Dice Roller

What Is a Dice Roller?

A dice roller is a digital simulator that replicates the random outcome of throwing physical dice. This tool uses cryptographically secure random number generation to ensure each roll is fair and unpredictable, just like rolling real dice. It supports the standard set of polyhedral dice used in tabletop role-playing games (RPGs), board games, and probability exercises — from the common six-sided die (d6) to the percentile die (d100).

How to Use

Select a die type (d4 through d100) and the number of dice to roll. Click Roll to generate results. Statistics including sum, minimum, maximum, and average are shown below the results.

Supported Dice

Standard tabletop RPG dice are supported: d4 (tetrahedron), d6 (cube), d8 (octahedron), d10 (decahedron), d12 (dodecahedron), d20 (icosahedron), and d100 (percentile). Each roll uses cryptographically secure randomness.

Common Use Cases

• Tabletop RPGs — roll for attacks, damage, saving throws, and ability checks
• Board games — simulate dice when physical dice are unavailable
• Probability learning — explore distributions and expected values
• Classroom activities — teach statistics concepts with hands-on experimentation
• Decision making — use random rolls to resolve ties or make fair selections

Features

• Seven standard polyhedral dice types (d4, d6, d8, d10, d12, d20, d100)
• Roll multiple dice at once (up to 100)
• Automatic sum, min, max, and average calculations
• Cryptographically secure randomness for fair results
• Instant results with no page reload required
