Physical polyhedral dice for games like Dungeons & Dragons, Pathfinder, Call of Cthulhu, and modern board games are frequently unavailable during remote play, digital sessions, or travel. Furthermore, rolling large pools of dice manually—such as 4d6 for character attribute generation or 8d6 for spell damage—requires tedious summing and can lead to arithmetic mistakes during high-stakes game moments.
This virtual dice roller provides instant, unbiased random rolls using uniform distribution across every supported polyhedral die type: four-sided (d4), six-sided (d6), eight-sided (d8), ten-sided (d10), twelve-sided (d12), and twenty-sided (d20). Six-sided dice display authentic Unicode pip faces, while other polyhedrals show crisp, legible numerals.
For multi-die rolls, the tool computes both the total sum and the arithmetic average per die, while storing your 10 most recent rolls in a history feed so you can verify prior combat rounds or ability checks.
Roll virtual polyhedral dice for tabletop roleplaying games, board games, and random decision-making. Select from standard tabletop dice types (d4, d6, d8, d10, d12, d20, d100) or set a custom number of sides (2 to 1000), roll 1 to 10 dice simultaneously, and view individual dice outcomes, grand sum totals, and statistical averages.
Select the dice type: d4, d6, d8, d10, d12, d20, d100, or a custom number of sides.
Choose how many dice to roll at once (1–10).
Click roll to get your random results instantly.
See your recent rolls and totals.
Select 'd20' with the count slider set to 1, and click 'Roll 1d20' to generate attack rolls, skill checks, and saving throws between 1 and 20.
Select your weapon or spell damage die (e.g. d6 or d8), adjust the count slider up to 10, and click roll to inspect individual face outcomes alongside the combined sum.
Set the count to 2 on d20 and roll: select the higher number for advantage or the lower number for disadvantage according to D&D 5e rules.
Consult the 'Recent Rolls' section below the roller to audit the last 10 rolls, verifying earlier damage totals and attack values without re-rolling.

Problem
Solution
The tool rolls homogenous pools (such as 3d8 or 2d6). Rolling a mixed combination like 1d20 + 1d4 requires rolling the d20 first, then switching to d4 and checking the history feed.
Problem
Solution
The roller displays the raw dice sum. If your character sheet grants a +4 proficiency bonus or +3 strength modifier, add it to the displayed total manually.
Problem
Solution
True uniform randomness frequently produces consecutive identical numbers or apparent clusters. In small samples, streaks are statistically normal and do not indicate a flawed generator.
Problem
Solution
Rolling three 1s in a row does not make a 20 'due' on the next roll. Every virtual roll has an identical 1-in-N probability regardless of past outcomes.
Compare your multi-die roll average against the mathematical expectation (d4: 2.5, d6: 3.5, d8: 4.5, d10: 5.5, d12: 6.5, d20: 10.5) to see if you rolled above or below statistical average.
Instead of rolling 1d20 twice, slide the count to 2 to see both rolls simultaneously in a single click and pick the higher or lower die.
The history list preserves your last 10 rolls with full breakdown notation (e.g. 4d6: [5, 3, 6, 2] -> 16), ensuring disputed rolls can be verified immediately.
The slider accommodates up to 10 dice in one roll. Rolling larger pools (such as 12d6) requires rolling two batches of 6 dice and summing their totals.
All dice in a roll must share the same number of sides. The tool does not support compound formulas like 2d8 + 1d6.
Outcomes are generated using JavaScript's Math.random(), which is well-suited for tabletop games and casual play, but not certified for cryptographic or regulated real-money gambling.
Game mechanics like exploding dice on maximum rolls or '4d6 drop lowest' must be calculated manually from the displayed individual roll values.

Common questions regarding virtual dice rolling, polyhedral dice notation, probability averages, and browser pseudo-random number generation.
Standard RPG dice notation: XdY means roll X dice with Y sides and sum the results. Examples: 1d20 = roll one 20-sided die (used for attack rolls and ability checks in D&D 5e). 2d6 = roll two 6-sided dice and sum (used for weapon damage). 1d4 = one 4-sided die. 1d8 = one 8-sided die. 1d10 = one 10-sided die. 1d12 = one 12-sided die. 1d100 (or d%) = two d10s rolled as tens and units digits.
The d20 (20-sided die) is the core mechanic die in Dungeons & Dragons and many other tabletop RPGs. It determines the outcome of almost all contested actions: attack rolls, skill checks, saving throws, and ability checks. A natural 20 (rolling a 20 on the die, before modifiers) is a critical hit in D&D 5e - an automatic success with bonus effects. A natural 1 is a critical failure - an automatic miss regardless of modifiers.
Average roll = (minimum + maximum) / 2. D4: average 2.5. D6: average 3.5. D8: average 4.5. D10: average 5.5. D12: average 6.5. D20: average 10.5. For multiple dice, multiply single die average by number of dice: 2d6 average = 3.5 × 2 = 7. These averages are important for game balance calculations - a weapon dealing 2d6 damage averages 7 per hit versus a weapon dealing 1d12 which also averages 6.5.
Advantage: roll two d20s, take the higher result. Disadvantage: roll two d20s, take the lower result. Advantage effectively increases the average roll from 10.5 to 13.8; disadvantage decreases it to 7.2. In this dice roller, roll two d20s separately and apply the higher or lower result manually. Some digital dice rollers have built-in advantage/disadvantage modes that automate this.
In D&D 5th Edition, rolling a natural 20 on an attack roll (the d20 shows 20 before adding modifiers) is a critical hit. On a critical hit, you roll all damage dice twice and add them together, then add ability modifiers normally. Example: a longsword normally deals 1d8+3 damage. On a critical hit: 2d8+3 damage. Some class abilities (Rogue's Brutal Critical) add extra dice on critical hits. A natural 1 on an attack roll is an automatic miss.
