How to Roll a D100 with Percentile Dice in Tabletop RPGs - Mastering the Art of Rolling a D100

Introduction to the D100 in Tabletop RPGs

In tabletop role-playing games (RPGs), randomness is a crucial part of the experience, and the d100 (percentile dice) is one of the most commonly used tools to generate random outcomes. But how exactly do you roll a d100 with just two dice? This guide will walk you through the process of how to roll a d100 effectively and fairly, ensuring you understand how to achieve every possible result, from 1 to 100.

What is a D100 (Percentile Dice)?

A D100, also known as percentile dice, generates a random number between 1 and 100. It's frequently used in RPGs when a broader range of outcomes is necessary, such as determining the success or failure of specific actions or generating random encounters. Understanding how to roll a d100 can enhance your experience in these scenarios.

How to Read Percentile Dice

Percentile dice typically consist of two ten-sided dice (d10s). One die represents the tens place, and the other represents the ones place. To read a percentile roll:

• First Die: Represents the tens place (00-90).
• Second Die: Represents the ones place (0-9).

Combine the results to get your number. For example, a roll of '30' on the first die and '7' on the second die would result in a 37.

What Does 00 Mean on Percentile Dice?

On a percentile die, '00' does not indicate zero but rather signifies that the tens place is zero. When paired with any number on the second die, it forms a number ending in zero. For instance, '00' on the first die and '3' on the second die results in a 3.

What is 100 on a D100?

To roll a 100, you need to roll a '90' on the first die and a '0' on the second die. In this context, '00' on the first die represents zero in the tens place, and '0' on the second die represents zero in the ones place, combining to form 100. For more details, you can refer to D&D Beyond's guide on dice rolling.

Uses of Percentile Dice in RPGs

Percentile dice are versatile and used for various purposes in RPGs, including:

• Skill Checks: Determine if a character succeeds in a specific skill or action.
• Random Encounter Generation: Roll to see what random events occur during gameplay.
• Broad Probability Ranges: Use when outcomes with a wide range of probabilities are required.

Are Percentile Dice Fair?

When rolled correctly, percentile dice are fair, providing an equal probability for each number between 1 and 100. Ensure both d10s are rolled simultaneously without bias for the best results.

Is There a 100-Sided Die?

While there are dice with more than 100 sides, a standard 100-sided die is rare. Instead, most RPG players use two d10s to simulate a D100 roll, offering a practical and fair alternative.

How to Ensure a Fair D100 Roll

To ensure your D100 roll is fair:

1. Roll both d10s simultaneously.
2. Use a dice tray or shake the dice in a cup to randomize the roll.
3. Combine the results correctly, as described above.
