About this tool

Whether you’re playing a board game without the physical dice or running a tabletop RPG, this roller handles any dice you need. Pick the number of dice and sides, add a modifier for those “+2 to hit” moments, and roll.

Each result shows the individual dice alongside the total, so it’s easy to follow. The randomness comes from your browser’s cryptographic generator, making every roll fair and unpredictable — and entirely private.

Frequently asked questions

Is the randomness fair?

Yes. Rolls use the browser's cryptographic random generator with rejection sampling, so every face is equally likely and there's no modulo bias.

Can I roll dice like d20 or d100?

Absolutely. Use the quick presets for d4 to d20, or type any number of sides up to 1000 for unusual dice.
