Roll20’s Quantum Dice are literally the best digital dice in town. It’s a bold claim, but we stand by it! They utilize a “true random” source of entropy, based on the fluctuations in the power of a beam of light.
But those dice were always trapped inside the Virtual Tabletop. No longer. We’ve let Schrödinger’s Dice out of the box, and you can now have quantums in your pocket everywhere you go!
Head on over to d20roller.com to find our dice roller on desktop and mobile. It utilizes the same Roll20 QuantumRoll engine you trust, has all the advanced roll mechanics you rely on, includes customizable one-tap buttons, and offers a mega-dose of Big Dicey Energy!
Deep Dive on our Dice Engine and Roller
Verifiable Randomness
The most common complaint about digital dice is that they “feel rigged.” We address this directly with receipts. Every roll goes through our QuantumRoll dice engine, and generates verifiable seeds. We publish millions of results so you can check the math yourself.
Advanced Dice Syntax Support
We provide built-in presets for D&D, Pathfinder, and other systems, but you can also write your own custom formulas, as complex as you want. Some examples of how deep our syntax goes:
- 2d20kh1
Advantage! Roll 2 d20’s, and Keep Highest (kh) 1 roll.
Want to turn into into disadvantage? Swap kh1 for kl1 to Keep Lowest 1! - (1d8+4)*2
Critical damage multiplier. This rolls 1 d8, adds 4 to the result, then multiples that total by 2. - 3d6>2
Tally successes. Rolls 3 d6’s. It then provides you a count of every dice that resulted in 2 or greater (a tally of successes, not a sum of dice results) - 8d20ro1
Reroll! Roll 8 d20’s. Any 1 gets Rerolled Once (ro), and that new result sticks even if it’s another 1. You can swap ro1 for r1 if you want it to keep rerolling until it’s not a 1! - 10d10!
Exploding dice! Roll 10 d10s. Every time the result is 10, the dice will explode and roll an extra dice. - {10d10!>7}>8
Exploding Dice, with extra features! Roll 10 d10’s. Any dice that’s 7 or greater will “explode”, meaning a bonus d10 will be rolled. Then it counts up every resulting die that’s 8 or higher and gives you that count as your total.

Only the tool you need
We’ve been running virtual tabletop game nights for over a decade. We figured if we already built the best dice engine, we should free it from the VTT. When you’re ready for maps, tokens, character sheets, and friends across four timezones, that’s what hopping into Roll20 is for.
