20-sided die (d20)

A 20-sided die, commonly referred to as a d20, is a polyhedral die used primarily in tabletop role-playing games, such as Dungeons & Dragons. It features 20 triangular faces, each numbered from 1 to 20. Players roll the d20 to determine the outcome of their actions, with higher numbers typically indicating better results. The die provides a random result within its range, contributing to the game's unpredictability and strategic elements. Its use in gameplay enhances decision-making, skill checks, and combat scenarios, making it a vital tool for players in these immersive experiences.
