Try Diplomacy (the game) you will probably love it and they will either kill you for real or expel you or leave the house. No luck it's rules simpler than monopoly. Making deals then backstabbing is how you win frequently as coming up with superior orders every turn with the limited options really hard. Unlike most game several versions of cheating are allowed. One I love the most is if you can sneak a new army or navy piece on the board and no one catches you it stays.

@Ava I know that Elizabeth Maggie invented monopoly. In any case that's a pretty odd argument against land value taxation considering you can just do both (which is even more relevant of an idea now, when tech companies can make huge money with hardly any footprint, and that's ignoring day traders)
Ava Gün önce
@Colby Boucher Elizabeth Maggie was the inventor of Monopoly. And she was somewhat outspoken against land value taxation as it didn't account for the value that human labor ads. Henry George was pretty much just an inspiration of hers. That would be like crediting Steve jobs with the creation of Apple silicon when he died before that idea was ever thrown around
Colby Boucher
Colby Boucher Gün önce
@Ava *Sort of. It was a critique of land ownership, Henry George wasn't against capital itself per-se. He believed that by distributing wealth generated by the land itself equally (his idea was to do this by making a tax on the value of the land itself the only real tax), the relationship between labor and capital would become something more equitable. There's a theory that his ideas about the value of land were more or less buried by rich landowners paying economists to come up with more favorable explanations for things. Like, not in an intentional, conspiratorial way, but still. He was a fairly popular figure until his ideas mysteriously just faded away.

I have only one gripe with the AI: Not only should it be winning when playing against the other AIs, it should also need to win against some control-AIs making sure that their strategy also works against other AIs that don't feat the way the NEAT AI has evolved. The way you did it the AI could still be pretty bad against a lot of players because the sample range of playing styles wasn't big enough

@Jorge Rolando Chávez Mackay Actually, their strategies are not weird. Their strategies are superhuman. They are built on the exact same foundation we already know. However, chess is an insanely complex game. And humans are incapable of thinking in such complexity. Alpha zero has hundreds of years of experience, larger computational + memory abilities and is devoid of emotion. So it finds strategies that are completely understandable from human perspective... but a human would not find them due to lower capabilities.

My favorite strategy is to buy as many houses as possible, but not turn any into hotels. There are only 32 houses available in a traditional Monopoly set, and opponents won’t be able to build properties if you hold most/all of them. For this strategy, owning the browns and light blues is important because their houses are cheaper and thus you can hog more.
Robert Law

@twizzm It is well documented to use this strategy, and why the number of houses left in the bin is a critical factor to decide whether to build some or not.

@Awesomekk Me and my boys play monopoly plus on xbox like every week and this strat comes up literally every other game. The easiest set to win with is light blues, because psychologically nobody ever feels threatened by them, but they have the highest return for their cost regarding houses, so it ends up being that we trade properties so that each player gets a completed set and the player with the cheaper houses tends to win because they can more easily and safely build hotels, or easily drop down to 4 houses in order to block a new set from building them.

@Sawyer Beaton I've had more wins with orange. There are 16 chance cards. Which means you have a 1 in 16 chance of going there, or 6.25%, and that's it. Rolling from jail, even just visiting, puts you at a high chance of landing on orange or red, which is why I got for those 2 properties. And that's also not true, there are plenty of other "Advance to" cards as well.
Sawyer Beaton
Sawyer Beaton Gün önce
Reds > Oranges because of the Advance to Illinois Ave Chance card makes it the highest landed on single property in the game + higher payouts than the oranges. Yellows are 3rd best and I've won many games with them. The rest of the sets don't matter. I buy them up only to trade for one of the big 3 and I always win if I can get one. Mortgage everything you have to get hotels on it and then try your best to sit in jail as long as possible. Then just wait and win.
Dark_Rit 8 gün önce
Yeah 2nd railroad worse than the 1st one because of advance to go and other cards and doubles from jail cannot land on the 2nd railroad. Though the odds of a 5 being rolled are decently high if you pay to get out of jail with 7 being most likely followed by 6 and 8. Orange having a cheap housing cost and right next to jail has always been the strength of the orange tiles. With pairs of 3 and 4 landing on orange tiles from jail too, making up 33.33% of the pairs you can roll. Last row is either decent to great with blue + enough capital to get some investment in and reap the rewards or just garbage since the green color set would have to be a pair of tiles like the blue's to ever be worth investing into considering the huge housing cost.

