A dice roller is used to simulate rolling physical dice for tabletop games like Dungeons & Dragons, Pathfinder, and other RPGs. It generates random numbers just like real polyhedral dice, and is also useful for board games, probability exercises, classroom activities, and any situation requiring random number generation.
In Dungeons & Dragons, d20 refers to a 20-sided die (icosahedron). It is the most iconic die in D&D, used for attack rolls, ability checks, and saving throws. Players roll a d20 and add relevant modifiers to determine success or failure of their actions.
Advantage means you roll two d20 dice and take the higher result, giving you a better chance of success. Disadvantage means you roll two d20 dice and take the lower result, reducing your chances. These mechanics are commonly applied by the Dungeon Master based on favorable or unfavorable conditions.
Use the multi-dice feature by entering the number of dice you want to roll and selecting the dice type. For example, entering 3 and selecting d6 will roll three six-sided dice, showing each individual result along with the total sum. This is useful for rolling damage dice or generating ability scores.
A d100, also called a percentile die, generates a number from 1 to 100. It is commonly used in D&D for wild magic surges, random loot tables, critical hit/fumble tables, and any roll requiring percentage-based outcomes. It is typically rolled using two d10 dice (one for tens, one for ones).
