How to Calculate Dice Roller
What is Dice Roller?
A dice roller simulates rolling one or more dice with any number of sides — standard d6, or polyhedral dice (d4, d8, d10, d12, d20, d100) used in tabletop RPGs. Results follow a uniform distribution (equally likely outcomes) for a single die.
Step-by-Step Guide
- 1Rolling 1 die: each face has 1/n probability
- 2Rolling multiple dice: sum follows a bell curve (central limit theorem)
- 3Notation: 2d6 = roll two 6-sided dice and sum them
- 4Average of nd6 = n × 3.5 (average of one d6)
Worked Examples
