Roll up to 10 virtual dice — from a board-game D6 to a full D&D set — with instant totals and a running history.
Pick a die type (D4, D6, D8, D10, D12, or D20), choose how many dice (1-10), and press Roll. The roller uses your browser’s cryptographic random generator — the same class of randomness used for security keys — so every face is equally likely on every roll.

How to roll dice online
1Choose your die type: D4, D6, D8, D10, D12, or D20.
2Set how many dice to roll at once (1 to 10).
3Press Roll — results and the total appear instantly, and every roll is saved to the history panel.
Yes. It uses the browser’s crypto.getRandomValues(), a cryptographically secure random number generator, rather than the weaker Math.random(). Each face has an exactly equal probability on every roll, and rolls are independent — previous results never influence the next one.
All six standard polyhedral dice: D4, D6, D8, D10, D12, and D20 — up to 10 dice at once. That covers classic board games (D6), and the full role-playing set used in D&D and other tabletop RPGs.
With two D6 there are 36 equally likely combinations. A total of 7 is most common (6 ways, 16.7%), while 2 and 12 are rarest (1 way each, 2.8%). The distribution is a triangle peaking at 7 — which is why 7 is central to dice games like craps and hazard.
Yes — the D20 mode is built for it. Roll a single D20 for ability checks and attack rolls, or multiple dice for damage. The running history panel keeps your last 50 rolls so you can show the table what you rolled.
Select 5 six-sided dice (D6) and roll. Yahtzee uses five D6 with up to three rolls per turn — the odds of rolling a Yahtzee (all five matching) in a single roll are 1 in 1,296. You can also play full Yahtzee free on Arcadia with scoring handled for you.
It runs entirely in your browser — after the page loads, rolling requires no network connection. It works on any modern phone, tablet, or desktop browser with no app install.
Yes, free. Use the embed snippet at the bottom of the page — an iframe that drops the roller into any blog, classroom page, or forum post. No attribution required beyond the built-in link.
No lost dice, no table space, verifiable fairness, and instant totals for multi-dice rolls. Physical dice can be biased by manufacturing defects — studies of mass-produced dice have measured face biases of several percent. A cryptographic roller has none.
