Is there a difference between a D20 and a Spindown dice?
In the test above there turned out to be little difference between one d20 and one spindown. It wasn’t a huge test, though, just 100 rolls and only on one dice. An unbalanced spindown, should you happen to have one, is more likely to favour a set of numbers (high or low) than an unbalanced but otherwise standard d20.

Are Spindown dice less random?
Yes, spindown dice do not have evenly distributed numbers, but if you are telling me someone can casually pick one up and control their roll to be better than mine then you are delirious. To achieve this you’d have to pick up the die, find the high/low side, and then carefully roll/drop it to get the desired result.

What are Spindown dice used for?
A spindown die is a type of die used as a life counter for Magic: The Gathering or for various other uses across card and board games. It is a D20 with the numbers laid out in a sequential pattern, to allow for the face-up number to be changed easily when a player’s life goes up or down.
Are Spindown dice balanced?
While the utility of spindowns has been expanded to similar counter roles within and outside of Magic since then, the fact remains that these were never designed to be rolled. The numbers aren’t separated and interspersed in a way that is balanced because you’re supposed to manually spin down the die from 20 to 1.

Can you use spin down dice for DND?
Dungeons & Dragons don’t use spindown dice for any of their mechanics, and so keeping to the use of a normal d20 is on flavor.
Does number placement on dice matter?
In the real world: Yes; die shapes are imperfect, often favoring opposing sides, hence the tradition of making sure opposing sides are equal on average. As explained in this answer. Having all high numbers on one side also makes it more easy to fake fair rolls, like merely spinning or skittering the die.
How do you test dice for randomness?
Place the die in the water, note which side of the die faces upwards, and then give it a flick. For reasonably balanced dice, you should see a good variety of numbers facing upwards. For badly balanced dice, you’ll probably see the same one or two faces regularly. Throw those bad dice out.
Are all D20 dice the same?
In the standard d20 numbering, small and large numbers are distributed more-or-less evenly over the die, with the following vertex sums: 39, 47, 49, 51, 52, 52, 53, 53, 54, 56, 58, and 66. Using computer search techniques, we’ve managed to find a numbering with ideally-balanced vertex sum.
What is the hardest number to roll on a dice?
Likewise, there is only one combination that yields a total of 12—when each die displays a 6. They are the least likely combinations to occur.
Why is the 1 and 4 on a dice red?
Naturally, the Emperor felt rather smug about this display of imperial fiat, and a eunuch waiting on the Emperor suggested that this phenomenal fortune should be marked by something. Thus, the Emperor decreed that in all future the ‘four’ on dice should be colored red and so it came to be.
Are Chessex dice fair?
The Chessex dice were all reasonably fair in that the rolls averaged about 10.5 (the perfect average roll on a d20), but the results were highly variable between each die (i.e. each die favoured different numbers, but the averaged total was close to 10.5). Wiz dice were similar: mostly fair, but with variable results.
Are dice rolls truly random?
The dice are meant to introduce an element of chance to these games; we expect that the outcomes of the rolls will be truly random. However, new theoretical models and high-speed movies of dice rolls of numerous shapes and sizes confirm this is not strictly the case.
Why does a d10 have a 0?
One is simply cosmetic. With nine single-digit faces and only a single two-digit face, using 0 instead of 10 allows them to print all the faces at a similar large font size. The other is, as others have noted, to make the die work better for rolling “percentiles.” In this case, you roll two ten sided dice.
What is dice jail?

Is a 3 sided dice possible?
There are already some three-sided dice on the market. Some look like weird beans. Others are just six-sided dice with the numbers 1, 2, and 3 simply appearing twice. Shapeways user Nvenom8 has come up with a truly gorgeous D3, made possible by 3D printing.
Why do dice add up to 7?
The value of the roll is indicated by the number of “spots” showing on the top. For the six-sided die, opposite faces are arranged to always sum to seven. This gives two possible mirror image arrangements in which the numbers 1, 2, and 3 may be arranged in a clockwise or counterclockwise order about a corner.
Which dice are most accurate?
They are often compared to Gamescience. Their Gemini line of dice are great looking and have a nice feel to them when rolling. Gemini dice are also considered among the most accurate dice. The mixed resin dice are easy to read and have straight precision edges.
Do metal dice roll worse?

Yes, a d100 is the same as 2d10 with one as the percentile. A d100 goes 1–100, a d10 goes 0-9. Neither allows you to roll a 0, because of the way you count a percentile dice. (00 on the percentile and a 6 on the other dice forms 6, 00 on one and 0 on the other is 100, no option will result in 0.)
What is 000 on a d100?
