Polyhedral dice are multi-sided dice used in various tabletop games, including Dungeons & Dragons and other role-playing games. Unlike standard six-sided dice, polyhedral dice can have different numbers of sides, such as four, eight, ten, twelve, or twenty. Each type of die is typically represented by a specific shape, allowing players to roll for different outcomes based on the game mechanics. These dice are often made from materials like plastic or resin and come in various colors and designs. Players use polyhedral dice to determine the results of actions, such as attacks or skill checks, adding an element of chance and excitement to gameplay.
