I voted 5-10. But was probably 0-5. I remember my first babysitter had a Mini Cycle machine in their basement. I don't actually remember playing it, but do remember saying "I wan't to play pinball (again)."
I was 3 when I went to that sitter.
I remember dad taking me to the arcade in the 6-7 age range and seeing a Bally Playboy. At that time I had no idea what the theme was about.
