the technology is there for them to cheat I'd bet my farm on it. It's why sometimes its fun to make up your own Pick 3 game.
Years ago, while living in Jersey, and tending Bar, I ran my own pick 3 game among about twenty people, prize starts out with $200 and builds each week if no one won. It could of been bigger if I let it, but it was getting hairy to manage with just twenty people and the increasing pot that was building.
The buy in was $10 and you got 10 combos in play for the Eve game everyday until someone won, but the combos weren't what people choose--- they were combos made by they own birth star measurements---for instance, born 9/18 puts the Sun at 175 of the celestial coordinate system, so 175 was one of my numbers. Continue that, for the Moon, Mercury, Venus, etc till everyone got their 10 planets at birth measured and the combos in play for the games ahead.
Everyone in got a piece of paper with their number/star combs, and everyone else's combo/star numbers. So they could see if their number was draw, BOX OR STRAIGHT, they knew who they would share the prize with. We used the New Jersey pick 3 as our winning combo to check our papers, but every week if no one won, everybody puts in another $10 bucks and the pot increased and grew nicely.
You see, star measurements only go up 360 degrees, so lots of times our prize money was a HOT waiting building up nicely because 859 was drawn, or 746 for instance. As no star measurements includes those numbers. So the pot grew quickly. What was nice about it, is that the growing pot was always going to go to one of us in the small group.
More and more people wanted in on it, but my limit was Twenty people. If someone dropped out, I let someone else take their place. It was a lot of fun, and exciting when the prize built up. Some folks had the same numbers and would split the prize, but most often someone won it by themselves. Sadly, I don't know enough people here in Ohio, to do it again or who like to gamble who would participate, so its just stands now as a good memory. I didn't even track the draws back then, I just liked to gamble and wanted to keep the money among a consistent few. It worked. Everybody loved it. And I sure do miss it.
After watching the crap they pulled over the last few months---I can't help but to think back to the days when a bunch of us made the game fair.
