Roll any number of dice with 4 to 100 sides.
Random and local to your browser.
How does an online dice roller work?
Each die returns a uniform random whole number from 1 to its number of sides, and the total is the sum of all dice. Every die is independent and fair, with the total ranging from the number of dice up to dice × sides. You can roll any number of dice from D4 to D100. Rolling 2 × D6 might give 3 and 5 for a total of 8.
Understanding your result
Every die is independent and fair. The total range runs from the number of dice up to dice × sides.
Formula and method
Each die returns a uniform random whole number from 1 to its number of sides; the total is the sum of all dice.
Assumptions and limitations
The roller produces fair, independent results from your browser's random generator, fine for games and teaching but not a certified source for gambling. It rolls virtual dice with four to a hundred sides and sums them; it does not apply game-specific rules such as rerolls, modifiers, advantage or exploding dice, which you would track yourself.
Worked example
Rolling 2 × D6 might give 3 and 5 for a total of 8.

Frequently asked questions
Can I roll a D20?
Yes. Choose D20 (or up to D100) and any number of dice.
What total range can I expect from multiple dice?
The lowest possible total equals the number of dice, when every die shows one, and the highest equals the number of dice multiplied by the number of sides. So two six-sided dice range from 2 to 12. Middle totals are more likely than the extremes because more combinations produce them.
Does it apply modifiers or special dice rules?
No. The roller returns a fair result for each die and adds them into a total. It does not handle house rules such as rerolls, bonuses, advantage or exploding dice. You apply those yourself, using the raw numbers the tool provides as your starting point for any game system.