​@b2studios I wonder if in the future humanely-general A.I would keep the same efficiency for the amount of games it can play though, I would assume it would be able to learn with less games like human would be able to learn to play monopoly decently after a single game. also, let's say you give it a task of calculating something. obviously computers do this way faster than humans, however if it just "uses it's computer" would that be the equivalent of a human pulling out a calculator?
IceMaverick 13 gün önce
​@JWCfive If you gave both sides 100 _minutes_ to learn a task, there's a good chance the AI might end up doing it better because it can use that time far more efficiently than a human could, simulating the task thousands of times in the time it takes a human to physically perform the task just once. However, if you gave both sides 100 _attempts_ to learn a task, there's a much better chance that the human will do it better, because both sides only get to simulate 100 practice sessions and a human will learn more explosively and make far more mental connections in 100 attempts than an AI would. The AIs improvement would be precise, but marginal after 1 attempt, but the human would eliminate a very wide range of possible attempts without testing them purely through prediction. Your claim was that an AI would defeat a human with "the same amount of experience", but 'amount' would imply 'number of attempts' as the metric and that statement only holds true for arbitrarily large numbers. AIs would defeat humans with the same _length_ of experience - excluding arbitrarily small numbers of time - because that brackets it under the constant of time, which is equal for both of them; the AI is simply more efficient in how it can use that time.
JWCfive 18 gün önce
@Totally Nothatguy this is untrue. If a human had the same amount of experience as an AI did, the difference is between the extremely precise movements of an AI vs the almost certain variations in play of a human player Edit: actually I think I see what you are saying. But if a trained AI was put up against the best player, it would almost certainly win
Totally Nothatguy

@carlina taylor that’s because an AI can tirelessly run tons of games in a short time. If a person played a Mario course 100 times, and so did an AI, the human would win because 100 *attempts* isn’t enough to be better than humans.

"You know what better than altruism? Winning." Pretty good summary of monopoly. I'm also glad that my gut instincts to buy oranges and railroads is verified by machine learning...although they can't really account for the underhanded deals that normally take place in a Monopoly game. It might not be how the game is meant to be played, but the chaos created by random deals between players is what really makes Monopoly a fun game to play. That and free parking.

The longest Monopoly game I've ever played with humans was somewhere around 3 hours long. We were stuck in a protracted trade negotiation and took breaks to roll the dice. Yes, you read that right, we'd reached a point where there was more negotiating than there was (virtual since it was on my smartphone) die rolling and token moving. The game ended about 10 minutes after one of us finally gave in and made the trade the other wanted. The one who gave in and the player not involved in the negotiations at all lost.

@Hannibal why did you return to this 3 weeks later? it's already out of my head. but imo, I wasn't right but I don't think you're right either, I'd like to think that the majority of fundamental opening theory came from humans, and man sidelines probally came from humans too, I do think that computer occasionally adds new moves to theory, but the more moves, the harder it is to calculate so it doesn't have as much impact as the already established theory that humans developed. If there're any examples of openings that was made from scratch by the computer, please tell me

@Phil Surtees 99.999% of these possible positions are either bad, really bad or plain stupid, as they lead either to a quick loss or a stalemate. The better ones, and more difficult to find are ones that still lead to a loss after a long and otherwise perfect game. It is quite fair to say that most of the **good** ones have been actually found; some might have not been found yet but it is still fair to say that out of these 70 trillion, it is going to be hard to find one that is actually good, and haven't been found yet.

I suppose opening strategy is about providing the most potential for board coverage and access by strategic pieces and optimal opening strategies can be discovered in that way more readily (at least in computational terms) as compared to a neural network. Having not looked into it before, I am curious now if the best opening strategies bear this min/max (achieving optimal “board coverage” in the least moves) principle out versus some other strategy.

