Since we can't spend thousands of plays checking the coin-in & coin-out of the banks of machines involved, is it like the Bingo slots where someone else has to lose for you to win or vice-versa? And if nobody but me is playing those banks of machines, I could play for hours on $40 and rack up $40 of session points?

Seems the machines are always scraping by with the minimum hold to me.

To clarify: I still believe that the games in Nevada are genuinely random. But I could be wrong!

And sometimes the lack of randomness isn't deliberate; mistakes happen. From the August 2011 issue of Harper's magazine: "In 1998, the Arizona lottery began using a computerized system for the Pick 3 game. A Chandler woman named Ruth Wennerlund always picked the same three digits, 9-0-7 (her son was born on September 7). After a month under the new system, she noticed something peculiar: the number 9 had never been drawn. She called the Arizona Lottery to complain. They told her that she was merely unlucky. A few days later the Lottery announced that a glitch in their random-number generator had prevented any 9s from being chosen. The thousands of people who had played the tickets with the number 9 were offered refunds-- but only if they had kept their losing ticket stubs."

What's nuts is...even after 32 draws, there was still a 1 in 24,701 chance that 9 would never have been drawn in a fair game, still decently within the realm of possibility.

Although I've been writing code for a good long time I must confess I'm new to the details of gaming side of all this.

Any help is always appreciated.

Nevada has a "live game correlation" law. So the patent issued would not be a legal game in Nevada. But there are some US jurisdictions where "Class II" or "virtual pulltabs" are the only legal options for gambling games. Hence that patent for a keno game that functions this way.

Here is the Nevada "live game correlation" law:

14.040 2 (b)

(b) For gaming devices that are representative of live gambling games, the mathematical

probability of a symbol or other element appearing in a game outcome must be equal to the

mathematical probability of that symbol or element occurring in the live gambling game. For other

gaming devices, the mathematical probability of a symbol appearing in a position in any game

outcome must be constant.

It's in the bottom third of page 171 in this pdf:

So a machine in Nevada functioning as described by the patent you linked would be against Nevada law, and it's highly unlikely that any reputable manufacturer such as IGT would send a machine that could function illegally to a casino. If they did, I would be 99.54% sure (to use a pun from the Wizard) it would be an accident.

And also from the patent:Quote:IGT patentRegulatory bodies in certain jurisdictions do not permit the use of probability-based gaming terminals, in part for these reasons. These regulatory bodies permit the use of wagering gaming terminals which are guaranteed to provide certain or definite awards, so that, for example, a certain number of wins is guaranteed and the overall amount paid back to players is guaranteed.

It's unfortunate they didn't clearly label the "certain jurisdictions" here. The two largest I believe are New York state-run racinos and Washington state casinos. Nevada is definitely NOT one of these places. IGT does serve all over the country though, including New York and Washington.

what i am claiming is that tringlomane quoted a part of the patent

and that his interpretation of the quote is wrong

when it says "Regulatory bodies in certain jurisdictions do not permit the use of probability-based gaming terminals, in part for these reasons."

and then goes on to say "These regulatory bodies permit the use of wagering gaming terminals which are guaranteed to provide certain or definite awards, so that, for example, a certain number of wins is guaranteed and the overall amount paid back to players is guaranteed."

well the interpretation is backwards... the second quote ... "These regulatory bodies permit the use of wagering gaming terminals which are guaranteed to provide certain or definite awards, so that, for example, a certain number of wins is guaranteed and the overall amount paid back to players is guaranteed."

is talking about PULL TAB/BINGO because how can it be talking about a fully random machine... they cant garentee a paypack if its fully random

and the first quote is talking about the rest or "fully random" slot machines

1) The machine sucks in coins and has a low payback percentage

2) The machine plays normally and the payback percentage is normal

3) The machine is spitting out money to a lucky player and the payback percentage exceeds 100% for a brief time (how brief? one pull?).

In the short term, all this is possible without tampering with the machine. In the longer run, say 10K spins or more, you'll get closer to the setting on the machine's payback percentage.

i cant prove or disprove those statements

i am mainly focused on the sub conversation that was produced as a result of this original conversation

im trying to figure out what probability based gaming is

i know its not a centrally determined game thats for sure
