Good points from the plinko section on the far right, but the return to the right inlane can be dangerous. Be ready to nudge.
Don't let the ball roll up the right flipper or it will drain.
Hit A-B-C-D rollovers to light drop targets and increase saucer value.
Complete drops to light bullseye targets for 5K each.
Raise the flipper and let the ball hop up to pass it low and controlled. Be careful about adding too much lateral starting from a cradle.
The lit inlanes are some of the biggest score (5000) throughout the game, but hitting the standups and drop targets is lower risk.
