Roll a Dice
Roll 1, 2, or 3 virtual dice with realistic 3D animation. Perfect for board games, RPGs, and decision making.
Roll Distribution (1 die)
Your session - Each face should approach ~16.7%
How to Roll the Dice
Select how many dice you want to roll (1, 2, or 3), then click the Roll button or press the dice. Each die animates with a full 3D rotation before revealing the result. When rolling multiple dice, the total sum is shown prominently. Visit the Chance Games hub to explore all our randomness tools.
Dice rolling is at the heart of countless tabletop games - From Monopoly to Dungeons & Dragons. If you need to assign random numbers rather than dice faces, our random number generators let you pick any range. For random team assignments, try our group generators.
Probability Tables
A standard six-sided die (d6) has a 1-in-6 (~16.7%) chance for each face. When rolling two dice, the distribution of sums follows a triangular pattern - 7 is the most common result (6 ways out of 36 = 16.7%), while 2 and 12 are the rarest (1 way each = 2.8%). This is why 7 is so important in craps and many board games.
With three dice, the sum ranges from 3 to 18, peaking at 10 and 11 (each with 27 out of 216 possible combinations). The distribution becomes increasingly bell-shaped as you add dice - A beautiful demonstration of the Central Limit Theorem in action.

Fun Facts About Dice
- The oldest known dice were found in Iran and date back over 5,000 years.
- Opposite faces of a standard die always sum to 7 (1–6, 2–5, 3–4).
- The probability of rolling a "Yahtzee" (five of a kind in five dice) is 6/6^5 = 0.077%.
- Casino dice are precision-machined to tolerances of 1/10,000th of an inch.
- D&D uses 7 types of dice: d4, d6, d8, d10, d12, d20, and percentile d100.
- Our interval timer and stopwatch are great for timed games with dice.
Probability & Fairness
Each face of a fair six-sided die has a 1/6 probability (approximately 16.7%) of landing face-up on any given roll. Because each roll is an independent event, previous outcomes have no effect on future results - Rolling a 6 three times in a row does not change the odds on the next roll.
When rolling two dice, the 36 possible combinations produce sums between 2 and 12, but not with equal probability. The sum 7 is the most likely, achievable in 6 ways (1+6, 2+5, 3+4, 4+3, 5+2, 6+1), giving it a 16.7% chance. The sums 2 and 12 are least likely, each achievable in only 1 way (1+1 and 6+6), giving them just a 2.8% chance each. This triangular distribution is why 7 is so pivotal in games like craps and Backgammon.
Use Cases for the Dice Roller
Dice are central to board games like Monopoly, Risk, and Backgammon, where they introduce controlled randomness and keep outcomes uncertain. In tabletop role-playing games such as Dungeons and Dragons, players use a variety of multi-sided dice (d4, d6, d8, d10, d12, and d20) to resolve actions and combat. This virtual six-sided dice roller covers the majority of standard board game needs. It is also useful in classrooms for hands-on probability experiments, letting students observe how the distribution of rolls approaches the theoretical values over many trials.
Frequently Asked Questions
What is the probability of rolling a 6?
On a fair six-sided die, each face has a 1 in 6 probability of landing face-up, which equals approximately 16.7%. Every roll is independent, so rolling a 6 never becomes more or less likely based on previous results.
Why is 7 the most common sum with two dice?
When rolling two six-sided dice, there are 36 equally likely combinations. The sum 7 can be made in 6 ways: 1+6, 2+5, 3+4, 4+3, 5+2, and 6+1. No other sum has as many combinations, giving 7 a 6/36 = 16.7% probability - The highest of any two-dice sum.
What is a loaded dice?
A loaded die is weighted so that certain faces are more likely to land face-up than others. One classic method to detect a loaded die is to float it in a saturated salt-water solution - A fair die will settle randomly on different faces, while a loaded die tends to stop with the same face up repeatedly.
Is this dice roller random?
Yes. Each die result uses the browser's built-in Math.random() function, which is a statistically fair pseudo-random number generator seeded by the system. The distribution approaches equal probability for all faces over many rolls, as shown by the in-session chart.
