What is an online dice roller?
Rolling dice is the most classic way to bring chance into a game or a decision. A six-sided die gives a result from 1 to 6 with equal probability for each number. This tool lets you roll virtual dice from your phone or computer, with no physical dice needed and none lost under the couch.
It is perfect when you are playing a board game and missing a die, when you need several at once, or when you just want a quick, visual random number with a real rolling animation.
When to use the dice roller?
- Board and role-playing games when a die is lost or broken.
- Deciding turns: roll higher and you go first.
- Quick draws among a few people by assigning each a number.
- Learning activities to teach probability and statistics.
How does our dice roller work?
Each roll generates a pseudo-random number with the browser’s Math.random() function and turns it into a die face. Every face is equally likely, just like a balanced physical die, and each roll is independent of the last.
The rolling animation is just for show: the result is decided the moment you roll. Everything is computed in your browser, with nothing sent to a server.
Types of dice and what each is for
Although the six-sided die (the D6) is the best known, board games and especially role-playing games use many more: the D4, D8, D10, D12 and the famous D20 from Dungeons & Dragons, plus the D100 for percentages. Each one simply changes the range of possible numbers, but the idea is the same: every face has the same probability. With several dice at once you can add up rolls (for example, 2D6 to move in a board game) or throw a handful for RPG systems that ask you to "roll 3D6". Having a roller on your phone is super handy when you're missing exactly the die you need, or when several of you are playing and there aren't enough to go around.
Frequently asked questions
Are the dice balanced?
Yes. Every face is equally likely, generated by the browser’s pseudo-random engine with no bias.
Can I roll several dice at once?
Yes, the tool lets you roll multiple dice in a single throw for games that need it.
Is it valid for official draws with money at stake?
It is great for casual use, but it is not cryptographically secure, so avoid it for draws with legal or financial value.
Why do repeated numbers come up in a row?
It is normal: each roll is independent, so repeats happen often in any game of chance.
What do D6, D20 and so on mean?
The "D" stands for "die" and the number tells you how many faces it has: a D6 is the normal six-sided die, a D20 has twenty faces and is widely used in RPGs, and a D100 gives a number from 1 to 100. They all work the same way: they spread the probability evenly across their faces.
Can I add up the result of several dice?
Yes. When you roll several dice at once you can add their values, just like the board games that ask for rolls such as 2D6 or 3D6. The tool shows each die so you can total them up at a glance.
