Dungeons & Dragons (D&D)

Dungeons & Dragons (D&D) uses various types of dice for gameplay, each denoted by a "d" followed by the number of sides on the die. The most common ones are:

d4 (Four-sided die): A pyramid-shaped die with numbers 1 through 4.
d6 (Six-sided die): The standard six-sided die commonly used in many games.
d8 (Eight-sided die): A polyhedral die with numbers 1 through 8.
d10 (Ten-sided die): A 10-sided die numbered from 0 to 9 or 1 to 10.
d12 (Twelve-sided die): A 12-sided die with numbers 1 through 12.
d20 (Twenty-sided die): A 20-sided die with numbers 1 through 20.
In addition to these, there's also the d100 or percentile die, which is usually represented by two ten-sided dice, one representing the tens and the other representing the units.

Players use these dice to determine outcomes of various in-game actions, such as attacking an enemy, saving throws, or determining the success of skill checks. The Dungeon Master (DM) often calls for specific dice rolls based on the situation, and the players roll the appropriate dice to see the outcome.
