Is there a standard way to number the faces of a 20-sided die?
There are 20!=2432902008176640000 ways to map numbers 1...20 onto the faces of the regular icosahedral d20 die, but many of these configurations are rotationally equivalent. The size of the rotational symmetry group |G|=60. So, there are. 20!/|G| = 2432902008176640000/60 = 40548366802944000 rotationally distinct configurations of the d20 die ...
Why do the opposing sides of a D20 generally add up to 21
2013年11月4日 · Another reason might be that originally 6-sided dice used little holes to mark the numbers. The material removed to create a 6 is more than that to create a 1. As such, the different sides of a die had different weights. To balance the weight across all three directions of the die, opposing numbers were chosen to balance out the different ...

2020年11月27日 · The "d" notation introduces a dice-specific algebra that allows you to find easily the equivalence of dice roll. e.g.: roll 30 times a d10 dice = 30d10 = 3d10×10 = take your 3 d10 dice and roll them 10 times. p.s.: I think the "d" stands for "dice" because a d6 has 3 spatial dimensions and only one numerical.

Are there any dice games you can play with a standard 7-die set?
Are there any dice games that you can play with a standard role-playing 7-die set (d4, d6, d8, d10, d%, d12, d20)? Maybe you have some time to kill before your tabletop session starts, or during a break. It'd be nice to have a game that doesn't require anything beyond this set of dice. I'm open to games that can be played alone or with friends.

2016年8月19日 · For some corner cases, such as marking counters on Magic: The Gathering cards, I prefer 12mm dice, as you don't need to roll them, they obscure the card less, and it's easier to carry large quantities of them. As for wood dice, which ship more frequently than plastic dice in older German tabletop boxes that I own, those have 15mm, 18mm and 30mm ...

2012年6月1日 · If 20 and 19 are next to each other, adding a weight to the opposite side of the dice would increase the chances of rolling a high number. In other words, it's easier to make a trick dice if it's a countdown dice. This matters if only one person uses the trick dice, but it sounds like this isn't the case here.

2023年8月25日 · Use a coinflip app, or physical 4- or 6-sided dice (calling odd/even or above/below half instead of heads/tails). Both solutions fulfill all your criteria.

Why are the pips on dice organized the way they are?
2019年11月29日 · 5. Rotation Invariance. The reason the pips are configured in the pattern they are is so they look the same no matter what angle you're looking at them, as much as possible.
