## Geometry of dice - dice shapes

If our dice roll generator is not enough, and you prefer dice that you can roll yourself, here are some fun facts about dice shapes.
Dice must be constructed in a way there is an equal probability of each outcome. Geometrically, the typical dices are regular polyhedrons, so three-dimensional shapes with identicall faces and corners, and straight edges. They are also known as Platonic solids.

Dice type

Geometrical shape

4-sided

Tetrahedron

6-sided

Cube

8-sided

Octahedron

12-sided

Dodecahedron

20-sided

Icosahedron

Another popular dice - 10-sided dice is created with a figure with kite-shaped faces. It's called a pentagonal trapezohedron.

It's most tricky to create odd-number-sided dices. For example, you can't create a 3D shape with 3 sides. But you can create a cube with each number (1, 2, 3) displayed two times. For other odd numbers you can create prisms. That means shapes with regular polygons at the top and bottom, and any number of sides.

Generally, there isn't one way to make a dice. Even most popular 6-sided dice can be a cube, but it can also be a prism, a trapezohedra, or a dipyramid.
