Bias in certain dice

I found this paper interesting. Both the historical test by Weldon (that I wasn’t aware of) and the new test by the author. I especially found it interesting how the source of bias was different in the two tests.

I am a bit reluctant to post the link for fear of starting a flare up over biased dice in casinos, but ultimately decided to risk it. Note that the paper does not test casino dice, rather the cheap white dice (I’m imagining the ones that come with most board games). I wonder whether the author would be interested in re-running the experiment on casino dice.

Have you ever heard of the company H.C. Evans?

there is a popular "Rigged Roulette Wheel" restoration video - https://www.youtube.com/watch?v=TavAtAr9gIU - although the video does not mention the name of the manufacturer, it is for sure an H.C. Evans.

Now to the point.

I have an older catalog which clearly shows that they (H.C. Evans) sold weighted dice, which were a countermeasure against high rollers. They sold 2 pairs of dice, one fair and two lobsided. They even produced dice that could be manipulated by magnets, as well as weighted dice which could be made fair by tapping them to normal.

This company existed before most of us and if they had that tech back then think of what they have now?

Of course such things were made and sold.

When Vegas started up, those 'eyes in the sky' were people with binoculars who knew what to look for because they themselves had been crossroaders and dice cheats. Who else do you think Benny Binion would hire to keep things honest?

You can look at old catalogs and see binoculars/cameras that would let a man look out over the ocean but actually focus on the bathing beauties to his side. There were cane swords. There were shoes with fake compartments. There were a great many variants on standard hip flasks that could be used to liven up the punch bowl a bit. There were special devices that ladies could use regarding rings and potions.

Try using crook dice now though. Magnets? I actually witnessed a suit doing a compass walk when a wheel chair was wheeled up to a craps table. Pit bosses still keep a cheap compass in the craps pit just for that purpose.

I'm one of the very few players who generally refuse to pick up an errant die. Its not just that I keep my eyes on my chips, its that I do not want to be suspected of having been involved in introducing some shaved or weighted die into the game. No longer are pit bosses as forgiving as Benny Binion was when a cross roader threw his own two dice but one of the house dice also flew out of his hand: "Go ahead and shoot. Your point is 15."

I'm certain they exist and are used in back door casinos but real casinos with odds on their side have no reason to risk the bad publicity and licensing problems that would emerge if they did (and got caught) doing such a thing.

They might become a fraction worn from wear and tear if they were used long enough but, like playing cards, they get pulled and replaced long before that can happen.

LOL, exactly what I was afraid might happen to this thread.

the question is, does anyone or has anyone ever asked you to confirm if a monopoly or yahtzee dice are biased before you played?

I’ve played poker dice for decent cash and I know some people that play Yahtzee for $. Here’s a question back at you, are backgammon dice more like monopoly dice or casino dice?

ETA: I would be really interested in seeing the study performed on casino dice as I mentioned in the OP. It’s just that this particular study wasn’t done on that.

okay i want to know that too and i dont even play craps

I came across this video touring the high tech equipment at the National Institute of standards and technology (NIST). If they can do microscopic scans of the bullets that killed Kennedy, it would be simple to determine if a cube is fair.

NIST

One thing I didn't know was that the National Archive also has a bullet that was used in an attempted assassination of an army officer prior to the Kennedy assassination that appears to have been fired by the same gun.

If you go get a Yatzeee die, the Archives people will be happy to roll you for possession of that bullet.
