Virtual Dice Roller App for Tabletop RPGs and Board Games

This virtual dice roller works for any game that uses dice. Dungeons & Dragons sessions, board game nights, classroom activities, or spontaneous decisions where you let chance pick the outcome.

It runs in your browser on any device. Phone, tablet, or desktop. You get the same fast experience everywhere, so there is nothing to install from an app store.

Whether you need a single d20 for a D&D attack roll or a handful of six-sided dice for Yahtzee, the tool handles it in one tap.

How to Roll a Die on This Site

1. Choose the number of dice. Set how many dice you want to roll at once.
2. Pick the number of sides. Select from common options like d4, d6, d8, d10, d12, d20, or d100. You can also enter a custom number of sides.
3. Add a modifier (optional). Enter a positive or negative number to add to the total. Useful for D&D ability checks and attack rolls.
4. Tap Roll. Your random result appears immediately, showing each individual die face and the combined total.

That's the entire setup. Adjust the settings and roll again as many times as you need.

Customize Your Dice Roll: D20, D8, D4, and More

Standard six-sided dice cover most board games, but tabletop RPGs demand variety. Polyhedral dice (dice with more than six faces) are essential for systems like Dungeons & Dragons, Pathfinder, and many other RPGs.

Here is a quick reference for the most common polyhedral dice:

• d4: four-sided die, often used for small weapon damage
• d6: the standard cube, used in board games and RPG ability scores
• d8 : eight-sided die, common for medium weapon damage
• d10 : ten-sided die, used in percentile rolls and various RPG systems
• d12 : twelve-sided die, used for heavy weapon damage
• d20 : twenty-sided die, the backbone of D&D attack rolls, saves, and checks
• d100 : one-hundred-sided die (or two d10s read as percentile), used for random encounter tables and loot rolls

Roll Any Number of Dice

Some situations call for more than one die at a time. Rolling 2d6 for Monopoly, 4d6 for D&D character creation, or even 100 dice for a probability experiment are all supported.

Set the dice number to whatever you need. The roller displays each individual result alongside the total, so you can see every face that came up.

Dice Roll Example for D20 and Other Polyhedral Dice

A common D&D example: your character swings a longsword. You roll 1d20 + 5 for the attack. If the d20 shows 14, the total is 19.

On a hit, you roll 1d8 + 3 for damage. The d8 lands on 6, so you deal 9 damage.

With this dice roller, you set up each roll in seconds. Pick the die type, add the modifier, and tap Roll. No mental math needed for the modifier since the tool calculates the total for you.

Random Number and How the Online Dice Roller Works

The online dice roller uses a pseudo-random number algorithm built into your browser's JavaScript engine. When you tap Roll, the tool generates a random number between 1 and the number of sides you selected.

A pseudo-random number generator (PRNG) produces sequences that are statistically random enough for any dice game. The results pass standard randomness tests and are perfectly fair for tabletop play, board games, and casual decisions.

Random Dice Roll vs. Random Number Generator

A random number generator (RNG) picks any number in a defined range. A dice roll is a specific type of RNG where the range matches a physical die: 1 to 6, 1 to 20, and so on.

How random is a dice roll here? Each side has an equal probability of appearing on every roll. A d6 gives each face a 1-in-6 chance. A d20 gives each face a 1-in-20 chance. The algorithm does not favor any outcome.

True randomness (from atmospheric noise or hardware entropy) exists at sites focused on cryptography. For rolling dice in a game, a PRNG is more than sufficient. Physical dice actually introduce more bias from manufacturing imperfections and throwing habits than a well-implemented algorithm.

Roll Dice for Tabletop Games, RPGs, and Dungeons & Dragons

D&D and other tabletop RPGs rely on dice for nearly every action. Attack rolls, saving throws, damage, skill checks, and random encounters all need quick, random results.

This dice roller supports the full standard set: d4, d6, d8, d10, d12, d20, and d100. Add a modifier to match your character sheet bonuses, and you have a complete digital dice tray for immersive RPG sessions.

It is especially useful for:

• Online or remote D&D sessions over video chat
• Quick rolls when your physical dice are not handy
• Dungeon masters generating random encounters on the fly
• New players who do not own a polyhedral dice set yet

Quick Dice Roller for Yahtzee, Monopoly, and Board Games

Board games typically use standard six-sided dice. Set the roller to 2d6 for Monopoly or Risk. Set it to 5d6 for Yahtzee.

The tool shows each individual die face, which matters in games like Yahtzee where you need to see every result separately. Roll fast, play faster.

Features That Support Every Dice Game

• Any die type. Standard options from d4 to d100, plus custom dice with any number of sides.
• Multiple dice. Roll up to 100 dice at once.
• Modifiers. Add or subtract a fixed number from the total.
• Instant results. No loading screens or animations blocking your game.
• Works on any device. Phone, tablet, or computer. No app download required.
• Free to use. No subscriptions, no paywalls.

Customize Dice Number, Sides, and Modifiers

Customization is straightforward. Every setting is visible on the page:

• Dice number: how many dice to roll (1, 2, 5, 10, or more)
• Sides: how many faces each die has (4, 6, 8, 10, 12, 20, 100, or any custom value)
• Modifier: a number added to (or subtracted from) the total result

This covers virtually every tabletop game scenario, from a simple coin-flip (d2) to a d100 percentile roll with a +5 modifier.

Online Dice Roller App vs. Physical Dice

Physical dice have a satisfying feel. The weight, the sound, the clatter across the table. Many players love that tactile experience, and nothing fully replaces it.

But a virtual dice roller has practical advantages:

Neither option is objectively better. Many players use both. Physical dice at the table, virtual dice on the go or during remote sessions.

Privacy on This Dice Roller Site

This site does not require an account. You do not log in, and no personal data is collected to use the dice roller.

Are my settings saved to an account? No. There is no account system. Your dice settings are handled locally in your browser. Nothing is transmitted to a server.

The page does not track your rolls or store your history remotely. You roll, you see the result, and that is it.

Probability and What a Dice Roll Can Estimate

Every fair die gives each face an equal chance of appearing. The probability of any single outcome on a die with n sides is:

Probability = 1 / n

• d6: each face has a 16.67% chance
• d20: each face has a 5% chance
• d100: each face has a 1% chance

When you roll multiple dice and sum them, the distribution shifts. Rolling 2d6 produces results from 2 to 12, but 7 is the most common total (six combinations out of 36). The extremes (2 and 12) each have only one combination.

This matters for game design and strategy. In games like Risk or Settlers of Catan, understanding the probability curve of 2d6 helps you make better decisions.

This dice roller is a quick estimation and play tool. It gives you fair, random results for games and decisions. It is not a certified random source for cryptographic or scientific purposes.
