Dice Roller
e.g. 2d6+3, d20, 4d6-1
Rolled in your browser with a cryptographic random source, never sent to a server.
What is Dice Roller
This dice roller lets you roll any standard die (d4, d6, d8, d10, d12, d20, d100) with one tap, or type full dice notation such as 2d6+3 to roll several dice and add a modifier at once. Each roll uses your browser's cryptographic random source, so the results are fair and never touch a server.
How to use
- Tap a quick die (d20, d6, and so on) to roll it right away.
- Or type notation like 2d6+3 or 4d6-1 in the field.
- Press Roll (or Enter) to see the total and every individual die.
- Copy the result if you want to paste it into a chat or character sheet.
When to use it
In the middle of a D&D fight and need to roll an attack? Type 1d20+5, press Enter, and you see the die and the total at once. It also covers a quick 2d6 for board games, a d100 for random tables, or 4d6 when rolling up new character stats.
Frequently asked questions
What dice notation is supported?
Standard notation like NdS with an optional modifier: 2d6, d20, 4d6+3, 1d8-1, even multiple groups such as 2d6+1d4+2. The count goes up to 100 and the sides up to 1000.
Are the rolls really random?
Yes. Each die uses the Web Crypto API (crypto.getRandomValues), the same cryptographically secure source browsers use for encryption keys, not a predictable pseudo-random formula.
What does the d in d20 mean?
The d stands for die, and the number is how many sides it has. So d20 is a twenty-sided die, and 2d6 means roll two six-sided dice.
Can I roll several dice at once?
Yes. Set a count before the d (for example 4d6) to roll that many, and add a modifier with + or - to adjust the total. Every individual result is shown alongside the sum.
Can I add this dice roller to my own website for free?
Yes, for free. Open 'Embed this tool' just below the roller, copy the iframe code and paste it into your page. The widget is self-contained and needs no install. Add ?theme=dark or ?theme=light to the embed URL to match your site.
