Know your POLYHEDRONS

A guide to the standard set of 7 RPG Dice.

Most of the dice are given names like d6 or d20. The ‘d’ is for dice and the ‘number’ refers to the number of faces / sides the dice has.

This four-sided often referred to as the d4. You typically read the number that is the right side up and oriented the right way.

This is a d4 – a tetrahedron

We all know this one… the six-sided cube – the d6.

cube

The eight-sided one is often referred to as – the d8.

octahedron

This d 10, is the ten-sided dice is the one with only single digits on each face.

deltohedron

There is another ten-sided dice but it’s the one with the double digits (00-90). We call this the PERCENTILE dice.

deltohedron

This dice is usually thrown together with the d10 to produce a ‘percentage’ result. The digits on the percentile dice represents values in the tens-place while the d10 digit is for the ones-place. It’s kind of tricky for newbies but we’ll try to give you some simple examples to explain;

0 tens + 1 ones = 1%
ten + 0 ones = 10%
ten + 8 ones = 18%

So… how do you get 100%?

This is the only way to get 100% and won’t count it as a 0% because… that would be mean.

Next, we have the twelve-sided dice that we call – the d12.

dodecahedron

Finally, the one where we roll the most during most RPGs… the 20-sided dice that determines the fates of many. That roll to see if your character does something heroically amazing, of he fails in epic proportions… both tales befitting to be recalled many times over as your group is bound to reminisce – the icosahedron – d20.
