Re: Wringer type washing machine - yes, mother had one in the basement, the water dumped into a sump.  Then the sump got pumped out of the sump to the septic drain field.  (as a 4-5 years old, I thought that concept facinating.   The one she had used a motorized wringer, but you could only put in a couple of things at a time.  The wringers could put a world of hurt on you if you weren't careful.  I was taught to feed with one hand and have the other near the off switch.
Yes, I learned to wash clothes, iron, make sewing repairs, cook and clean the house.  Mom said it was so I would know how when I grew up.  I think it was just household labor.
Re:  Electric football game.  The 'field vibrated' and the men moved.  Invariably, there was one piece which just moved in a tiny circle.  Occasionally the quarterback would turn around and run in the wrong direction.
We also had a race car game based on the same principle.  (I was 7 or 8 at that time.)  A vacuum formed race track had paths for the cars to follow.  (I think this was 
the one - or at least similar.)  The tracks crossed each other so occasionally there were crashes.  I learned that betting was not always a good thing as it was always anybody's race.  My Dad and I actually kept stats for a while to see if you could determine which car was most likely to win and which track.  (Fun times learning statistics and math in a game format.  Only I didn't realize I was learning.)
Re:  Other games, my kids had hungry hippos.  I had a friend with the Rock 'em Sockem 'em robots.  Never had or played on the mini pool table.
