No too awful long ago casinos provided slots for high rollers wives to have something to do while thier husbands were at the tables. That was the thinking back then.
The visionaries in the business kept saying there was a generation coming up that were video game players and guess what they're going to plau when they're old enought to gamble.
One night we had an old time boxman go on break with us (the old timers had great stories) and he spotted three nckel slots that they had tucked away by a bar. Old time "reel" machines, not computerized. These slots had three wheels and nine "stops", like gears, so the odds of a jackpt (which were way smaller then) were 9 X 9 X 9. But you didn't have to win the max prize to make money.
Well when he saw this machine he stopped and said (to the machine), "Hello old friend", thenm he told us, "I made a down payment on a house playing these and it's how I used to pay my mortgage. I didn;t know these downtoen joints still had any."
Then he explained "timing the machine", that is pulling the handle at just the right time. Kind of like a real good safecracker might work.
A couple of guys were skeptics but you could play in this casino (just not table games) on your breaks and this guy was winning $20 - $25 a break in nickels.
Just another reason everything went electronic.
