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 measurements, amounts, units, or options 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 example before copying the answer.

What do the main Dice Roller inputs mean?

The main inputs are the measurements, amounts, units, or options the tool needs before it can work. Read each field label, keep units consistent, and compare your entry with the examples if the answer looks strange.

How should I read the Dice Roller answer?

Read the headline answer, then check the smaller lines beside it. For everyday tools, those lines usually show the distance, time, cost, units, or setting that made the answer change.

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 the unit, scale, mode, and result limit because small input changes can change the answer.

Does the site save what I enter?

No. The tool 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.
