Here is the original accusation against Dream.
And here is Dream's reply.
"Matt flips a coin 100 times."
"Holy Craps! How a Gambling Grandma Broke the Record",8599,1901663,00.html
Number of casinos in the world in 2011: 3,547
Roulette records.
- At 09:08 I say “1 in 110 trillion” when I meant to say “1 in 110 billion”. The number on the screen is correct, it was just a verbal slip-up.
- At 25:27 I showed the 118 craps record as “1 in 1.2 × 10^9” when it should be “1 in 2.2 × 10^9”. The voiceover says the correct number.
- I slip and “more likely” instead of “less likely” at 33:47 (I think I may have even been going for “more unlikely”). But everything in the screen is correct.
- Let me know if you spot any more mistakes!

    • I love minecraft, and find it too be highly mathematical, I am sure you found this to be true as well, I came for the math though and thanks. My fahter and I both actually love this game, we use the mathematics embedded in the game to create massive structures in Survival. And in doing so, we learned to count at incredibly fast rates, although, only usually based on 2 and 4 though, or sometimes 64 if we must. It has created an interesting view for myself, as I began to notice real mathematical patterns in the real world, which was really wild.

Genetic mutation probability would then have an upper bound so you could compare that to the known amount of mutation over a hundred years- kinda like another ruler for genetic time. Would need to compensate for the number of human genomes on the planet at the time and all that and i might be hella wrong lmao

  • This is funny because I was accused of hacking a game site to win more on the slots. This is a free play site so no money involved, unless you are one of those people who buys more credits. On the other hand, if they did offer to buy back credits at the same price they sell them for, I could buy a small country, say, Australia. It wasn't hard to do because their random numbers generators sucked and they didn't use the same process used in the slots played in casinos. Combine that with being able to figure out that, if this game was winning and stopped, then the odds were that the one next to it would pay out. I assume the accusers were playing the ones they thought were cute. They have improved their method of not paying out.

    • Prior to getting caught Dream had complained on his Discord that he was having trouble with ender pearl and blaze rod drops specifically, and those two RNG factors are what by far matter the most for speedrunning in that version. So it would still be suspicious if all of the other RNG factors came up as normal.

      Agent DAgent Dپیش 15 ساعت
    • Not really. The probability is so phenomenally small that the chance of this set of runs ever having occurred is so close to zero as to be comical. Imagine taking a six-sided die, trying to get 6's, and rolling a six 25 times in a row. No other context matters, that die is loaded...... Dreams speedrun is about 1% as likely as that. The main thrust of the last 10 minutes of the video is that the chances are so, so low, that no amount of correction, or crazy luck, could possible justify it. In his words (Paraphrased): If every human on the planet did those minecraft speedruns every second for the next century, it still probably didn't happen, ever, to any of them.

    • Mods addressed that in the original paper. Dream's expert massively overcorrected in his response. But the point of this video is that no amount of bias saves this probability.

  • I must say though that Minecraft stadistics seems to be wrong. I have done the maths for what is the aproximate amount of gold you would get by mining with Fortune (I, II and III) and without on the nether. I then did many tests in game and saw a youtuber doing so. By statistics the amount you should get was waaay lower than what you would always get. Therefore whenever you have certain probability for something in Minecraft i would not take it as a garantee stat. I have no opinion in the Dream stuff it self, though i tend to trust the numbers. But i think Minecraft supposed stats might hide something, probably other codes change those probabilities to be higher than they seem.

