Random D8 Generator

Roll an 8-sided die (D8) with a real tumbling 3D animation, for tabletop RPGs, board games, or anywhere you need a random number from 1 to 8.

About this generator

This rolls a genuine 8-sided die (an octahedron), with a real spinning 3D animation rather than just a number changing. Results are always 1 through 8.

Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.

What people use it for

Tabletop RPG players use it for d8-based damage rolls and other mechanics without digging out a physical die. It's also useful for any quick decision with eight options.

How it works

Rolling draws a value from 1 to 8 using the site's cryptographically secure randomness, guaranteed not to repeat whatever result is currently showing. The 3D octahedron animates through a real spin before landing on the result, matching the number shown.

Common questions

Is this a true 8-sided die roll?

Yes -- each roll is a genuinely random value from 1 to 8, not a fixed or fake sequence.

Can I roll more than one D8 at once?

Yes -- use the amount selector to roll up to 100 D8s in a single click.

Will it show me the same number twice in a row?

Not in single-roll mode -- each new roll is guaranteed to differ from the one currently on screen.

Is the animation just for show, or does it reflect the actual result?

It reflects the real result -- the die visually settles on the same face as the number shown.
