Custom Dice Roller
About this tool
Need a die that doesn't exist in the box? The custom dice roller lets you set any number of sides — a d3, a d7, a d50, even a d1000 — and roll one or many at once. It's a free online roller, so there's nothing to buy, 3D-print or build — perfect for unusual board games and homebrew rules.
How to use it

- Choose how many dice to roll.
- Tap Roll for instant results and a total.
- Change the sides any time and roll again.
Frequently asked questions
- Is this a physical die or an online roller?
- It's a free online roller — you set the number of sides and it spins up a virtual die, so there's nothing to buy, print or build.
- What sides can I create?
- Anything from a d2 up to a d1000, including odd ones like a d3, d7 or d50 that don't come in a normal dice set.
- What's the maximum number of sides?
- You can set anything from 2 up to 1000 sides per die.

- Is it free and private?
- Completely free, no sign-up. Everything runs in your browser, so nothing you type is uploaded.
