What is a Virtual Dice Roller?

A virtual dice roller is an online tool that simulates rolling physical dice for tabletop role-playing games (RPGs), board games, and other gaming applications. Our dice roller supports all standard RPG dice types (d4, d6, d8, d10, d12, d20, d100) plus custom dice with any number of sides (2-1000).

Using , our dice roller provides truly random results that are mathematically fair and unbiased - perfect for D&D (Dungeons & Dragons), Pathfinder, Warhammer, Call of Cthulhu, and any tabletop gaming system.

Standard RPG Dice Types

D4 - Four-Sided Die

Used for low damage spells, daggers, and certain saving throws in D&D. Numbered 1-4.

D6 - Six-Sided Die

The most common die. Used in countless board games, damage rolls, and ability scores. Numbered 1-6.

D8 - Eight-Sided Die

Common for weapon damage (longswords, battleaxes) and hit dice for medium classes. Numbered 1-8.

D10 - Ten-Sided Die

Used for heavy weapon damage and percentile rolls (when paired with another d10). Numbered 1-10 or 0-9.

D12 - Twelve-Sided Die

Used for greataxe damage and barbarian hit dice in D&D 5e. Numbered 1-12.

D20 - Twenty-Sided Die

The iconic D&D die. Used for attack rolls, saving throws, ability checks, and skill checks. Numbered 1-20.

D100 - Percentile Die

Used for random encounter tables, loot tables, and percentage-based mechanics. Results 1-100.

Custom Dice

Create dice with any number of sides (2-1000) for custom game systems and unique mechanics.

Understanding Dice Notation

Dice notation is the standard way to describe dice rolls in tabletop gaming. Our dice roller supports all common notation formats:

NdS - Roll N dice with S sides (e.g., 3d6 = roll 3 six-sided dice)

NdS+M - Roll and add modifier M (e.g., 1d20+5 = roll d20 and add 5)

NdS-M - Roll and subtract modifier M (e.g., 2d8-2 = roll 2d8 and subtract 2)

4d6 drop lowest - Roll 4d6, remove the lowest die (D&D ability scores)

NdS keep highest X - Roll N dice, keep only X highest (advantage mechanics)

Example: "4d6 drop 1 lowest +2" means:

Roll 4 six-sided dice

Remove the lowest die

Add the remaining 3 dice together

Add 2 to the total

How to Roll Dice

[STEP 1] Select Dice Type

Choose from standard RPG dice (d4, d6, d8, d10, d12, d20, d100) or select custom to create dice with any number of sides (2-1000).

[STEP 1] Configure Parameters

Set the number of dice to roll (1-100), add modifiers (-20 to +20), and choose how many times to roll (1-25 rolls).

[STEP 1] Apply Advanced Mechanics (Optional)

Enable drop lowest to remove N lowest dice from the total, or use keep highest to keep only the N highest dice. Perfect for D&D ability scores (4d6 drop lowest) or advantage mechanics.

[STEP 1] Use Quick Presets

Select from common presets like D20 Check, D20+5 Attack, Ability Score (3d6), D&D Ability (4d6 drop lowest), Fireball (8d6), or Percentile (1d100) for instant configuration.

[STEP 1] Roll & Analyze

Click the roll button to generate results. View individual dice values, subtotals, modifiers, and final totals. For multiple rolls, see statistics including average, highest, lowest, and sum of all rolls. Export results as TXT, CSV, or JSON.

Frequently Asked Questions

How random are the dice rolls? ▶

Our dice roller uses cryptographically secure random number generation (CSPRNG), which provides mathematically fair randomness. Each face of a die has exactly equal probability of being rolled, ensuring fair and unbiased results suitable for serious gaming and competitive play.

This notation means roll 4 six-sided dice, then discard the lowest die and add up the remaining 3 dice. This method is commonly used in D&D 5e for generating ability scores, as it creates slightly higher average scores (10.5 vs 10.5 for straight 3d6) while maintaining randomness.

Currently, each roll generates the same dice type. To roll different dice types (e.g., 1d20 + 2d6), you would need to make separate rolls and add them together manually. However, you can use the quick presets to switch between common combinations quickly.

Both achieve similar results but work differently: "drop lowest 1" from 4d6 removes the single lowest die, while "keep highest 3" from 4d6 keeps only the 3 highest dice. For the same numbers, they produce identical results. Use whichever notation you prefer.

Absolutely! Our dice roller is perfect for online D&D, virtual tabletop gaming, or remote RPG sessions. The cryptographically secure randomness ensures fairness, and you can share results via export functionality or screenshots.

A d100 or percentile die represents a roll from 1-100. Physically, this is often rolled using two d10 dice (one for tens, one for ones). It's used for percentage-based mechanics, random encounter tables, loot generation, and systems like Call of Cthulhu that rely on percentile rolls.

Yes! Select "custom" as the dice type and you can create dice with anywhere from 2 to 1000 sides. This is useful for homebrew game systems, special mechanics, or unique gaming scenarios that do not use standard dice.

Modifiers are numbers added to or subtracted from your dice total. In D&D, these typically represent ability modifiers, proficiency bonuses, or magical bonuses. For example, if you roll 1d20+5 and get a 14 on the die, your total is 19 (14+5).
