Drilled Used Casino Dice

Need some expertise
My wife and I have played poker with a couple of other couples every 6-8 weeks for over 10 years

At the end of each night, the host couple take a pair of dice and roll. If snake eyes or box cars come up, that couple wins a progressive pot that we all add to each time we play

In 10+ years, my wife and I are the only couple that has ever won(4-5 times now over that time period)

Because of our past luck, whenever we host, we joke that we need our 'special dice'

For our most recent win, we used a pair of drilled out used casino dice that another of the couples gave us. Both dice were drilled out thru the 1 and the 6

When we rolled 2-6's, there was not exactly a celebration for our good fortune....we, have never intentionally, done anything that would increase our odds but we must be VERY lucky to hits 4 or 5 times in our 25-30 chances over the past 10-11 years...Yes?)

-My Question-
By using these drilled out dice for our last win, did we, in any way, increase our chances?

It seems to me that the dice are actually weighted against our favor as the heavier sides are all BUT the 1 and 6

Any thoughts or expertise on the matter would be appreciated

Casinos want to identify their dice and their retired dice. Dice can be retired for chipped edges but weighted dice can alter randomness.

better a cheapie pair of dice that is roughly fair than a pair that has been retired.

Totally agree, drilling no doubt effected the roll but seems(after we gave it some thought) that the effect would have been to actually decrease the odds of rolling 1s and 6s....?

Did the fact that these particular dice were drilled out down thru the 1 and 6, INCREASE our odds?

If so, we are inclined to return our winnings(these are our friends!) and re-roll

Each couple uses different dice? The way to be sure it's fair is to have all use the same dice.

It would have decreased your odds as you said since the 1 and 6 faces are missing material. I have some dice like that, too, and it's usually a substantial amount that's drilled out, so the effect would probably be noticeable over even just a small trial.

I think that if the surface the dice were rolled on wasn't smooth, having a hole on a face would increase the likelihood of it catching on something and staying face down. Even if the surface was smooth, wouldn't the lighter side(s) of each die have a greater likelihood of coming to rest face up when compared to the heavier faces, even if they were opposed?

I think were going to suggest moving forward...

I guess thats my question....

I assumed the heavier sides w/o the holes(2-3-4-5) would be 'weighted' and therefore more likely to end up on the bottom. Meaning the 1 and 6 side would be LESS likely;y to come up

Thanks for the Reply

'Host' couple just grab dice they had/we used that evening(for a couple of other games we play)

I think were going to suggest one set of 'official' dice moving forward...

Thx for the Reply

How are you throwing them?

If you are just doing a drop-roll as if playing Monopoly then I doubt it matters much if at all. Not enough motion of the dice to matter.

OTOH, if they have a full size craps table then it might make a difference as the entire balance of the dice are now off. But over a small trial I doubt it matters.

Actually, the I think the complete sides would cancel each other out, since the most weight at the lowest point on each die would be all four complete faces around the sides. This would leave the lighter sides on the top and bottom.
