Dice & Coin Roller

Roll any combination of dice — D2 through D20 and beyond — or flip a coin, using your browser’s cryptographically secure random number generator rather than a predictable pseudo-random function.

Useful for tabletop games, quick decisions, or generating random test values, without digging out physical dice or trusting a basic random number generator that isn’t actually well-distributed.

Select your die type and how many to roll at once, and tap to roll — results display individually and as a total. Flip a coin with the same one-tap simplicity. Keep a running history of recent rolls if you’re tracking results over a longer session.

Frequently asked questions

Is the randomness actually fair, or could certain numbers come up more often? Rolls use a cryptographically secure random source, giving every face and every flip outcome a genuinely equal, unbiased chance, unlike some simpler random implementations that can have subtle statistical bias.

Can I roll unusual combinations, like multiple different die types at once? Yes, add multiple dice of different types to a single roll (like a D20 and two D6s together for a tabletop game mechanic) and see each result broken out individually alongside the combined total.

Does this save my roll history between visits? Roll history persists for your current session but isn’t saved permanently between visits, so treat it as a running log for one sitting rather than long-term record-keeping.
