Roll a 20-sided die (D20) with a real tumbling 3D animation, for tabletop RPGs, board games, or anywhere you need a random number from 1 to 20.
This rolls a genuine 20-sided die (an icosahedron) -- the signature die of modern tabletop RPGs -- with a real tumbling 3D animation rather than just a number changing. Results are always 1 through 20.
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.
D&D and other d20-system players use it for attack rolls, saving throws, skill checks, and every other core mechanic those games run on, without needing a physical die at the table. It's also useful for any quick decision with twenty options.
Rolling draws a value from 1 to 20 using the site's cryptographically secure randomness, guaranteed not to repeat whatever result is currently showing. The 3D icosahedron animates through a real tumble before landing on the result, matching the number shown.
Yes -- each roll is a genuinely random value from 1 to 20, not a fixed or fake sequence.
Yes -- use the amount selector to roll up to 100 D20s in a single click, useful for rolling with advantage/disadvantage or a whole group at once.
