The Dice Roller lets you roll virtual dice online — from a standard six-sided die to the full polyhedral set of d4, d6, d8, d10, d12, and d20. Choose your dice type, roll up to eight at once, and get an instant total. Perfect for board games, tabletop RPGs like Dungeons & Dragons, or any time you need dice and don’t have a physical set nearby.
Every roll is genuinely fair: results come from your browser’s cryptographically secure random generator, so each face is equally likely and impossible to predict. Six-sided dice show classic pip faces, and everything runs locally in your browser.
How to roll the dice
- Pick a dice type — d4, d6, d8, d10, d12, or d20.
- Set how many dice to roll (up to eight) with the plus and minus buttons.
- Press Roll and watch the dice tumble to their result.
- Read each die and the running total below — roll again as many times as you like.
Which dice can I roll?
- d6 — the classic six-sided die, shown with traditional pips.
- d4, d8, d10, d12, d20 — the polyhedral dice used in tabletop RPGs, shown as numbers.
- Up to eight dice at once, with an automatic total (e.g. roll 3d6 for a damage roll).
Are the rolls fair?
Yes. Each die is rolled using the Web Crypto API (crypto.getRandomValues) with a technique that removes the small statistical bias a naïve “random modulo” approach can introduce. That means every face has an exactly equal chance, and past rolls never influence future ones.
Because it’s truly random, you’ll sometimes see repeated numbers or unlikely-looking totals — that’s expected, not a bug.
Frequently Asked Questions
Can I roll multiple dice at once?
Yes — choose up to eight dice with the plus and minus buttons. The tool rolls them all together and shows each result plus the combined total, so “3d6” or “2d20” takes one click.
Is this good for Dungeons & Dragons?
Absolutely. It supports the full polyhedral set — d4, d6, d8, d10, d12, and d20 — which covers standard D&D and most tabletop RPG rolls, including rolling several dice for a single total.
Are the dice actually random?
Yes. Rolls use your browser’s cryptographically secure random generator with bias removed, so every face is equally likely and the result can’t be predicted or influenced by previous rolls.
Does it work on mobile?
Yes. The dice roller runs entirely in your browser and works on phones, tablets, and computers, with no app to install and no sign-up.
Does it save my rolls?
No. Results exist only in the page while it’s open and are cleared when you reload. Nothing is uploaded or stored on a server.
