The Best Monopoly Strategy, Tested on 300M Games [video]

(www.youtube.com)

Forty six years ago this was the second thing I ever programmed on a computer. It was a TRS-80 model 3, and initially Quick BASIC was the only software I had for it. My first project was a todo app. The second was a Monopoly simulation that just ran around the board to estimate which squares were landed on most often. It worked, and the high I got from that addicted me and kicked off a coding career. That damn computer should have come with a warning label.

It's surprising that a content creator would put this much work into a video and then use an AI narration.

Did you switch on YT auto translation by accident?

well how much work did he really put into it?

It feels like making "Where the tokens land was checked against the table published in Scientific American in 1996 (Illinois Avenue: 3.18% published, 3.19% in my simulation)." a key point of the investigation doesn't see like a human choice

They don't say what the strategy is in the comments (duh) but I seem to remember a similar study from years ago saying the optimal strategy was to always buy if you can.

Meta, but one rule I was surprised to learn: if someone doesn't buy a property when they land on it, it is immediately auctioned off by the bank.

Another interesting strategy was to not upgrade to hotels in order to create a housing crisis by using up all the houses

Many people play without the auction rule (hence, they don't even know it exists).

> I seem to remember a similar study from years ago saying the optimal strategy was to always buy if you can.

The optimal rule is a little different: don't sit on cash until a housing crisis.

Just like in a real-life business, sitting on cash that could be working for you is a bad idea.

Monopoly Junior works like this already - you MUST buy a property you land on, if you can't buy it for any reason the game ends.

It really works when playing with kids, but I noticed that the consequence of it in most games is that the player who goes first usually wins.

I thought the best Monopoly strategy was not to play.

How about a nice game of chess?

WarGames (1983)

I enjoy a monopoly variant where every property landed on causes an auction regardless of who landed on it.

So the conclusion is « buy everything even with borrowed money, but anyway it’s mostly a game of luck and even with the best strategy you’ll loose most of the time».

Not a bad model it seems, curious to test against a « I never want to die strategy », where everyone saves enough to keep playing, which is what mostly happens in real life too.

In the end, it aligns with YC and the startup model to try the all in for a project that will make you win disproportionately.

AlphaZero (Google's chess bot) famously started with no 'book knowledge' (e.g. ideas on how to play chess), instead, it learned by playing against itself many, many times over.

Has anyone done something similar to that with Monopoly? (by contrast, the technique used in this video is much more basic; it comes up with some specific rules a player will use, then has those bots play eachother)

reply
I have thought it couple of times, most recently after this video. I so want to make it since I feel all these videos tend to lack two things the zero-style would offer.

One: it would offer no human assumptions.

Two: more importantly it should and could include the trading part. (the op's video had some, but it felt really really limited from what I gathered)

It is really rare to see trading to be implemented. Yeah, it is the hard part but in competetive monopoly, it is big part.

I am yet to figure both input/output spaces for it. As soon as I figure them, I probably will do proper zero-style ai for many games.

Isn't trading always blocked? Whenever you would allow someone to build a complete Color it's better not to allow it, and whenever you also would it's only advantageous if your color is stronger than the other thus the other party should never agree.

Any other exchange becomes pointless as you won't be completing a color anyways.

reply
You seem to reason in terms of trying at all costs to block the other players, not to maximize your gain. I agree the ultimate goal is to do better than all the others, but the tactics to get there may involve temporarily favoring other players in win-win exchanges to grow quicker, or to block a third player already far ahead, etc.
reply
It'd be interesting if the strategy would change without the auction rule. I don't think I've ever played with that.
