What is a dice roller?
A dice roller is a virtual tool that simulates throwing one or more dice with any number of sides. Instead of reaching for physical dice, you can generate fair, random results instantly in your browser. This tool supports the full range of common tabletop dice—d4, d6, d8, d10, d12, d20, and d100—as well as custom-sided dice up to 100 faces. Whether you are playing Dungeons & Dragons, Monopoly, or creating your own game mechanics, this roller has you covered.
How to use this roller
Select the number of sides and the number of dice you want to roll. Use the quick-roll buttons for popular configurations like 1d6, 2d6, or 1d20. Click Roll Dice to start an animated roll that cycles through values before landing on the final result. Each die appears as an individual tile—standard six-sided dice display classic Unicode face characters for a familiar look. When rolling multiple dice, the total, minimum, maximum, and average are calculated automatically so you can see the full picture at a glance.
Fairness and randomness
The final roll uses your browser's crypto.getRandomValues() API—the same cryptographic random number generator used in security and encryption. Every face has a truly equal probability of appearing. The animated spin you see is purely visual and does not influence the outcome, so every roll is fair and unbiased.
Popular use cases
Tabletop RPG players use virtual dice for attack rolls, saving throws, and damage calculations. Board-game enthusiasts roll online when physical dice are unavailable. Teachers use dice rollers for probability lessons and classroom games. Party hosts use them for trivia nights or icebreaker activities. Developers and designers use random dice for generating test data or deciding between options. Because the tool runs entirely in your browser with no server calls, results are instant and private. A roll history keeps track of your recent outcomes so you can review past rounds without writing anything down.
