Quick start
- Enter how many dice you want to roll.
- Enter the number of sides per die.
- Add a modifier only when the game or example calls for one.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Roll 1d6, 2d6, d20, percentile-style dice, or custom sided dice.
- Add a positive or negative modifier for tabletop game checks.
- Show each die roll and the final total.
- Keep recent rolls while comparing examples.
What this tool helps with
The Dice Roller is for quick, casual random rolls. It shows every die, the subtotal, the modifier, and the final total so the result is easy to check.
Match each input label on the tool to the text, format, mode, option, or platform rule you actually need.
The logic in plain language
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.
The example cards on the tool page show a complete input and the kind of answer you should expect.
How to read the answer
Read the main result first. Then check the smaller lines for the totals, units, ranges, counts, or formula steps behind it.
- The main answer is the final total after the modifier.
- Rolls shows the individual die results.
- Subtotal is the dice total before the modifier.
Common mistakes to avoid
If the answer looks strange, the most likely cause is a small input mismatch: the wrong text, mode, format, line break, privacy choice, or platform rule.
- Do not use this for gambling, official drawings, or audited random selection.
- Check whether your game needs one die, multiple dice, or a modifier.
- Remember that random rolls can repeat and do not balance out in short runs.

This guide follows the inputs, logic note, and examples on the tool page. If your platform, class, or workplace has an official rule, use that rule first.
