Dice Roller
The D12 is the twelve-sided dodecahedron, known in D&D as the barbarian damage die (the greataxe is 1D12) and outside tabletop games for month or zodiac-random purposes. This roller gives a readable faceted 3D-style result.
Roll dice from D4 through D100.
Choose your dice, then roll.

How to Use
This page is pre-set to roll a D12. Tap the Roll button to drop one die; use the count toggle to roll up to 10 at once. Results are generated via the Web Crypto API, so every face has an exactly equal chance.
For the full dice roller with dice-type selector (D4 through D100), visit the main Dice Roller. For non-standard ranges, use the Random Number Generator.
The D6 uses an animated 3D cube with pips. D4, D8, D10, D12, and D20 are true 3D polyhedral dice with numbers on every face, thrown with a bouncing tumble before settling on the result. D100 is shown as a standard percentile pair. All animations respect prefers-reduced-motion.
About This Tool
The dice roller supports common dice shapes and multiple dice rolls for games, classroom probability lessons, and quick random outcomes. It is useful when a result should feel familiar to tabletop players or students.
Unlike a simple number generator, dice notation carries context. Rolling a d20, d6, or d100 communicates the range and expected use immediately.
Privacy Note
Dice rolls do not require user data. Results are displayed in the browser and are not tied to an account.
Limits
This is a casual dice roller, not a verified random service for gambling, paid competitions, or regulated contests.
Random tools are most helpful when the rules are clear before the result is generated. Decide what the input means, whether duplicates are allowed, and whether the first result should be final. Clear rules make the result easier to trust and explain.
For casual choices, games, classroom activities, examples, and creative prompts, a browser-based tool is usually enough. For regulated contests, high-value selections, safety decisions, legal records, or professional advice, use a process designed for that responsibility.

Frequently Asked Questions
Yes. Every face from 1 to 12 has an equal chance. Randomness comes from crypto.getRandomValues (Web Crypto API), and modulo bias is handled via rejection sampling on uint64 values.
Yes. The count toggle lets you roll up to 10 D12s. A running total is shown below the dice.
Yes, casual tabletop play is a primary use case. The rolls are cryptographically random, so they are at least as fair as physical dice. For tournament play or high-stakes games, check with your group whether virtual rolls are accepted.
The D6 uses physical pip faces, so it is animated as a cube. The other dice are true 3D polyhedra with a number on every face, plus a large result badge so the roll is easy to read, and D100 is shown as a standard percentile pair.
For casual games and classroom use, yes. It cannot replace a physical die in regulated contests or competitions, but it works well for virtual game nights, remote D&D, and classroom probability lessons.
