Dice Roller
Roll virtual dice online — d4, d6, d8, d10, d12 and d20, up to 10 at once — with animated rolls, totals and roll history. Great for D&D.
About the Dice Roller
This free dice roller simulates every common polyhedral die: the classic six-sided d6 plus the d4, d8, d10, d12 and d20 used in Dungeons & Dragons and other tabletop RPGs. Roll up to 10 dice at once, watch them tumble through a quick animation, and get each die's value alongside the automatic total.
Results come from your browser's cryptographically secure random number generator with proper unbiased sampling, so every face is exactly equally likely — no loaded dice here. A history panel keeps your last ten rolls with their individual values and totals, useful for tracking a game session or checking a suspicious streak.
Use it when the real dice are lost under the sofa: board games like Monopoly or Yahtzee (2×d6), D&D ability checks (d20), damage rolls (like 3×d6), classroom probability lessons, or generating quick random numbers for any game you invent.

Frequently Asked Questions
Are the dice rolls truly random?
As close as software gets. Each roll uses crypto.getRandomValues — the same cryptographically secure generator browsers use for security keys — with rejection sampling to remove modulo bias, so every face has an exactly equal chance. That makes these rolls statistically fairer than many physical dice, which often have tiny manufacturing imbalances.
What do d4, d8, d10, d12 and d20 mean?
The "d" notation is standard in tabletop gaming: the number after d is how many faces the die has. A d6 is the familiar cube; a d20 has twenty faces numbered 1–20. Dungeons & Dragons uses the full set — d20 for attack rolls and ability checks, d4 through d12 for damage — which is why the notation appears in phrases like "roll 3d6".
Can I roll multiple dice and get the total automatically?
Yes. Set the number of dice up to 10 and every roll shows each individual die plus the summed total — so rolling 3×d6 for a D&D strength score or 2×d6 for Monopoly needs zero mental arithmetic. The history panel keeps your last ten rolls with their totals in case you need to look back.
Can I use this dice roller for D&D and other RPGs?
Absolutely — it covers the complete standard polyhedral set used by D&D, Pathfinder and most tabletop RPGs. Roll a single d20 for checks and saves, or multiple damage dice at once. There's no d100 die, but you can roll a d10 twice (tens then units) the same way percentile dice work at a real table.
Why did I get the same number several times in a row?
Streaks are a normal property of true randomness, not a sign the roller is broken. Rolling a d6, the chance of the same value twice in a row is 1 in 6 — it should happen regularly. Independent random events have no memory, so a die that just showed 20 is neither more nor less likely to show 20 again.
