BIG VALLEY pinball machine from Bally (05/1970) in Gameplay

Greetings from germany. It's a really great EM multiball pinball machine, this Big Valley. Produced in 1970 it was certainly a real hit at the time. I myself never got to know this pinball on location because it was a long way before “my time” playing pinball machines. During the game, you absolutely have to manage to "free" the trapped balls (sometimes one - sometimes two) and thereby score big points. Illuminating the pop bumpers is also essential, because then the score just rustles. This pinball machine is really fun when 4 players play against each other and one steals the balls from the other. A really crazy idea that Bally realized. Check it out if you ever meet this iconic game somewhere!
