    FAQ

    Is the dice roller free to use?
    Yes, it is completely free. No registration required, and it works the moment you open it in your browser.
    Are the rolls truly fair?
    Yes. We use the browser's cryptographic random API (crypto.getRandomValues) with rejection sampling to remove modulo bias, so every face has an exactly equal probability.
    Can I use dice notation like "2d6+3"?
    Yes. Enter notation such as "2d6+3", "1d20+5", or "3d8" in the Dice Notation field and apply it. Combined notation like "2d6+1d8+2" is also supported.
    How many dice can I roll at once?
    You can roll up to 100 dice at once, which is handy for TRPG attacks or batch random draws.
    How is d100 (percentile) rolled?
    d100 generates a single integer from 1 to 100 with equal probability, giving the same range as combining two d10 at a physical table.
    Is my data saved anywhere?
    No. Your inputs and roll results are never sent to or stored on our servers. Everything happens locally in your browser, protecting your privacy.
    Does it work on smartphones?
    Yes, it works on all devices including smartphones, tablets, and PCs, with full touch support.
