What Is an Online Dice Roller?
An online dice roller is a virtual simulation of physical polyhedral dice, generating random numbers within a defined range at the click of a button. Unlike physical dice that can develop wear, bias, or manufacturing imperfections over time, a high-quality virtual dice roller like ours uses the Web Crypto API to guarantee statistically perfect outcomes — making every roll as fair as a factory-fresh die in ideal conditions.
Our random dice roller supports all standard RPG polyhedral dice: the D4, D6, D8, D10, D12, D20, and D100 (percentile). It's purpose-built for tabletop role-playing games like Dungeons & Dragons (D&D 5e), Pathfinder, Call of Cthulhu, GURPS, and countless others, but equally useful for board games, math education, probability demonstrations, and classroom exercises.
Best practices when using a dice roller include selecting the correct die type for your game system, applying Advantage or Disadvantage mechanics where rules require, and always adding the appropriate ability or proficiency modifier to your total. For character creation, the 4d6-drop-lowest method — available as a quick preset — produces ability scores with the same distribution as rolling physical dice at the table.
Rolling dice online removes the risk of losing dice under furniture, eliminates disputes about whether a die fell off the table, and lets you play remotely. Whether you need a quick D20 roll for an attack, a D6 dice roll for damage, or a percentile D100 for skill checks, this free tool handles it all instantly — no downloads, no accounts, no ads.

Yes. Click the "Custom" die button, enter any number of sides between 2 and 10,000, and roll as normal. Useful for probability exercises, unusual game systems, or just experimentation.
A standard D&D set uses D4, D6, D8, D10, D12, D20, and D100 (percentile, or two D10s). All of these are supported directly in our dice roller with dedicated buttons.
