What is an Online Dice Roller?

An Online Dice Roller is a free virtual tool that simulates rolling one or more dice with a click. It supports standard 6-sided dice as well as polyhedral dice (d4, d6, d8, d10, d12, d20, d100) used in tabletop RPGs like Dungeons & Dragons. Each roll uses cryptographically secure random numbers for truly fair results. Perfect for board games, RPGs, probability experiments, and decision-making.

Why use a virtual dice roller?

Virtual dice are always available, never get lost under furniture, and provide provably fair results. For tabletop RPGs, rolling multiple dice simultaneously with instant sum calculation saves time. For probability education, you can roll thousands of dice to demonstrate statistical distributions. It also keeps a roll history for reference and resolves any disputes about physical dice fairness.

Supported dice types

d4 (tetrahedron): pyramid-shaped die, often used for small weapon damage in D&D. d6 (cube): standard die, used in most board games. d8 (octahedron): used for medium weapon damage. d10 (pentagonal trapezohedron): percentage dice. d12 (dodecahedron): used for heavy weapon damage. d20 (icosahedron): the iconic D&D die for skill checks and attacks. d100: percentile rolls using two d10s.
