View Full Version : Article about the randomness in dice.

Normally I wouldn't post a link to an article here, but I've seen this topic come up several times. Dice aren't all that random because of the holes drilled into their different faces. We all intuited that the missing mass on certain faces affected the outcome of the roll, but this guy actually studied it.

That's pretty cool. Time to start working on my dice-rolling skills!

Gamers have an uncanny ability to influence dice.

Really? Cause, I'd love to figure that out.

Rolled 5 individual d6 1,000 times each. Average result? 2.1. Want's me some dice luck...

I think it's time for a new set of dice.

No, no. That just means his luck is about to change...[/Gambler's Fallacy]

I've never personally purchased anything from the man, but this (http://en.wikipedia.org/wiki/Lou_Zocchi) guy's spiel at GenCon is usually entertaining. He makes a point that his dice always have clean, sharp edges to try to avoid some of the problems that article talks about.

If you roll dice 10,000 times, you will not end up with equal results for each face anyway. That's not how things work. (For one thing, 10,000 / 6 = 1666.666...) However, a variation of 25 (i.e. 1/400th) occurrences between the most and least common results appears entirely insignificant. You're going to get bigger variation by pure chance, more likely than not.
