Someone forgot the Monopoly die or the roleplaying session needs a d20 and the dice are at a friend's house. On a video call, everyone also needs to see the same roll without anyone saying "I got a 6".
How to use Dice Roller step by step
1. Choose the sides
d6 is the classic die; d20 is the roleplaying one; d100 is for percentages. d4, d8, d10 and d12 are there too.
2. Set how many dice
From 1 to 10 at once. With several, you will see the total.
3. Press "Roll dice"
The dice shake for a moment and show the result; the history of your latest rolls stays below.

An online die for board games, roleplaying and quick decisions
The six-sided die is the one from every classic board game, but roleplaying games use a whole set: d4, d6, d8, d10, d12 and the famous d20. Here you have them all, up to ten at once, with no need to hunt around the house or worry about one rolling off the table.
Every face has the same probability because the result comes from the browser's cryptographic randomness. And with several dice the total is not uniform: with two six-sided dice, 7 is the most frequent result (6 of 36 combinations, 16.7%), while 2 and 12 each come up only once in 36.
Dice included
- •d4, d6, d8, d10 and d12 for board and roleplaying games.
- •d20 for skill checks and attacks.
- •d100 for percentages and random tables.
- •1 to 10 dice per roll, with total and a history of the last 8.

Frequently Asked Questions
Is the online die fair?
Yes. It uses the browser's cryptographic generator and every face has the same probability. There is no server and no way to influence the result.
What is a d20?
A 20-sided die, typical of roleplaying games like Dungeons & Dragons for attack and skill rolls.
What is the most likely total with two dice?
7: 6 of the 36 combinations (16.7%). 2 and 12 are the least likely, 1 in 36 (2.8%).

What I would do if I were in your shoes
«In our online roleplaying sessions, rolling on a shared screen settled 100% of the arguments. What matters about a die is that everyone sees the roll at the same time.» — DataKorex Engineering Team
