Dice Roller Guide: One Die, 2 to 100 Faces
A virtual die is perfect for a saving throw, a missing board-game piece, or a quick random order. It keeps no history, has no witnesses, and should not settle anything valuable.
When a die is missing
A tabletop session needs a twenty-sided die, a board game lost a piece, the group needs a random order, or you want an integer between 1 and 100 right now. Opening a page is faster than hunting through the box.
Prototyping benefits too: adding a little randomness to demo data, assigning an order, or simulating a single check. The output is one integer, easy to paste into a sheet or a script.
- A stand-in die for tabletop and board games
- Randomising order or who goes first
- Adding a random value to demo data
Faces and range
The default is six faces, configurable from 2 to 100, and the result is an integer from 1 through the face count, inclusive. Twenty faces is a twenty-sided die, a hundred is a percentile die; no formula required.
The value comes from the browser's cryptographic random source and is mapped by modulo. When the face count does not divide the random range evenly, a tiny bias exists — irrelevant for tabletop play, but worth avoiding in statistical simulation, where an unbiased library is the right tool.
- Default six faces, configurable from 2 to 100
- Result includes both 1 and the maximum
- One die per roll; roll again and add for multiple dice
Boundary: no history, no review
Nothing is stored. Refresh and the result is gone, and there is no seed to reproduce it. That makes the roll impossible to verify afterwards, which is fine for fun and awkward when something is at stake.
It also lacks the social proof of a physical die: everyone at the table sees where it lands, while a virtual roll exists on one screen. Where trust matters, use a public, verifiable source instead.
- No history; refresh clears the result
- No seed, so a roll cannot be reproduced
- One screen only, so trust is weaker than a physical die
FAQ
Can I roll multiple dice at once?
No, one die per roll. For three six-sided dice, roll three times and add the results, or note each roll. The tool keeps no history, so record them yourself.
Is the result fair?
Fair enough for play: the value comes from the browser's cryptographic source and maps to 1 through the face count. Face counts that do not divide the range evenly introduce a negligible bias.
How many faces are supported?
From 2 to 100. Two behaves like a coin, 20 gives a twenty-sided die, and 100 is the usual percentile die. Outside that range, use the random number tool instead.
