Two great statements from The Aaron and Drespar respectively: The QuantumRoll page of the Roll20 Wiki is definitely worth checking out. QuantumRoll is actually more random than physical dice . Further discussion and readings on this topic: <a href="https://app.roll20.net/forum/post/63487/from-the-source-roll20-rng-testing" rel="nofollow">https://app.roll20.net/forum/post/63487/from-the-source-roll20-rng-testing</a> <a href="https://app.roll20.net/forum/post/4517173/skewed-dice/?pageforid=4517352#post-4517352" rel="nofollow">https://app.roll20.net/forum/post/4517173/skewed-dice/?pageforid=4517352#post-4517352</a> <a href="http://cocosci.berkeley.edu/tom/papers/hard.pdf" rel="nofollow">http://cocosci.berkeley.edu/tom/papers/hard.pdf</a> This really has been talked to death. Consider that for the 10-20 posts in the last 5 years where people have suggested that the dice engine is not random, there are hundreds of thousands of games with players that didn't post with that suggestion. Read through those links above. If that doesn't convince you, then switch to physical dice. However, remember that the Gambler's Fallacy, also called the Monte Carlo fallacy, got its second name from a physical world event where the roulette wheel came up black 26 times in a row, a probability around around 1 in 136.8million. You can't escape Gambler's Fallacy. We actively track the randomness of every roll on Roll20, you can check out the stats of rolling a d20 at where Aaron has already linked: <a href="https://app.roll20.net/home/quantum" rel="nofollow">https://app.roll20.net/home/quantum</a> To reiterate, we do keep a close eye on the status of the QuantumRoll system and you can track if perhaps it went down for a brief moment (it hasn't) here: <a href="http://status.roll20.net/" rel="nofollow">http://status.roll20.net/</a> If at any point it does go down, you will not longer see the QuantumRoll symbol showing in your rolls when you hover over them. Unfortunately, this requires the restatement of things already discussed at length in this thread. We have collected years of data that support the graph that you see at the QuantumRoll status page and the claim that it is extremely random. However, if it is believed that the dice roller truly is not random, then we encourage that you perform tests and present your results to us directly at <a href="mailto:Team@Roll20.net" rel="nofollow">Team@Roll20.net</a> so we can better investigate.
