Hit flashing blue stand ups to collect Electra points. At least 6 enables valuable lower playfield time when you drain.
The Elektra units are worth the most (blue stand up targets on left side, hit flashing one to light the rest once you get a few lit really easy to stack). Upper three green targets also give 2 units per target one time only
For multi ball, hit red stand up targets 1,2, and 3 a few times to light lock. After ball is locked repeat to release ball
