Understanding Virtual Dice Rolling
How It Works
This virtual dice roller uses a pseudorandom number generator to simulate physical dice rolls. Each die generates a random integer between 1 and the number of sides on that particular die.
Fairness and Randomness
- •Each outcome has equal probability
- •No bias toward any particular number
- •Statistically equivalent to physical dice
- •Independent rolls with no memory

Cube with 6 faces, opposite sides add to 7. Most common in board games.
RPG Dice (d4-d20)
Platonic solids used in role-playing games for different probability distributions.
