Regular polyhedral dice with multi-sided dice

Regular polyhedron dice are dice made according to the geometric model of regular polyhedron. The so-called regular polyhedron means that all faces of the polyhedron are congruent regular polygons and all polyhedron angles are congruent polyhedron angles. For example, four faces of a regular tetrahedron (that is, a regular quadrangle pyramid) are all congruent triangles, and each vertex has a three-sided corner. * * has four three-sided corners, which can completely overlap, that is, congruence, and there can be countless polyhedrons, but there are few types of regular polyhedrons.

According to euler theorem, there are only five regular polyhedrons: regular tetrahedron, regular hexahedron, regular octahedron, regular dodecahedron and regular icosahedron. Because of the characteristics of regular polyhedron, the probability of random numbers obtained by regular polyhedron dice is equal.

Irregular polyhedral dice (such as 5 faces, 10 faces, 24 faces, etc.). It may also be used in actual games, but this does not mean that the probability of landing on each side is different. See below for details.
