Roll virtual dice online free - no login. Choose any standard dice (d4, d6, d8, d10, d12, d20) or set a custom number of sides and dice. Roll multiple dice at once with history tracking.
Physical dice for tabletop games, board games, and probability exercises are often unavailable or awkward to use in digital-first contexts. A virtual dice roller provides the full range of standard dice with the same statistical properties as physical rolling.
Roll any standard dice - D4, D6, D8, D10, D12, D20 - or custom-sided dice. Roll multiple dice simultaneously and see individual results plus the total.
Roll dice for tabletop RPGs (D&D, Pathfinder) when physical dice are unavailable, decide game actions during board game digital play-throughs, use D6 for statistical probability demonstrations, generate random encounter outcomes for game masters, roll dice for learning probability in educational settings, and settle random decisions in multi-player games.
The most common question is about dice notation. Standard RPG dice notation: XdY means roll X dice with Y sides. 2d6 = roll two 6-sided dice and sum them. 1d20 = roll one 20-sided die. 3d4 = roll three 4-sided dice and sum. The notation is universal across most tabletop games.
Select the dice type: d4, d6, d8, d10, d12, or d20.

Common questions about this tool and how to use it.
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.
