Garling might also be interested in showing weather or not the casinos who offer odds of winning such as 90% payout actually pay out at those odds
I tried looking into stuff like that. Several creators were willing to share some details of the calculations, but in the end you still need to trust them. If you find a very suspicious game, I may look into it... but usually it just requires too much "charity" participation from the creators. If the game is cheap though, I can always buy it and try it out.

No matter if you win or lose in the short term, in the long term, the casinos will always win! How do you think they can afford to build what they build in Las Vegas?
While I agree with your sentiment ("play for fun, not for money"

, I don't really agree with your statements here. In fact, it is thoughts like that ("in the long term casinos will always win"

that has probably led to several "scam" casinos here.
The fact is, you need a fairly serious bankroll to stay afloat as a casino. My friend has ran into a couple in SL that don't realize this. (I'm a low stakes man and haven't ran into it yet myself.) For example, video poker is close to 100% payout. For the customer playing many hands, the risk is nice and steady ... risk XXX per bet.
However, for the casino, the payouts are varied and come in large spikes. If you have more money than the casino, and the casino is only stocking like 20x's your bet ... it is not unreasonable for you to be able to empty the casino's bank. My friend actually used this to "extract revenge" on the casino that didn't pay out, and drained their account twice. I still don't think they've learned their lesson, and refuse to pay off big winnings. (BTW, this was Misty's Casino ... I'd suggest never gambling there. I considered it shocking because the place was
large and appeared well designed / care given to layout, with plenty of campers to feed money into the system. I tacitly used such indications to decide which places would be more trustworthy, using the notion that "they couldn't get big if they didn't play it straight, right?". Apparrently not. Discussions over this, and how casinos could be "successful" with such horrid policies, led to more indepth discussions of casino regulation in Sl ... and in a sense, led to this project. (Although, I was asking for verification of odds/fairness from casino owners and script writers much before that. But the more frequent discussion spurred by that event definitely helped solidify things.)
As with all business, there is a kind of tradeoff ... the better payout, the more popular the machines ... but the more risk you take as well. Apparrently, some are too conservative on calculating the bank roll required. (Or for the really pessimistic, those casinos purposely set the bank low so they never have to pay out on large hands. One can never prove intentions though, so I'll try to ignore that nagging thought.)
On a side, note, several real life casino games do pay out more than 100%. One is blackjack if you card count, but they will boot you. The only others I know of is certain video poker machines. I don't really understand the economics behind it. Maybe they are just banking on "people are idiots" (probably a good bet) and will not make the correct choices every single time over the thousands of bets required to actually avarage ahead? Who knows.
Or maybe it is just to bring people into the casino? Is so, there are SL equivalents - For example the "higher/lower guess a number" games that pay you for playing. Or even worse, the annoying camping chairs (but of course, that has a whole different economic push behind it).