  • Do the stats change for a game of skill compared to a game of chance? I’m sure if Shane Warne was going to improve with skill when trying to spin a ball onto leg stump that would be different to him rolling dice to see if he could do it. Also like your own ball skills.

    joeleusjoeleusپیش روز
    • @joeleus That's a much harder question. It's easy to find examples of clear cut skill games, and clear cut skill games, but the line in between is really, really fuzzy. Take Overwatch, a game that is largely skill. Despite the level of skill, a number of things can change the outcome. This includes things like certain skins (Farah's Frostbite is an example) giving you unquantifiable advantages (Being hard to see against the daytime skyboxes) as well as the fact that the system used to determine matchmaking, which would likely try to make sure that all players win from time to time, but may also randomly match you with a smurf account (A high level player pretending to be a low level player). Add in the simple questions of starting character selection, and the skill/luck/pay question becomes virtually impossible to answer. So with that being said, my answer is far, FAR, from conclusive, but here is my definition. Are your inputs and decisions making a clear difference in the outcome of the situation or game? If the answer is yes, than there is skill involved in that part of the game. If the answer is no, and there are still multiple possible outcomes, than it is luck. The problem is, almost all games balance luck and skill, and even corporate greed, to some extent. Worse yet, luck and skill are often blended, many games have variable damage, where your damage numbers have a random element, but hitting the mark is still skill. Even chess, hailed as a pure skill game, has a piece of luck at the beginning of the game. Who goes first?

      Shadowrider1134Shadowrider1134پیش 18 ساعت
    • @Shadowrider1134 and that opens up another train of thought. How do you judge whether a game requires a significant amount of skill that a proportion of training or effort will change the distribution of outcomes? The gaming industry is gigantic and I’m sure many people believe they are developing skills when they play. I’m sure most of the gaming businesses regularly tweak their programs to make sure skill doesn’t ruin the illusion of their business models which rely on micropayments and grinding.

      joeleusjoeleusپیش 18 ساعت
    • Yes. Stats become largely irrelevant in games of pure skill. Usually there is some small element of luck, but it can be reduced to basically 0. Imagine a professional chess player playing chess against an average 7 year old, no one would be very surprised to see 100, even 200 wins in a row. But flipping a coin and getting heads 100-200 times in a row is unthinkable.

  • I know nothing about Minecraft and little about Speedrunning, so i'm a bit confused at Mats comments ~10:30 - if this run would have been "only" the 4th fastest, why is it even so controversial. And if one needs such incredible unlikely luck to get such times .. what about all the others [above/around him], wouldn't they be at least as unlikely? Did i miss something?

    Michi R.Michi R.پیش 2 روز
    • @Michi R. Another thing that is worth remembering is that other players managed to complete the parts of the game that don't rely on luck (travelling, mining, building, etc.) faster than dream because they are potentially better at the game than Dream. Going faster in and of itself cuts down a lot on time.

      Daniel RhodesDaniel Rhodesپیش روز
    • Ah yes, i guess i forgot about that and thought that's chances over one run. That makes more sense - thanks guys!

    • Dream is accused of altering the drop rates over 6 streams totalling about 24hours of gameplay. Other runners have had better individual runs but Dreams lucky streak over 24 hours is impossibly lucky due to the law of big numbers.

      morbideddiemorbideddieپیش روز
    • Luck is part of it, but it's not the entire thing. Secondly, the one in twenty sextillion is for the drops across the six livestreams, not for his final run.

      AthenriAthenriپیش روز
    • It wasn't mentioned in this video but up until the very last part of the run, Dream was on pace to get the world record, and it only ended up not being the case because he had to go back and get more eyes of ender thus wasting a lot of time

  • I'd be interested to know how the Minecraft code creates the 'random' element of these drops. Developers generally use algorithms to create 'puedo-random' numbers, true randomness isn't really achievable in most cases. Depending on the 'randomness algorithm' at play, the distribution of values may be more predictable than suggested here. Nevertheless, an excellent breakdown of the mathematics at play.

    Matt SokolowskiMatt Sokolowskiپیش 2 روز
    • The random number generators are attached to several factors in the world so the amount of white noise generated makes them impossible to manipulate. Even if dream was adoring that though he would have to reveal his tactics for the run to be valid anyway.

  • The thing to consider with the casino examples too is there is a human element of those events. Its undoubted that the way the dice were rolled and the dice themselves would dictate heavily on the rolls. The actual odds of the 154 craps rolls is likely lower than what pure math which makes dreams record even more absurd.

