About Our Dice Roller
Traditional dice are useful, but they are not always convenient. You might be playing a game online, teaching a probability lesson, testing a tabletop rule, or simply need a random number. In those situations, an online Dice Roller can save time and eliminate unnecessary calculations.
This virtual Dice Roller provides several common dice types in one place. You can select D4, D6, D8, D10, D12, D20, or D100 depending on the game or activity you are performing. If your game uses an unusual die, the custom option lets you create a die with anywhere from 2 to 1,000 sides.
The tool is also designed for multiple-dice rolls. Instead of rolling three physical dice separately, you can select three dice and receive all individual values together with the calculated total. This makes the Dice Roller particularly useful for RPG character attacks, damage calculations, ability checks, board games, and probability exercises.
Another useful feature is the modifier option. For example, if a game requires 1D20 + 5, the Dice Roller can generate the D20 result and automatically add the +5 modifier. Negative modifiers are supported as well.
The tool can function as a virtual dice roller for D&D, a random dice generator for classroom activities, or a general-purpose online dice generator. You do not need to download software, install an app, or create an account.
The Dice Roller also keeps a recent roll history, allowing you to review previous results. This is useful when you want to compare rolls or keep track of a game session.
For users who frequently make random selections, the tool can also provide a simple way to generate unpredictable outcomes without needing physical dice.
Most importantly, the Dice Roller is designed to be easy to understand. You select the required dice, choose how many dice to roll, optionally enter a modifier, and click Roll Dice. The result appears immediately.
Whether you are a gamer, teacher, student, game master, developer, or someone who simply needs a random result, a Dice Roller provides a convenient digital solution.

How the Dice Roller Works and Formula
The Dice Roller uses random number generation to produce a value between 1 and the selected number of sides.
For a standard die with S sides, each individual result is generated as a whole number between:
1 and S
For example, a D6 can produce:
1, 2, 3, 4, 5, or 6
A D20 can produce any integer from:
1 through 20
When multiple dice are selected, each die receives its own random result. The individual values are then added together.
Multiple Dice Formula
Dice Total = Die 1 + Die 2 + Die 3 + … + Die N
If you roll 3D6 and receive:
4, 2, 6
then:
4 + 2 + 6 = 12
If a modifier is included, the final calculation becomes:
Final Total = Sum of Dice + Modifier
For example:
2D6 + 3
with results:
5 + 4 + 3 = 12
The Dice Roller performs these calculations automatically.
The probability of any particular face on a fair S-sided die is:
P(result) = 1 / S
Therefore, a single face on a D6 has a probability of:
1 / 6 ≈ 16.67%
The Dice Roller is therefore useful not only for games but also for understanding basic randomness and probability.
How to Use the Dice Roller

Dice Roller Example Calculations
Example 1: Rolling One D6
Suppose you need a standard six-sided die.
Select D6 and click Roll Dice.
If the generated result is:
4
then the total is:
4
This is the simplest use of the Dice Roller and is suitable for board games, random decisions, and classroom activities.
Example 2: Rolling 2D6
Suppose a board game requires two six-sided dice.
Select:
2D6
Assume the results are:
3 and 5
The calculation is:
3 + 5 = 8
Therefore, the final result is:
8
Example 3: Rolling 3D6
For a character-generation activity, you might need three D6 dice.
Suppose the results are:
6, 4, and 2
The total becomes:
6 + 4 + 2 = 12
The Dice Roller displays each individual result as well as the total.
Example 4: D20 With a Modifier
An RPG character may have an attack or ability check represented by:
1D20 + 5
Suppose the D20 produces:
14
The calculation is:
14 + 5 = 19
The final result is:
19
This is one of the most useful applications of a D20 dice roller.
Example 5: Negative Modifier
Suppose your game requires:
1D20 – 2
and the generated result is:
17
The final calculation is:
17 – 2 = 15
The Dice Roller automatically handles the negative modifier.
Example 6: Custom Dice
Imagine a game requires a 30-sided die.
Select Custom, enter:
30
and roll the die.
If the result is:
23
then the final result is:
23
This makes the tool useful as a custom dice roller for games that use non-standard dice.
Key Concept Guide: Understanding Online Dice Rolling
What Is a Die?
A die is a physical or digital object that generates a random outcome. The most familiar die is the six-sided cube commonly called a D6.
A digital Dice Roller recreates this basic concept using computer-generated randomness.
What Does D6 Mean?
The letter D means die, while the number represents the number of sides.
Therefore:
- D4 = 4-sided die
- D6 = 6-sided die
- D8 = 8-sided die
- D10 = 10-sided die
- D12 = 12-sided die
- D20 = 20-sided die
- D100 = 100-sided die
What Does 2D6 Mean?
The notation 2D6 means two six-sided dice.
The first number represents the number of dice.
The second number represents the number of sides on each die.
Therefore:
3D8 = three eight-sided dice
What Does 1D20 + 5 Mean?
This notation means:
- Roll one 20-sided die.
- Add 5 to the result.
If the D20 result is 12:
12 + 5 = 17
This format is extremely common in tabletop role-playing games.
What Is a D20 Used For?
The D20 is strongly associated with tabletop RPG systems. It is commonly used for attack rolls, ability checks, saving throws, skill checks, and other random outcomes.
A D20 roller makes these calculations faster during a game.
What Is a D100 Used For?
A D100 generates a number from 1 to 100 and is often useful for percentile-based tables, random encounters, loot tables, events, and probability experiments.
What Is a Non-Conventional Dice Roller?
A non-conventional Dice Roller is useful when a game requires a die that is not commonly available as a physical product.
For example, you may need a D30, D50, D200, or another custom configuration. The custom function allows you to create these dice digitally.
What Is Dice Notation?
Dice notation is a standardized shorthand for describing dice rolls.
Examples include:
1D6
2D6
1D20+5
4D8-2
Understanding dice notation makes tabletop games easier to follow and allows you to enter common formulas into the Dice Roller quickly.
Tips & Best Practices for Using a Dice Roller
For the best experience with an online Dice Roller, always select the correct die type before rolling. A D6 and D20 produce very different ranges, so checking the selected die can prevent mistakes during a game.
When rolling multiple dice, pay attention to both the individual values and the final total. Individual results can be important in games where special rules apply to critical results, matching numbers, minimum rolls, or maximum rolls.
Use modifiers carefully. If your game requires 1D20+4, enter 4 into the modifier field rather than changing the die itself. For penalties, enter the modifier as a negative number.
For frequently used combinations, quick-roll buttons can save time. Instead of selecting D20 and manually entering one die every time, use the available preset.
If you are running a tabletop RPG session, consider keeping the Dice Roller open in a browser tab. This lets you quickly perform repeated rolls without interrupting the game.
For classroom activities, explain the difference between a single die result and the sum of multiple dice. This can help students understand random variables, probability distributions, averages, and expected outcomes.
When experimenting with custom dice, remember that changing the number of sides changes the possible range of outcomes. A D30 can produce values from 1 to 30, while a D100 can produce values from 1 to 100.
Do not assume that a small number of rolls represents the long-term average. Random results can naturally vary significantly during a short session.
For game masters, the recent roll history can also be useful for quickly reviewing what happened during a sequence of rolls.
Finally, use the copy function when you need to record or share a result. This can be particularly convenient for online gaming groups, classroom activities, and game development.
