John, the only live gaming I ever saw in the 60s and 70s in the Bingo club was a single 21 game.
There was a large room for bingo and there were a few slots. There was a large bar room in the
back where a lot of the dealers would sneak a drink on their break. There wasn't much room for anything else. Since they had 12 1/2 chips, I think those purple chips were quarters. You could
probably make 25 cent bets.
