Understanding Dice Notation

Dice notation is a standard way to describe dice rolls:

• 1d6 = Roll 1 six-sided die
• 2d8 = Roll 2 eight-sided dice and add them together
• 4d6 = Roll 4 six-sided dice (common in D&D for ability scores)
• 1d20+5 = Roll 1 twenty-sided die and add 5
• 3d8-2 = Roll 3 eight-sided dice, subtract 2

Fairness & Randomness

This dice roller uses JavaScript's Math.random() function for generating random numbers. While not cryptographically secure, it's perfectly fair for gaming purposes. Every number from 1 to the die's maximum has an equal probability of being rolled.

To verify fairness, try rolling a large number of dice (100+) and observe that the distribution approaches theoretical expectations. For example, rolling 1000d6 should average around 3500 (1000 × 3.5).
