About this tool

This dice roller rolls virtual dice for board games, tabletop role-playing, and any moment you need a fair, unpredictable number. Choose one of the seven standard polyhedral dice, from the four-sided d4 up to the hundred-sided d100, set how many to roll, and add an optional modifier. The result appears the instant the page loads and refreshes every time you press Roll, showing each individual die, the subtotal of the dice, and the final total.

It reads and writes the notation tabletop players already use. Rolling three eight-sided dice with a plus two bonus is written 3d8 + 2, and the tool shows that label next to the total so a result is easy to record or read aloud. Modifiers can be negative for penalties, the die count runs up to 100 at a time, and a short history keeps your recent rolls in view so you can compare an attack roll against a saving throw without reaching for pen and paper.

Each face has exactly the same chance on every roll, drawn from your device's secure random source rather than a predictable pattern, so no number is favored over the run of a long game. Nothing is uploaded and no roll is logged. If you need plain random integers over a custom range instead of standard dice, the random number generator covers that, and the password generator uses the same quality of randomness to build strong passwords.

Frequently asked questions

Which dice can I roll?
You can roll the seven standard polyhedral dice used in most games: d4, d6, d8, d10, d12, d20, and d100. Pick one type per roll, choose how many of that die to roll together, from a single die up to 100 at once, and add an optional modifier.
How do modifiers and totals work?
A modifier is a fixed number added to or subtracted from the sum of the dice, written like 2d6 + 3 or 1d20 - 1. The tool shows the subtotal of the dice on their own and the final total after the modifier, so both the raw roll and the adjusted result are clear.
Are the rolls actually fair and random?
Yes. Each die is drawn from your browser's secure random source, and the tool is built so every face is equally likely on each roll, with no bias toward high or low numbers. Past rolls have no effect on the next one, exactly like physical dice.
Does it keep a history of my rolls?
Yes. Your most recent rolls stay listed with their notation and total while the page is open, so you can compare outcomes at a glance. The history lives only in this browser tab and clears when you close or reload the page.
Is my data uploaded anywhere?
No. Everything runs in your browser; nothing is sent to a server. Rolls and history stay on your device and are never uploaded or logged.
