Select Your Dice Type
Choose from standard dice types including D4, D6, D8, D10, D12, D20, and D100 (percentile). Each die has the appropriate number of sides and follows standard tabletop gaming conventions.Set Number of Dice
Specify how many dice you want to roll at once. Roll a single die or multiple dice of the same type simultaneously—perfect for rolling damage, ability checks, or any game requiring multiple dice.Add Modifiers (Optional)
Apply positive or negative modifiers to your roll total. This feature is especially useful for tabletop RPGs where you often add ability modifiers, proficiency bonuses, or situational adjustments to your dice rolls.Roll the Dice
Click the 'Roll' button to generate your random results. Each die is rolled using a cryptographically secure random number generator to ensure fair and truly random outcomes.View Results and Statistics
See your roll results displayed both individually and as a total sum. For multiple dice, you'll see each individual die result plus the combined total with any modifiers applied.
Tips & Tricks
Use Dice Combinations
Combine different dice types for complex rolls by making multiple rolls. For example, roll 2d8 + 1d6 by first rolling the d8s, then the d6, and adding the results—perfect for calculating varied damage in RPGs.
Save Time in Games
During intense gaming sessions, use the dice roller to speed up play. Rolling all damage dice at once or quickly determining multiple outcomes saves valuable game time.
Advantage/Disadvantage Rolls
For D&D 5e advantage or disadvantage, roll two D20s and take the higher or lower result respectively. You can track both rolls simultaneously to see the difference.
Percentile Dice
Need a number from 1 to 100? Use the d100 dice roller, which explains how percentile dice work and the odds of rolling under a number.
Create Custom Probability Distributions
Combine different dice types and modifiers to create custom probability distributions for unique game mechanics or statistical demonstrations.
Track Critical Results
Keep an eye out for natural 20s (critical hits) or natural 1s (critical fails) when rolling D20s for added excitement in your games.
Use for Learning Probability
The dice roller makes an excellent educational tool for teaching probability concepts. Demonstrate how results distribute across multiple rolls of different dice types.
Frequently Asked Questions
Are the dice rolls truly random?
Yes. Every die is rolled with your browser's cryptographic random number generator (crypto.getRandomValues) using an unbiased method, so each face is equally likely. Unlike physical dice, there are no manufacturing defects or worn edges that could bias the result.
What dice types are available?
We offer all standard tabletop gaming dice: D4 (four-sided), D6 (six-sided), D8 (eight-sided), D10 (ten-sided), D12 (twelve-sided), D20 (twenty-sided), and D100 (percentile/hundred-sided, typically represented by two D10s).
Can I roll multiple dice at once?
Yes. The dice roller above lets you add several dice types and roll up to 20 dice of each type at once. The notation roller lets you type an expression such as 8d6 or 1d8+1d4+2 (up to 100 dice per term), which is handy for large damage rolls.
How do modifiers work?
A modifier is added to or subtracted from the total, not to individual dice, and it is applied once per roll. For example, 3d6 with a +5 modifier rolls three six-sided dice, sums them, and adds 5. In the notation roller, write it directly: 3d6+5.
Can I use this for Dungeons & Dragons and other RPGs?
Yes. It supports the standard RPG dice (D4 to D100) and modifiers, and the notation roller understands expressions like 1d20+5 for an attack roll or 8d6 for a fireball. It works for D&D, Pathfinder, Call of Cthulhu and most other tabletop systems. It does not implement rules such as advantage, exploding dice or keep-highest.
How do I roll percentile dice (D100)?
Select the D100 option from the dice type dropdown, or type d100 in the notation roller. It produces a single number from 1 to 100 with equal chance for each value, which is the same result as rolling percentile dice.
Does the dice roller keep a history of my rolls?
Yes, the dice roller maintains a history of your recent rolls during your session, allowing you to reference previous results. This history is only stored locally in your browser and resets when you clear your browser data.
What is dice notation like 2d6+3?
It is the standard shorthand for a roll: the first number is how many dice, the number after the d is how many sides each has, and +3 is a flat bonus. So 2d6+3 means roll two six-sided dice, add them, then add 3. The result is between 5 and 15, with an average of 10.
What are the odds when rolling two six-sided dice?
With 2d6 there are 36 equally likely outcomes. A total of 7 is the most common at 6 in 36 (16.67%), while 2 and 12 each come up only 1 in 36 (2.78%). Type any expression into the notation roller to see its exact odds table (for up to 10 dice with 100 sides or fewer).
