Middle top lane lights spinner. Complete top lanes advances bonus X. Saucer scores lit strike value... just get the spinner lit and rip it.
When the center top lane is lit for Strike, roll though the lane to advance Strike Value. Otherwise you need to complete 10 evil rollovers.
Completing ABC lanes (via spinner) advances the bonus up to 5x. After 5x, each completion is a Special worth tons of extra points.
The Strike Value saucer generally has a nice feed; figure out the return and send the ball back up top accordingly.