  • I'm just here to say that statistics are a lie. Dunno who Dream is or who Matt is, but being a guy who finished a special-math class/direction/specialization thingy in high school (I don't know what would be a correct term/comparison to US since I'm based in EU, but it's made of 4 years of study from mostly different math and I.T. classes) and also being a person with 130+ IQ I gotta say that statistics are a big lie and deception. :) And the term "on average" is the biggest weapon of deception (of them all) that can throw numbers in your favor or against you [or anyone else] whatever you like/prefer. Be simple, be binary is my motto; everything in life is 50-50. How? -Well it can either happen or not. You will either win or lose, rod/pearls will either drop or not, you'll either guess where is the ball (under which cup) or not, live or die and so on... Nothing in life (or in our case in games) is perfect and there is always a chance to improve your result, so pushing ourselves to constantly do more/bigger/better is an inevitable progression. How many planets are there? And how big universe actually is? What are the odds that we (human species) are alone in the whole universe? And what are the odds that "aliens" doesn't possess technology to reach our little black corner of space? Yet there aren't concrete proofs that we ever encountered other species so far. Or did we [if they don't look nothing alike we are so stubbornly representing them]? :) You see, it's all part of the viewing point. Once a great man said: "You shouldn't doubt everything, you should question everything, only then you will find a true wisdom", I would rather say it is called 'the process of evolution'. :) #JustDoItNothingIsImpossible

  • So dream got 42 pearls out of 262 barters. I’m not arguing for or against dreams innocence, but something all non minecrafters should know is that every speed runner stops bartering after they reach a target number of pearls. With that being said the last barter in any speed run would/should always end in a pearl. So the last barter in each analyzed run should not be analyzed as it is “fixed” as being a pearl. Since 6 of dreams speed runs were critiqued wouldn’t we need to subtract 6 from both the successful attempts and the total attempts when calculating the bartering probability? 36 pearls out of 256 trades not 42 out of 262.

    Austin DowningAustin Downingپیش 2 روز
    • Not how it works. Only the last trade of the last run is guaranteed to be a success. Why not the runs in the middle? Because think about what happens after you end a run; you start another one. Another comment put it best. If you're flipping a coin over and over, and every two heads, you stand up and shout "I can kill the Ender Dragon!", does that mean you can cut out every second heads result to get the rate of your coin? (Also it was 6 live streams, not 6 runs. It was 33)

    • And to add on to what the previous person said there’s multiple aspects to a speed run in Minecraft such as Biome spawns Village spawns Nether spawns How far the nether portal is How many eyes are already in the portal How close or how far the nether fortress is How many eyes break on the way there Temple spawns How fast you can craft How fast you can kill the dragon And many many more. So no, also dream’s run would’ve been at the very least top 3 if one more eye would’ve been in the portal or if one of his eyes didn’t break. Minecraft is reliant on RNG and that’s why there won’t ever be a “perfect” run and also since Minecraft is constantly changing.

  • Honest question, cause I really don't know the answer. Isn't it possible, even if the odds are astronomically low, that someone attempting to perform a certain action could perform that action on the first go? How can you say with certainty that a human could never accomplish it when in theory it could occurs on the first attempt? Disclaimer: I honestly have no idea who Dream is and have zero investment in whatever drama they've caused. Just genuinely curious.

  • One interesting thing in relation to dream speed run that I feel like nobody has ever paid attention to is the fact that Minecraft runs on Java and Java's random number generator is not perfect using the time as the seed as in most cases every millisecond will create a different seat for a random number so if two actions call the random number generator within milliseconds of each other the chance that the random number is the same is great is highly likely this can easily be demonstrated by making a program that calls it get random number feature and runs it once every millisecond to every 10 or so numbers you will get a string of 10 numbers that are the same number using that random number generator based on the time so therefore if piglin trades were happening at the same time the chances that they would create two ender pearl traits based on the same random number using two different people would mean that the chances if you had two pigs to get two trades of pearls is actually the same as one piglet giving one ender pearl

