Frequently Asked Questions
Can physical dice be more biased than this digital roller?
Yes! Physical manufactured dice often have air pockets or imperfect tumbling edges that skew results. Digital CSPRNG dice rolls are mathematically uniform and unbiased.
What is a Natural 20?
On a d20 die, rolling a 20 is known as a Natural 20 (or critical hit), representing the highest possible roll before modifiers are added.
Which tabletop RPG dice notations are supported?
The roller supports standard polyhedral RPG dice including d4, d6, d8, d10, d12, d20, and d100 (percentile), with custom quantity multipliers and positive or negative modifier math (e.g. 2d20 + 5).
