D24 & D30....

[Kilmore]

The D30 is actually useful for rolling the day of the month. The D24? Hmm... hour of the day? Both rather esoteric uses if you ask me, but maybe useful in an astrology campaign.

I painted some black 1s on a couple marbles once.... they're my d1's.

My DM has a d24, a d36, and a real d100 - which awfully closely resembles a golf ball, and is very hard to tell what number you've rolled. I, too, made d3's in wood shop - which kinda freaks me out, now that I've found someone else who did - and the strangest die I've ever seen or heard of was a 2d20 - it had one clear d20 with an opaque d20 suspended inside in some kind of fluid, so that if you shook it up and rolled it you'd get two numbers between 1 and 20. Haven't seen anything like it in years, and I've never been able to remember where the guy who had it told me he got it from.

I love dice. I would collect them if I could afford to, but honestly, I have other things I'd rather spend my money on. Those d5's and d7's are neat, yeah, but paying $5 and $8 for a single die... if it's not made of gold or something, that's just silly. Also, the "2d20" sounds really cool, I'd like to have me one of those.

If you have an interest in dice you should definitely have a look at my dice group the Dice Maniacs' Club aka The Random Fandom. There are over 100 Dice Maniacs and loads of pics and links. There's also a board with news of all the latest dice.

Here's a pic of some d2's and 'gem' d24's on my site. They're from my collection...

And here's of pic of some d5's, d7's and a d9. I don't think the skull d5's, the large orange d5, the d7's or the d9 are true; that is, they don't have an equal chance of rolling each face. The triangular 'gem' d5 is fair, however. It was tested by a professor in Canada who has invented a machine that rolls and reads dice.

The reason that speciality dice are expensive is mostly because of producing the moulds for them which can run into thousands of $'s. I too wish they were cheaper, but until someone finds a cheaper way of producing quality moulds or unless dice like these become very popular, they'll continue to seem expensive.

I've done some testing on the d7's, and they test as fair.

The d3's we made were cylindrical, where the surface area of each flat side was equal to the surface area of the rounded edge (each "face" was 1/3 of the total surface area of the cylinder). Ends were 1 and 2, edge was 3. Basically, it was a coin that landed on its edge as often as it did on either face.

How many rolls does a die need to go through before it is generally considered 'true'? Obviously, the more rolls the better, but is there any kind of accepted point where most experts on this would agree that a die is indeed random?