    • @Isaac Newton You're now talking about the periodicity. When a PRNG runs out of numbers in its sequence, it starts to recycle, beginning from the first output once again. This does have an impact on its overall randomness, but only once you start to recycle the values. So what's the period of Java Random in particular? It uses a 48-bit seed. In other words, the period is going to be just a tiny bit less than 2^48, or 281 trillion. That is, after 281 trillion random numbers being output will you run into the issue of random numbers repeating in the same order as the first time around. Going by the mod team's range of 6000-9000 random numbers called from world RNG per game tick, and there being 20 game ticks in a second, even if you highball and say every game tick makes 9000 random number requests, you would need to play for: 2.81E14 / (9000 x 20 ticks/seconds x 60 seconds/minute x 60 minutes/hour) = 434 374 hours. In other words, irrelevant for our 24 hours worth of sample data. Made even less relevant that each time Dream starts a new run, the seed of the world RNG changes. The only time that the periodicity of the PRNG comes into play was if someone was to play 434K hours of Minecraft STRAIGHT in one sitting, in one single world. And time is not in the equation. Time is just a component of the seed. The mathematical PRNG equations do not use time themselves. Again, section 9 of the mod team paper goes over the periodicity in more mathematical detail about why it has effectively no impact here. As an aside: > why Mojang created it so that all penguins reference a single list of random numbers set for the piglins, why not have each piglin have its own instance of prng There's pros and cons to both approaches, and Minecraft actually uses both methods. The Blazes for instance make a new PRNG each time they die to determine their drops. Having a "master" PRNG control everything (or in Minecraft's case, mostly everything) is actually accepted practice in most situations, as it makes it less likely a player can manipulate that seed to their liking. Since it only happens on world load, that means a player can't really interact with it in any meaningful way during the course of a session since it's already been set, and it's being used in too many places to effectively keep track of where you are in the PRNG sequence. The only real disadvantage of this strategy is potential for lag; that is, if too many things need random numbers from this one generator, parts of the game could stall if the PRNG can't spit out numbers fast enough and force them to wait their turn for a value. Even at 9000 near simultaneous requests though, Minecraft is quite well below whatever limit Java Random has. Instantiating a new PRNG really is just there to dodge that problem. Since these get seeded on each mob death, there IS a chance that a player can manipulate the time to try and alter their results favourably. That's why Minecraft is smart and throws a wrench in those plans by seeding not only the time by itself but XOR'd with another random number from another PRNG which can't be manipulated by time because it has a set seed and is also called a random number of times so there's no telling where it is in its sequence either.

    • @JuukaRock thank you for clarifying, I have never had the opportunity to read how the code for penguin trades works myself, the question still does remain when prng gets another number for the list or generates a whole other set how is it doing so, it also begs the question of why Mojang created it so that all penguins reference a single list of random numbers set for the piglins, why not have each piglin have its own instance of prng. Or likewise each piglin could have its own prng which would be seeded with its uuid? The only basis for my comment is the fact and that Java random is not random, nor is any computers random actually random, because computers are based on logic computers can only create logical answers, we can create complicated functions that take in lots of different variables and do some very complicated math to make them seem more random but they are in fact generated from non random things. Errors in implementations in such randomizers can create odd patterns making the random sequence of numbers less random for lack of a better term. This can be better seen in sloppy implementations of random functions, Javas is better than some it is definitely not the best. My point still stands if you generate a list of 10 trade integers, at some point your list of integers will run out and you will have to generate more, when you generate these integers they will be generated very quickly between them. Whether you stock the list by adding one as soon as one gets removed or by generating a completely new list when the first one is empty, my point remains the same about the random numbers being generated based on time and probably other factors, which means that random numbers generated in quick succession have a higher chance to be the same number than ones created different times apart. This of course can be negated by using other variables and combination with time to make the values "more random" but any inclusion in time in the random equation will mean that random numbers close together will be more likely to be the same. Especially when generating numbers within a very small range. The smaller the range the more likely to get the same number in a row more often.

