Frequently Asked Questions
Is this the same as rolling a d8 die?
Yes. This produces the same uniform distribution as a fair 8-sided die, with each number having exactly a 12.5% (1/8) chance. Since 8 is a power of 2, our cryptographic generator achieves perfect uniformity with zero modulo bias.
What tabletop games use a d8 (1-8 range)?
The d8 is widely used in Dungeons & Dragons for weapon damage (longsword, rapier), healing spells, and various ability effects. It's also used in Pathfinder, Warhammer, and many other tabletop RPG systems.
Can I type a custom count, like 6 numbers between 1 and 8 at once?
Yes — the "How many?" box accepts any count from 1 to 1,000 (type 6, 25, 500…), and the quick buttons fill common values. Turn on "No duplicates" when every number must be unique.
How many possible results are there in the 1 to 8 range?
Exactly 8 (counting both 1 and 8). Each has an identical 1-in-8 chance (12.50%) of appearing on every draw, independent of previous results.
