Lou_Para, yes, that's what I was looking for, thank you. I'm particularly interested in when the games were popular in the 1940s, when stay-at-home moms were betting 5¢ to play. I'm aware that the winning numbers were hidden in plain sight, for instance in the stock market pages of the newspaper where the last three digits or the middle three digits of a particular stock was the winning number, and that this was done to ensure an honest game. But who picked the method? The guy running the whole game, I assume? How would a lowly runner move up through the ranks to a higher position?
