About This Online Dice Roller
Whether you are running an evening tabletop roleplaying game, playing classic board games like Monopoly or Yahtzee, settling classroom turn orders, or teaching probability math, this free digital dice roller gives you authentic 3D dice rolling on any device. Every throw calculates individual results, total sums, arithmetic averages, and minimum/maximum ranges with local cryptographic randomness.
All Standard Polyhedral Dice
Full 3D geometric modeling for d2 coins, d3, d4 tetrahedrons, d6 cubes, d8 octahedrons, d10 trapezohedrons, d12 dodecahedrons, d20 icosahedrons, and dual d100 percentile dice.
Unbiased Cryptographic Math

Frequently Asked Questions
How does the online 3D dice roller generate random results?
Our online dice roller uses the browser Web Cryptography API (crypto.getRandomValues) to select unbiased random numbers locally on your device. The 3D animation visualizes the selected outcome with physics-based tumbling.
What types of dice can I roll?
You can roll standard polyhedral dice including d2 (coins), d3, d4, d6, d8, d10, d12, d20, and percentile d100 dice, as well as arbitrary multi-die quantities up to 30 dice at once.
Can I drop lowest dice or add modifiers?
Yes. Expand Advanced Rules to set Drop Lowest, Keep Highest, static bonuses or penalties (+/- modifier), rerolling 1s, or enter standard RPG formulas like 4d6dl1 directly.
Do I need an account or software download?
No. The 3D dice roller is completely free, runs 100% in your browser, requires no account or registration, and works on desktop, tablet, and mobile devices.
