What Is a Dice Roller?

How It Works
Our dice roller creates a fresh random number every time you click Roll. Choose which dice you want, pick how many, and see your result right away. Each roll is completely independent, so previous rolls don't influence what you get. It's a quick and easy way to roll virtual dice for board games, classroom activities, probability exercises, or whenever you need a random result. This tool uses a pseudo-random number generator (PRNG) — the same logic trusted by digital gaming platforms worldwide.
Formula Used
Our dice roller picks a random number between 1 and whatever's on your die. Roll a 6-sided die (D6)? You'll get anything from 1 to 6. Roll a 20-sided die (D20)? You'll get 1 to 20. Each roll is completely independent — every result is fresh and random.
Example Table
| Dice Type | Possible Result Range | Example Result |

| D4 | 1-4 | 3 |
| D6 | 1-6 | 5 |
| D8 | 1-8 | 2 |
| D10 | 1-10 | 7 |
| D12 | 1-12 | 11 |
