Left drop targets in order AND right drop targets in order light two locks for three-ball multiball.
Green X and Orange X multiply each other for a possible 25X. The green multipliers carry over from ball to ball. The orange reset on drain.
Put Ball in top lock first by making right side drops. Avoid lower lock and this will allow locked ball to act as extra ball on a drain.
Left drop targets in order light lock for two-ball multiball
Both flippers have independent lane change
A good starting point is to focus on backhand shots. Backhands from near the top of the flipper will cleanly hit the target bonus.
Finishing the drop targets advances bonus multiplier as well as lighting the locks - they're essential to progression.
