How to Use the Online Dice Roller and Types of Dice
This dice roller lets you roll 3D dice, rendered with three.js, right in your browser. Pick a dice type (D4, D6, D8, D10, D12, D20 or D100) and how many to roll (up to 10), then press Roll: the polyhedral dice tumble in 3D and settle with the rolled face pointing up. When you roll several dice, the total is calculated automatically and recent results are kept in the history.
D6 is the standard six-sided die used for board games and family games. D20 (the twenty-sided die), along with D4, D8 and D12, is used for checks in tabletop RPGs such as Dungeons & Dragons (D&D), while D100 gives a percentile roll (1–100) used in games like Call of Cthulhu. Switch dice to match the situation and roll as many as you need at once.
Each result is determined by Math.random pseudo-random numbers, so every face has an equal probability. Everything runs entirely in your browser and no results are ever sent to a server. No app install or sign-up is required, and it works on both phones and computers.

- Seven types: D4, D6, D8, D10, D12, D20 and D100. It covers the polyhedral dice commonly used in tabletop RPGs.
- Can I roll multiple dice at once?
- Yes. You can roll from 1 to 10 dice at the same time. When you roll two or more, the total of all results is shown automatically — for example 2D6 (two six-sided dice).
- Are the results random and fair?
- The roller uses the browser's Math.random pseudo-random generator so that each face has an equal probability. Statistically, every value comes up with the same likelihood.
- Can I use it for TRPGs and D&D?
- Yes. It supports D20 and D4–D12 polyhedral dice, so you can use it for checks in Dungeons & Dragons and other games. D100 works for percentile rolls in games like Call of Cthulhu.
- How do I roll a D100?
- Select D100 as the dice type and a single roll gives you a value from 1 to 100 — handy for percentile checks.
- Do I need to install anything? Is my data sent anywhere?
- No install is required — it runs entirely in the browser. All processing happens on your device and no data, including your rolls, is sent to any external server.
