games have come from quickly lighting the rear standups for 100 pts each, then continually sending the ball up there to hit them repeatedly off the pops. Lighting all drains for 500 pts also makes a big difference to score.
