About this tool
The Dice Roller is a virtual dice tool that lets you roll any number of dice with any number of sides, from the classic six-sided d6 to the d20s used in tabletop RPGs and beyond. It is built for gamers, teachers, game designers, and anyone who needs a fair random result without rummaging through a bag for physical dice. No signup, no download, just instant rolls in your browser. The results are generated using a cryptographically random number source so every roll is genuinely fair and unpredictable. Whether you are running a dungeon campaign, teaching probability in a classroom, or settling a friendly dispute, this tool handles it cleanly.

FAQ
Are the rolls truly random?
Yes, the tool uses a cryptographically secure random number generator rather than a basic math function. Each result is statistically independent of the last.
Can I roll dice with unusual side counts like a d7?
Yes, you can enter custom side counts beyond the standard presets. Any positive integer works as a valid die face count.