One strategy that I've seen used by Dan from Game Grumps is as follows: Once you have a complete set, mortgage all properties that are in a set, shared by another player, and use that money to buy houses and hotels. Another strategy I learned from the Hard AI in Game Grumps Monopoly videos is what I call "The Housing Market Strategy". This is when a player keeps placing houses, but no hotels. The end goal is to use up all the house pieces, making it impossible for other players to buy houses.
Andy Polasek

That's why human meta dictates that you should buy three houses on properties (best return for cost) and never hotels. The fourth house is for draining the supply if you get to it.
NixPanicus 2 gün önce
In the first half of the video, you mentioned that the later a property comes on the board the less chance there is to land on them because of the teleports. You also mentioned the winning AI tended to have the blue properties. I think that probably explains why the brown properties were often in the hands of the winning AI, not because they contributed value to the win, but because if you get to a blue property you're very likely to also land on a brown property on the next roll.

It could be that it needed to expel its accumulation, so that it could continue what it was programmed to do, play the game?

We should all have the same or similar chances. I wouldn't even have needed to gift my brother anything to prevent the robbery / tantrum. If I'd only let something go to auction and allow him to get it for the minimum price he'd have had a way out. All I needed to do is not bid. Or even lose some more money than I strictly needed by paying fair value for it. We could have continued playing and both have fun.

The reason the browns are so great is because theyre easy to land on, buy, then build houses on early in the game. While everyone else is still getting as many properties as they can, you routinely get hundreds of dollars every time they land on one of your spots right after they get their 200.

My personal strategy is to first off but every property possible, even if you don't have the money, mortgage your other properties to get the money. Afterwards selectively unmortgage properties that other players could land on while mortgaging the ones they are not near to cover the cost. It's very risky and not sustainable in the early game, but pays off huge in the late game. There's also the other strategy of just cheating, but that's not as fun.

One issue with mutating the entire strategy distribution is that certain strategies thrive in particular strategy distributions, and since you're measuring fitness against the strategy distribution, you can easily end up in a local optimum. In more human terms, it's possible you end up stuck within some particular meta that is good against itself.

@Nolan Armstrong AI is more efficient and humans have the capacity to make mistakes through their free will. Free will gives an advantage in creativity, in developing something entirely new whether it is art or philosophy. Although neural networks can simulate a new work of art, they cannot create a new form or style in the way humans like to do.
Nolan Armstrong

@Godowsky Godowsky but the problem is playing with humans the game is highly randomized. In the beginning of the game ppl tend to buy almost every property they land on because they have the cash on hand and the goal is to "monopolize" the board, obviously. That's why you have to think ahead multiple moves but it's also extremely risky to not acquire properties at the start of the match. Although I have found out playing conservatively and not super aggro is usually more efficient especially when playing against a wildly enthusiasticly buyer
Nolan Armstrong

@Zorro9129 I'd argue that free will in this circumstance would make the human less efficient than the ai. Humans also sometimes react on emotions and many variables enter playing even a simple game. For example if two humans are betting on a game I'd argue they're likely to play more conservatively. These variables don't exist with ai. Would love to hear your thoughts on this. Cheers

0:42 - No, you mean to say there's an _initial overall_ chance of rolling a double that's higher over the longest stay, affording a potentially better exit strategy. It diminishes each time you don't roll a double; each individual roll having exactly the same odds of getting a double _on that roll_ (1 in 6).

Yeah, not the most exciting ending ever. But it’s basically a science experiment, right? With hypothesis “this AI can significantly improve on typical human player strategy,” and negative results. As a young nerd-ling, I was taught that negative results are important and useful, but often under-appreciated. That description hit awfully close to home, so I resolved to give them the respect they deserve! Must’ve been more than [mumble] years ago, but ya know, I still have a soft spot for them 😂

Well I didn't really learn anything about monopoly I didn't know....I am really good at monopoly and win over 90 percent of the time and my wife has never beat me In 20 games over the years....she obviously doesn't enjoying playing as much anymore.....here are the real secrets to the game and I think most ppl do not play the auction style because that changes the game drastically along with certain house rules about free parking and how much goes in there......ppl that like to put 500 plus all the fines fees in free parking really make the game more luck based as it can be used to keep ppl in the game when thier on the verge of bankruptcy....number 1 rule when u start the game buy everything!!! At least first few turns intill your money starts to get low ...and how do you know your money is getting low?...you only need enough cash on hand to pay for the most costly rental places or cc or chance cards requirements that are currently on the board , so if no one has a monopoly yet you only need about 200 In cash to save and all that other money should be put I. Towards property........so moving on so your almost are broke but u got about 200 dollars and a few properties....u want to get a monopoly as fast as u can!!!! Whatever it takes !!!! And u wanna build fast!!!! You need to mortgage every other property and liquidate all your assets and build at least 3 houses on your monopoly....u want hotels but at least 3 houses or it isn't worth doing it. Obviously boardwalk park place are the beds property but honestly anything past the jail on the board is good enough with a hotel to bankrupt others, also the 2nd set of properties after each right turn are the better property the light blue the orange the yellow and and dark blue, houses cost the same so if you have a choice always go for the 2nd property. Also the brown properties are great to snag if you can because what they do is when your opponent goes past goes and lands there with a hotel all the money they collect will go to you and a Lil more. Now this is important because for some ppl that 200 is the only cash they have rolling in that gives them purchasing power , so taking that away with a hotel on the browns is a great strategy.

