Frequently asked questions

Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.

When should I use the Dice Roller?

Use it when your task matches one of these common needs: Roll 1d6, 2d6, d20, percentile-style dice, or custom sided dice. Add a positive or negative modifier for tabletop game checks. It works best when you already know the values, dates, units, or settings the page asks for.

What is the Dice Roller doing with my inputs?

In plain language: The roller generates each die as a random whole number from 1 through the number of sides, adds the rolls together, then applies the modifier. The examples on the page are there so you can compare your inputs with a filled-out calculation before copying the answer.

What should I double-check before trusting the answer?

Use it for everyday games, teaching, and quick picks. Do not use it for gambling, legal drawings, security, or audited randomness. Also check that you used the right unit, date, scale, or mode because small input changes can change the result.

Does the site save what I enter?

No. The calculator runs in your browser tab. Your recent answers stay only on the page while you use it, and they are not sent to a server.
