Where Can You Use an Online Dice Roller?
An online dice roller can be used in many situations where random results are needed. It works well for games, learning activities and quick decisions.

How Random Are the Dice Results?
This Dice Roller uses browser-based random number generation to create a result within the selected dice range. For example, a D6 gives a result from 1 to 6, while a D20 gives a result from 1 to 20.
Each roll is generated separately. Previous results do not control the next result. This makes the tool useful for casual games, practice and learning.
Dice Probability Basics
With one fair six-sided die, each number from 1 to 6 has the same chance of appearing. The probability of rolling any one number is 1 out of 6, or about 16.67%.
With two six-sided dice, there are 36 possible combinations. Some totals are more common than others. For example, a total of 7 can happen in more ways than a total of 2 or 12.
| S.No | Dice Event | Probability |
|---|---|---|
| 1 | Rolling a specific number on one D6 | 1 in 6, or 16.67% |
| 2 | Rolling double sixes with two D6 dice | 1 in 36, or 2.78% |
| 3 | Rolling a specific number on one D20 | 1 in 20, or 5% |
| 4 | Rolling a specific number on one D100 | 1 in 100, or 1% |
