How the Dice Roller works

Select the type of dice you want to roll, such as D6, D20, or D100, and choose how many dice to roll at once. You can easily adjust the settings to match your specific game or activity.

Process Your Data
Each die draws one fresh random integer between 1 and its side count. Multi-dice runs also add everything up, so you get both the individual rolls and the total.

Dice Roller FAQ
Is an account required to use this tool?
No, you can use this tool instantly without registering or logging in.
Is my data secure and private?
Yes, all processing happens directly in your browser, meaning your data is never sent to our servers.
Does the tool work offline?
Once the page is loaded, the core random generation engine works entirely offline in your browser.
Is there a character or file size limit?
Yes: each roll uses between 1 and 20 dice, and the die selector covers d4, d6, d8, d10, d12, d20, and d100.
What number range does each die produce?
Whole numbers from 1 up to the side count, inclusive. Nothing starts at zero, so a d100 can roll any value from 1 to 100.
Can I reproduce a previous roll?
No. Each click makes fresh independent draws with no seed, so earlier sequences cannot be recalled.
What is the technical working principle?
Each die draws one uniform random integer from 1 to its side count, and multi-dice runs add them into a total.
What is the most common use case?
Gamers and teachers most commonly use it to resolve random mechanics and demonstrate probability concepts.
Does the roller handle game modifiers or advantage?
No. The output is raw dice only, so apply your game's modifiers, advantage rules, or rerolls yourself afterward.
