What Is a D10, and How Do I Roll One Online?
The D10 is a ten-sided die shaped like a pentagonal trapezohedron, numbered 0–9 or 1–10 depending on the set. It's the core mechanic die in dice-pool systems like the World of Darkness games (Vampire: The Masquerade, Werewolf: The Apocalypse), where players roll a handful of D10s and count successes, and in Dungeons & Dragons it's used for weapons like the heavy crossbow and as a hit die for fighters. Paired with a second D10 read as the "tens" digit, it's also how a physical percentile roll is usually made. RollAD20 rolls a single D10 instantly, or a whole pool at once if your system calls for several.
Frequently Asked Questions
What is the average roll on a D10?
5.5 — the midpoint between 1 and 10, calculated as (1 + 10) ÷ 2.
What games use dice pools of D10s?
World of Darkness games like Vampire: The Masquerade and Werewolf: The Apocalypse are the best-known examples — players roll a handful of D10s at once and count how many land above a target number, rather than adding up a total.
How is a D10 different from rolling percentile (D100)?
A single D10 gives a result from 1 to 10. Percentile rolls combine two D10s — one read as the "tens" digit, one as the "ones" — to get a number from 1 to 100. If you need percentile results directly, RollAD20's D100 roller gives you that number in one roll.
Is this dice roller random and fair?
Every roll uses your browser's cryptographically secure random number generator (the Web Crypto API), so every face has an equal chance of coming up — the same fairness you'd expect from a physical die, no biased algorithm involved.
