No Dice? No Problem! Roll20 Has The Free Quantum Dice Roller

This tool is powered by Roll20's QuantumRoll engine, which generates randomness from the fluctuations of a beam of light. Roll20 publishes the results of these millions of rolls so players can independently verify the true randomness of the system. The tool supports Roll20's full dice syntax, including advantage/disadvantage, keep-highest/lowest mechanics, exploding dice, reroll rules, and custom formulas. It also provides built-in presets for Dungeons & Dragons, Pathfinder, Call of Cthulhu, Daggerheart, and others. Customizable Quick Roll buttons let players save their custom formulas, and the D20 Roll Report provides a shareable summary of your session's rolls.

"For years we've had the best dice engine in the hobby, tested across billions of rolls by millions of players, hidden behind a login screen," said Dean Bigbee, Director of Operations at Roll20. "That felt like hoarding one of our best features. Other online dice rollers don't offer the functionality we're used to within Roll20, and are often reliant on math.random() formulas that can't compete with our QuantumRoll engine. Now, anyone who needs to roll dice, simple or complex, can do it instantly and trust every result."
