that is... a ramp straight from the playfield to the top of the cabinet.
A "test your strength" pin. I like it!
I could see many of the old table/redemption game ideas fitting into pinball:
Slots - fill reels with balls to increase odds of 'winning' multiball
Roll-down bingo - Apollo 13-style multiball where you fill slots around playfield for other goals
Grip test - make plunge strength your grip strength
Crane game - use crane on balls to fill locks for multiball, etc.
Love tester - ??? Ok, maybe nothing here...
