Free online virtual dice roller with realistic 3D animations! Roll up to 100 dice at once, up to 20 sides, unlimited rolls, and custom themes.
Get unlimited rolls and instant results with our free online virtual dice roller. Roll a die 1-6 for board games, grab two dice for Monopoly night, or go full D&D with a d20. Perfect for any tabletop game that requires dice.
Our free online dice roller harnesses your browser’s random number generator to deliver fast, unbiased results. Ideal for tabletop role‑playing games, board games, classroom probability lessons, and decision-making, this virtual dice simulator supports up to 100 dice with customizable sides, themes, and sizes, with no downloads, ads, or signups required.
Use our dice roller as an educational tool to explore fundamental concepts in probability theory, statistics, and game design.
Each face of a fair die has an equal probability of appearing. For a standard 6-sided die, each number (1-6) has a 1/6 chance (~16.67%).
Formula: For a die with n sides, each face has probability = 1/n. For a 6-sided die: 1/6 ≈ 16.67%
As you roll more dice, the actual distribution of outcomes will converge closer to the theoretical probability of each face appearing equally.
Try it: Roll 10 dice, then 100, then 1,000. Notice how the percentages get closer to 16.67% for each number with larger sample sizes.
Each dice roll is completely independent. Previous rolls have zero influence on future outcomes - the die has no memory!
Important: Even after rolling three 6s in a row, the next roll still has exactly a 1/6 chance of being any number.
When rolling multiple dice, certain sums are more likely than others. The probability distribution forms a bell curve (normal distribution).
Example: With two 6-sided dice, rolling a 7 is most common (1+6, 2+5, 3+4, 4+3, 5+2, 6+1 = 6 ways), while rolling a 2 or 12 is rare (only 1 way each).
The expected value (average) of a fair 6-sided die is 3.5. For multiple dice, multiply by the number of dice rolled.
Calculation: Expected value = (1+2+3+4+5+6)/6 = 3.5. For 3 dice: 3 × 3.5 = 10.5 average sum.
Our roller supports 4, 6, 8, 10, 12, and 20-sided dice. Each has different probability distributions and expected values.
Popular in: Tabletop RPGs like D&D use various dice (d4, d6, d8, d10, d12, d20) for different game mechanics and damage calculations.
Understand game balance, damage calculations, and randomness mechanics in board games, RPGs, and video games.
Perfect for classroom demonstrations of discrete probability, expected value, variance, and statistical distributions.
Generate random discrete outcomes for simulations, Monte Carlo methods, and statistical experiments with controllable parameters.
Explore concepts like frequency distribution, chi-square tests, and hypothesis testing using intuitive dice roll data.
Set the side count in the customize panel and this roller becomes any die in your bag. Here is what each standard die is for, whether you are rolling one d20 or a fistful of d6s.
The smallest standard die. In D&D it covers light weapon damage like daggers and darts, and healing effects such as cure wounds at low levels.
The die everyone grew up with. Two of them run Monopoly, backgammon, and Catan; five run Yahtzee and Farkle. In tabletop RPGs it handles shortswords, fireball damage, and ability score rolls.
Two four-sided pyramids joined at the base. Common for longbows, rapiers, and other medium weapon damage in D&D and Pathfinder.
Rolled alone for 1 to 10, or in pairs as percentile dice (d100) when a game asks for a roll from 1 to 100. The backbone of many horror and World of Darkness systems.
The barbarian die. Greataxes and other heavy weapons roll a d12, and some games use it for months or hours because it maps neatly onto a clock face.
The most famous die in gaming. D&D resolves nearly everything with it: attack rolls, saving throws, and skill checks. Rolling a natural 20 is the best feeling in the hobby.
Dice are older than written history. The oldest known set, found with a backgammon-like board in the Burnt City of Shahr-e Sukhteh in Iran, is roughly 4,800 years old. Greeks and Romans rolled astragali, the ankle bones of sheep, before carved cubes took over. Roman soldiers loved dice enough that Julius Caesar reached for a dice metaphor when he crossed the Rubicon: alea iacta est, the die is cast.
The modern d6 has kept the same design for millennia: opposite faces always add up to seven. The rest of the polyhedral family (d4, d8, d12, d20) is built on the Platonic solids the ancient Greeks studied, but it took Dungeons & Dragons in 1974 to turn the d20 into an icon. Whatever you are rolling for, a fair die is one of the oldest and simplest randomizers humans have ever built, and this page gives you a whole bag of them for free.
Join thousands rolling virtual dice for games, decisions, and fun!
Yes, our dice roller is 100% free to use. There are no ads, no signups, and no limits on how many times you can roll the dice. Enjoy!
Yes. Every roll uses your browser's random number generator, so each side of the die has an exactly equal chance. The stats panel even shows expected vs actual averages so you can verify the fairness over many rolls.
Yes. Set the number of sides to roll a d4, d6, d8, d10, d12, or d20, and combine up to 100 dice in a single roll. That makes it a handy dice roller for D&D and other tabletop RPGs, whether you need one d20 attack roll or a fistful of d6 damage dice.
Open the customize panel and set the number of dice to 2 (or any amount up to 100), then roll. Each die lands independently and the results log shows both values plus the total, which is perfect for board games like Monopoly or Catan that use two 6-sided dice.
Google's built-in dice widget is handy for a single quick roll, but it does not keep history. Our virtual dice roller adds realistic 3D rolling animation, up to 100 dice at once, roll history with sums and timestamps, distribution stats, CSV export, custom themes, and saved configurations with a free account.
Absolutely! Our virtual dice roller works for any game that needs dice: D&D and other RPGs, Yahtzee, Farkle, Monopoly, backgammon, classroom math games, and more. Roll a standard die 1-6 or switch to any other side count.
You can roll up to 100 dice at once. This is perfect for games that require multiple dice rolls or simulating large competitions in tabletop games.
Yes, you can customize the dice theme to suit your preferences. Choose from a variety of themes and sizes to make your dice rolls more fun and engaging.
Yes, you can view the results log for all your dice rolls. This includes the total sum of all the dice rolls, making it easy to keep track of your results.