@Matt Brown Chess is a great use case for ML and Monopoly isn't. ML works so well for chess because the number of operations for brute analysis of a move is very big, and ML can find latent patterns to shortcut that. For Monopoly, the amount of analysis for what to do in a given turn isn't that much (or more specifically, the marginal increase of the objective diminishes quickly with the more computation you do) Which means that humans can and do perform the analysis themselves in a very short time and there isn't anything new ML can really bring to the table. I wouldn't say ML is infinitely better than brute force; there are best use cases for all types of problem solving.

I always get the browns, my friends knew I called them the crackhouses and highly prioritized them. Nothing better than getting lucky and getting both early, being able to pump some money into them and then pretty consistently robbing 1-2 players from their pass go every go around.

Really cool, but all share the same experiences and react logically to them. This allows for a certain level prediction. So how would it (the final iteration) change its behaviors in reaction to earlier versions of itself? Also would their techniques evolve quicker as a result of playing against a superior opponent? Great experiments frequently leave us with more questions than answers… I NEED ANSWERS LOL

I remember playing Monopoly on the NES, when started it up- it could have up to 4 players. either 4 "PLAYERS" or 1 "PLAYER" with 3 AI or any combo. etc. one day I just put ALL AI! and just set the controller down and watched it as I ate my launch lol it was...................... interesting.......................

It still has to be said that browns are a brutal underdog. First brown with hotel is an instant "anti go" f*** you to the poor person landing on it, and second brown is an easy 2+ houses everytime someone lands on it. Trains and Utilities are also must haves. I've won more games prioritising browns and trains then I ever have rushing down the dark blues

0:45 No. No matter how many times you have previously rolled the dice, the odds of rolling a double will stay the same. The dice don't have a memory of what they have done.

0:41 This is completely wrong, the chances of rolling a double don't increase the more you roll. The chance of rolling a double is always 1/6. The stats you're showing are the chances of you rolling consecutive non-doubles. For example, if you had to estimate the chance of you rolling at least one double with three trials, it would be 42.1%. This does NOT mean that if you do not roll a double on the first two trials that the probability of rolling a double on the third trial is 42.1%. It's still 16.7%. The results of previous trials do not impact the outcome of subsequent trials. This would be like saying if you flip a coin and it lands on tails, the chance of you flipping it again and getting a head is 75%, which is obviously wrong. If what you meant to say was that people who choose to pay to leave jail at earlier opportunities will land on evenly numbered properties less often than people who stay until they either roll a double or are forced to leave, then that is correct. However the way you phrased it indicates a (false) linear time relationship, suggesting that a double becomes more likely with every passing turn.

I was looking for this comment too to see if anyone was as stupid as you in intentionally misinterpreting the obvious meaning. Do you really think that the video was saying what you accuse it of saying? Do you believe it's more likely that you alone figured this out, than the possibility that your interpretation is wrong?

@ZeroKitsune ​ @ZeroKitsune I was also expecting someone to have objected to this false statement. I stopped watching the video after seeing this. Programmers not knowing math? It's like a programmer who can't type - ridiculous. I suppose this will change when AI and speech recognition get better, and, as it is, most of the programming being done for business hardly requires more than a rudimentary grasp of even simple arithmetic.
ZeroKitsune 9 gün önce
I was looking for this comment. Thank you. It may be more likely to land on even spaces if you wait to roll doubles (because you only get out if you roll doubles) but it's completely wrong to imply that the chances of rolling doubles somehow increases by waiting in jail.

