"To be fair, pinball really did involve a lot less skill in the early years of the game—largely because the flipper wasn't invented until 1947... up until then, players would bump and tilt the machines in order to sway the ball's gravity."
I never knew that. It was a grown up version of the labyrinth toy.
Now that arcades are just about dead in America, the only time you see a real pinball machine is in a collector's gallery or on TV.
