About this tool
This dice roller rolls virtual polyhedral dice — d4, d6, d8, d10, d12, d20 and d100 — right in your browser. Pick a die type, choose how many to roll (anywhere from one to twenty at a time), and it shows each result plus the combined total. It is built for tabletop role-playing games, board games and any moment you need a quick, fair throw without hunting for physical dice. Every roll is drawn from your browser's cryptographic random number generator, so the outcomes are genuinely unbiased rather than a predictable pattern.
Frequently asked questions
Are the rolls truly random and fair?
Yes. Each roll uses your browser's built-in cryptographic random number generator — the same class of randomness used for security — rather than a simple predictable formula. That means every face has an equal chance on every throw, with no memory of previous results and no hidden bias toward high or low numbers. Rolling a d20 several times can still produce streaks, exactly as fair physical dice would.
Which dice can I roll, and how many at once?
You can roll the standard polyhedral set — d4, d6, d8, d10, d12, d20 and d100 — covering everything from a four-sider to percentile rolls. Choose any number from one to twenty dice in a single throw, and the tool lists each individual result alongside their combined total. That makes it easy to handle attack rolls, damage dice or a fistful of d6 for a board game in one click.
Does it work offline, and do my rolls stay private?
Yes. The dice roller runs entirely in your browser with local JavaScript, so once the page has loaded it keeps working even without an internet connection. Nothing about your rolls is sent to or stored on a server — the random numbers are generated on your own device. You can leave a tab open during a game night and roll as often as you like, completely privately.