It probably doesn't make much difference, but the AI should also track the number of consecutive doubles all players have as their chances of going to jail could affect short term decisions.

I played a Monopoly game with 5 of my friends recently and it was intense lol. Besides the fact that all of my friends are competitive, we only decided to play until one of us went bankrupt. Then afterwards we calculated our net worth and the person with the highest net worth won. Anyways, I wasn't the first to go bankrupt which made me happy. But what's interesting for me is that I got very lucky and acquired Boardwalk and Park Place on my own, and then I ended up obtaining a fully monopoly on green. These two spots are low on the landing probability thing you showed. But in our game, my friends were landing on my spots constantly lol

One of my favourite Monopoly strategies is to buy one property of each colour as quickly and holding on to them. This prevents other players from building houses and gives more free rolls of the dice. Did the AI try this along the way?

It's more exciting, but unlikely. Humans aren't exactly dumb, so to be beaten by something that actually is VERY dumb, is pretty hard. AIs that beat humans usually do so by having an inherent "AI" advantage. Like being able to simulate millions of turns in seconds or just having wikipedia and thousands more websites memorized (to win Jeapordy) or just being able to consistently have several hundreds precise actions per minute (in videogames)... And they can even end up with minor flaws which simply didn't cause a losing problem but any human would quickly realize there is potential for optimization. I've seen an AI play Starcraft 2 and there is a number indicating the best number of units to gather resources. The AI always produced more. But it never lost because of it, so this trait survived.

Did we really need an AI to tell us that owning property after the Most Frequented Location on the Board (Jail) is the winning strategy? I guess you can’t underestimate the power of human competition. A single human would take thousands of years to get to the best strategy. But is would seem human competition leads to huge leaps in learning and strategy.

A strategy that he doesn't get into but I think important is house purchasing. The payouts always jump at the third house. If you own two monopolies, you should build one set to three houses each then the other to three houses each before building a fourth house on any.

As someone who beat my parents and way too many friends, I can say without a doubt that this AI smart. It took me awhile to figure out how OP orange properties and especially trains are. Not paying for jail is always a good idea, because jail is protection afterall for up to three turns, you have immunity to being charged a fortune from your competitors properties.
Adrian Pugh

i naturally always tried to grab all or most of the trains. Its cool to see that Ai picked up on that trains its clever and makes it harder for ppl to get by without paying either for the train or property next to it.

As a person who has put an extensive amount of time into playing Monopoly quite competitively, I found this extremely compelling. I would like to ask a few questions, though: Can the AI build houses or perform trades at any time? That is, is there a separate "building/trading" phase after each turn? The official Monopoly rules do allow for this, and it's extremely important for strategy. Can I know more details of how the AI played? I would like to see examples of trades it made, for example. Would it be possible to have a human player play against this AI? Even if it's done with a primitive or even text-based UI, I would love to either play solo against 3 AI or have a group of the world's best Monopoly players play against one AI.

@Jotarozee Orange is the strongest but realistically with good trading most properties are equally viable if the trades are balanced properly.

@Jotarozee It's hard to define my entire strategy because it's extremely complex. Monopoly is a very complex game where every situation is unique. Generally, you want to use your actions to maximize your leverage and use your leverage in trade deals with other players to try to gain as much power within the game as possible to make it as likely as possible to win the game.

Did the AI have the ability to create a strategy which adopted different behaviour at different stages of the game? i.e.: Paying to get out of jail is better early, when there's still lots of property to buy, but to stay in jail rolling later, when it's best to stay put and collect? Mortgaging properties as a priority to be first to 3 houses per property / 4 houses to block opponents later / hotels when blocking is no longer viable end-game? Over-indexing on railways and utiities early game, but underindexing on their important in late game? Monopoly is about having a playstyle which changes as the game progresses... I'm hoping the AI was flexible enough to do that?

I don't understand his "pay off debt to the bank" comment. Too many jokes make it hard to understand what's going on. Since you start with $1500 you can't buy anything for $3000, unless you can borrow from the bank?

I did a similar experimental a few years ago, trading was a huge pain to implement. Early on in learning I would just watch hundreds of trade offers go back and forth (usually the same deal but for 1/2 dollars more or less haha) I ended up limiting trade offers heavily in the number that could be made