    • @Isaac Newton > principal remains the same No it doesn't, your principle is wrong because your understanding of how RNGs work is wrong. > RNG is called super close together there is the possibility that the same number will come out twice No. This is not how it works. Let's do an example. Say I have a PRNG, and that for the sake of this example, only Piglin trades request from this PRNG and nothing else (this is not how it works in Minecraft, this is purely for this teaching example). This has a pre-determined sequence of values. Since Piglin trades are out of 423, let's say I request 10 numbers from my PRNG for 10 trade results. I make a save state right before. I do this one with 10 Piglins simultaneously. My results are: 302 78 17 221 259 405 161 84 318 385 Even though the 10 trades happen all at once, the PRNG still needs to spit out the numbers in some sort of sequence because they aren't using multiple PRNGs, they're only using one, so it only ever goes one number at a time (it just happens so fast it's like it's simultaneous to us as humans). So my first Piglin rolled a 302, my second Piglin rolled 78, my third rolled 17, etc. etc. etc. I reset and load my save state and do my 10 trades again, but this time, I only use one Piglin and I wait a minute between each trade. Do you know what my PRNG results will be? You guessed it, it's 302 78 17 221 259 405 161 84 318 385 In other words, my single Piglin rolls a 302 for the first trade, then a 78 for his second trade, then a 17 for his third, and so on. The time does not matter, nor does doing them "simultaneously". One single PRNG can only spit out numbers one at a time, so requesting numbers from it all at once does not mean anything will receive the same value necessarily.

    • @JuukaRock more specifically what I'm referring to is yes the random number generation is based on some more complicated factors than just one RNG but the principal remains the same since the RNG is called super close together there is the possibility that the same number will come out twice. What I didn't articulate very well in the first post is, say I create a for loop which calls 100 times to get a random number from the random number generator 5 to 7 of them sometimes 10 depending on random number generation will be the same number even though it is called several different times, if the random number generator were to be called very close together such as dropping a stack of gold to several piglins where the more piglins you have the more likely they will all pick it up at the same time, the more likely you are to get the same trade from two piglins. This is happened to me in the game where I will be trading with three or four or five pigments at the same time and sometimes two and even three of them will give me the exact same trade at the same time even same amount, now yes this is pretty rare and doesn't happen very often but it's still possible taking in consideration that we have a small sample size when talking about these and there have been no direct studies on the subject of how often you could reliably get a double trade it's hard to tell exactly how this would affect the probabilities, but even just happening a few times because of the small sample size would be enough to dramatically shift the probabilities.

    • > I feel like nobody has ever paid attention to The first mod team paper (like, all of section 9), the accompanying video by Geosquare and 35:36 all address this to varying degrees, the most detailed of which is the original white paper. > using the time as the seed as in most cases every millisecond Nanosecond actually, so 1000 times more narrow to hit the exact same time as another instantiation. Also, Minecraft RNG is seeded not only by the system time in nanoseconds, but that is XOR'd with a number from an LCG (another RNG). So even if you do something like freeze the system time, you aren't going to get the same seed between different RNGs. > easily be demonstrated by making a program that calls it get random number feature and runs it once every millisecond to every 10 or so numbers you will get a string of 10 numbers that are the same number Doesn't work like that. You can get identical results if you pass in the same seed to different RNG objects and get the same number of outputs from both of them. However, if you're using only one single RNG and calling numbers out of it, it will be random enough, and the time that you ask for the next random number isn't going to matter since the order is already pre-determined by the seed. With regards to Piglin trades, they use the same RNG, the world RNG that is called thousands of times per game tick due to lava and netherite blocks calling it repeatedly to render how they do their animations. Because of that, no human player can accurately predict where in the PRNG sequence they are. Trading with multiple Piglins all at once doesn't matter since they'll be calling numbers from the PRNG in some sort of sequence, even if it LOOKS simultaneous to us as viewers and players. Java Random's cryptographic weaknesses here aren't relevant, especially with how Minecraft uses it.
