The ball save is only if you don’t hit any bumpers or roll-overs after plunging. The skill shot should still be blinking.
One strategy is to light all bumpers then hit the scoop, next light 3 bumpers only then repeatedly hit the scoop to rack up big points.
The skill shot always grants you the right-most top lane remaining.
You can hit the second lane from the right from the right flipper if you shoot if straight between the melon bumpers.
The center of the bullseyes and the saucer score 200 when lit, 50 when unlit. The scoop scores an additional 10 points for each lit bumper.
From the plunger, the single toplane scores a skillshot which awards 200 and spots one of the toplanes.
Each of the four left toplanes lights one pop bumper and one rollover for 10 points (instead of 1).
