Frequently asked questions
- Is a d20 roller the same as a physical twenty-sided die?
- Statistically, yes — each roll is drawn uniformly from 1 to 20 using a cryptographically secure random number generator, so no number is more likely to come up than any other.
- Can I roll with advantage or disadvantage?
- This tool rolls a single d20 at a time. For advantage or disadvantage — rolling twice and keeping the higher or lower result — use the dedicated Advantage/Disadvantage Roller instead.
