A d20, or twenty-sided die, is a die that has an equal chance of rolling the integers from 1 to 20. The standard shape of a d20 is a regular icosahedron, in which form it appears in the standard 7-dice set used in role-playing games like Dungeons & Dragons. The d20 is closely connected with Dungeons & Dragons (being used in its standard resolution mechanics), and is an iconic symbol of the role-playing hobby in general. A regular icosahedron is a polyhedron with 20 faces that are all equilateral
