A virtual dice roller is a simple online tool that simulates rolling physical dice. You tell it how many dice to roll and how many sides each die has. Then it gives you random results.
Think of it like shaking a cup of dice and throwing them on a table. Except the table is your screen, and the dice never roll off the edge.
Our virtual dice roller can handle all kinds of dice:
d6
Standard 6-sided
d20
20-sided for D&D
d4/d8/d10/d12
Classic RPG dice
Custom
Any number of sides
Here's the thing that most people don't know. When you click "Roll," your computer doesn't actually "throw" anything. Instead, it uses something called a random number generator (RNG for short).
An RNG is like a super-fast coin flipper inside your computer. It generates a number between 1 and the number of sides on your die. And it does this in a way that's completely unpredictable.
I get this question a lot. Good dice rollers use a cryptographically secure random number generator. That's a fancy way of saying it's as random as flipping a real coin or rolling a real die. In fact, it's even more random than physical dice, because real dice can have tiny imperfections that make them slightly biased. So no, our dice roller isn't out to get you. The dice just hate everyone equally.
This is the biggest group. When you're playing D&D online with friends across the country, you can't exactly pass around a real die. A virtual dice roller is the next best thing. Plus, you can roll 10 dice at once for that fireball spell without picking them all up off the floor.
Math teachers love dice rollers for teaching probability. Instead of having 30 kids each rolling real dice (and losing them under desks), everyone can use the same online tool. It's cleaner, faster, and you can see the results instantly.
Lost the dice from Monopoly? No problem. Just pull up our dice roller on your phone. Same for any board game that needs dice.
Can't decide where to eat? Roll a die. Heads or tails? Roll a die. Need to pick a random student to answer a question? Roll a die. It's a simple way to make fair choices.
Using our dice roller is about as simple as it gets. Here's the step-by-step:
Choose how many dice you want to roll. You can pick anywhere from 1 to 100.
Pick the number of sides on each die. Common choices are 6, 10, 20, but you can type any number.
Click "Roll" and watch the magic happen.
See your results instantly. The total and each individual die result are shown.
That's it. No sign-up, no ads, no nonsense.
When you roll multiple dice, the results are shown separately. So if you roll 3d6 (three six-sided dice), you'll see something like "4, 2, 6" and a total of "12." This is super helpful for games where you need to know each individual roll, not just the sum.
Your character casts a fireball spell. That's 8d6 damage. Instead of rolling eight physical dice one by one, you just set our roller to 8 dice with 6 sides each. Click once, and you get your damage total. Easy.
A teacher wants to show students why 7 is the most common sum when rolling two dice. They roll 100 times using our dice roller and record the results. The class sees that 7 comes up way more often than 2 or 12. That's probability in action.
You and your friend can't agree on a movie. Assign each movie a number (1-6), then roll one die. Whatever number comes up, that's the movie you watch. No arguments, no hard feelings.
🎲 Real Dice Are Better For:
💻 Virtual Dice Are Better For:
Honestly, both have their place. I use real dice when I'm playing in person and virtual dice when I'm online or need to roll a ton of them at once.
Mistake 1: Forgetting to Set the Number of Sides
This is the big one. If you're playing D&D and need a d20, but the roller is set to d6, you're going to get very different results. Always double-check the number of sides before you roll.
Mistake 2: Rolling Too Many Dice
Our roller can handle up to 100 dice at once. But do you really need that many? For most games, 1-10 dice is plenty. Rolling 100 dice just gives you a wall of numbers that's hard to read.
Mistake 3: Not Using the History Feature
Some dice rollers (including ours) let you see your roll history. This is super useful if you need to prove what you rolled or if you want to analyze patterns. Don't forget to use it.
Use Dice Rollers for Random Number Generation. Need a random number between 1 and 100? Just set the dice roller to 1 die with 100 sides. Boom, instant random number generator.
Combine Multiple Rolls. Some games need different dice types at once. For example, in D&D, roll a d20 for an attack and a d8 for damage — just do two separate rolls.
Teach Probability with Large Samples. Have students predict how many times each number comes up when rolling a d6 100 times. Then actually do it. Results will be close to 16-17 per number. That's the law of large numbers.
Did you know that dice have been around for thousands of years? The oldest known dice were found in Iran and date back to around 3000 BC. They were made from bone or ivory.
Ancient Romans loved dice games so much that they had laws against gambling with them. Sound familiar?
And here's something wild: the opposite sides of a standard die always add up to 7. So 1 is opposite 6, 2 is opposite 5, and 3 is opposite 4. This design has been used for centuries to make dice as fair as possible.
Problem: The dice aren't showing up on screen.
Solution: Try refreshing the page. If that doesn't work, clear your browser cache.
Problem: The roller is slow.
Solution: Close other tabs or apps that might be using your computer's resources. Also, try rolling fewer dice at once.
Problem: I keep getting the same numbers.
Solution: This is just bad luck, not a bug. Randomness means streaks can happen. Try rolling more times to see the numbers even out.
Problem: The roller doesn't work on my phone.
Solution: Make sure your browser is up to date. Our dice roller works on all modern browsers, including Chrome, Safari, and Firefox on mobile.

So whether you're a D&D dungeon master, a math teacher, or just someone who needs to make a fair decision, our dice roller has your back. Go ahead, give it a try. Roll the dice and see what happens.
Yes, absolutely. Our dice roller uses a cryptographically secure random number generator. That's the same technology banks use for security. It's as random as rolling a physical die, if not more so.
You sure can. Just set the number of sides to 20 and click roll. You can also roll multiple d20s at once if you need to. It's perfect for D&D, Pathfinder, or any other tabletop RPG.
Use the slider or number input to choose how many dice you want to roll. You can roll anywhere from 1 to 100 dice at the same time. The results will show each die individually plus the total.
That's just how randomness works sometimes. It's like flipping a coin and getting heads five times in a row. It's unlikely but not impossible. Keep rolling and the numbers will even out over time.
Yes, it works on any device with a modern web browser. Phones, tablets, laptops, desktops — they all work. Just open the page and start rolling.
A d6 is a six-sided die (like in Monopoly or Yahtzee). A d20 is a twenty-sided die (used in D&D). The number after the "d" tells you how many sides the die has. More sides means more possible outcomes.
Roll the dice many times (like 100 or 1000) and record the results. You'll see that some numbers come up more often than others. For example, with two dice, 7 is the most common sum. This shows probability in a hands-on way.
Absolutely. Lost the dice from Monopoly, Sorry, or any other board game? Just use our dice roller. It works for any game that needs standard six-sided dice.
You can roll up to 100 dice at once with our roller. That's more than enough for any game — including a D&D wizard's meteor swarm spell. For probability experiments, you can do multiple batches of 100.
Yes, our dice roller includes a roll history feature. You can see your previous rolls to verify results, track patterns, or prove what you rolled to your gaming group.
In many cases, yes. Physical dice can have manufacturing imperfections — air bubbles, uneven edges — that favor certain numbers. Virtual dice use cryptographic algorithms that are mathematically fair and unbiased.
The oldest known dice date back to around 3000 BC, found in Iran. They were made from bone and ivory. Humans have been rolling dice for over 5,000 years — and now you can do it digitally in seconds.
