AI Learns Insane Monopoly Strategies

all hail the brown set, and rapidly auctioning everything, according to AI at least. 11.2 million games of self-play were used to discover the secrets of this classic game

"Buy the browns" Was this AI perhaps engineered in the 1800's

When you get jailed in the later turns
"Thank god"

As a seasoned monopoly player, the power of the brown set is one only the true connoisseurs know

Being a railroad tycoon is my go too strategy in Monopoly. You can't build property on them and are scattered so plenty of people don't see it as a threat, makes for easier trades. But when you get 3 or 4 they can be debilitating, especially if someone has the misfortune of landing on multiple in a turn.

You should make an AI that all of a sudden stands up, cusses out the other AI, and flips the board over. Keep it random.

I wanna see a full game with this AI against humans in discord.

“Buy the browns”

16th century Colonial powers: “hold up let him cook”

I always go for the browns if I roll it on my first few rounds. Building hotels early game can severely decrease the development speed of other players while increasing yours, allowing you to build more quickly than others and snatch cards that others can't afford. It won't really impact your late-game, as the hotels are cheap anyways, but can really help your early-game.
People are also keen to complete pink as their first street, while giving you the last blue you need, thinking it's a good trade-off. Especially if you can leverage early brown into early blues, you can easily steamroll everything by preventing other people to accumulate enough money to start building themselves. Blues and browns don't bankrupt, but they do slow down early on

I wish there was a little more talk about the new AI's behaviour at the end, I really seemed to enjoy seeing how it plays when it becomes as good as a human player

[jacknesbitt]

The animations were so engaging and you chose a very fun topic to explore! Thanks

I feel good knowing the AI picked the orange properties as the strongest overall set. Most of my won games were with that set, often supplemented by at least Boardwalk and if possible Park Place. IMO it's imperative to own boardwalk because one of the chance cards takes you directly to it; if you own the set and put a hotel on it, it's a ticking time bomb that has a 3/4 chance to annihilate someone in a 4 player game so building properties is a priority. You should never give up Boardwalk and always buy it if you have the opportunity to, if only to ensure you never get blown up by it and no other player suddenly takes control of half the board. The orange set on the other hand seems to have a decently high chance of people landing on it because of its distance from Go, which some chance cards put you at IIRC.

4:15 a big reason why the browns have such a high winrate is that they are a big indicator of who has come first around the board, who started the game and who has passed start the most. In a game with all greedy players these are what win you games, besides directly measuring who completed sets, measuring laps and total distance covered is one of the best ways to guess who gets a completed set. And also yea there are only two of them which is good

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.

One of my favorite Monopoly memories is when my younger sister bought the two lowest costing properties, built hotels on them for cheap, and then absolutely wiped the floor with the rest of us.

The animation for building the AI is incredible

[josephjackson]

The orange set is the best because it is the closest to jail and highest renting cheap property on the board.

[pabloquijadasalazar]

I love how the AI seemingly got bored and tried wild stuff like mortgaging & auctioning all its properties.

Edit: *seemingly* is the key word up there

[DARKredDOLLAR]

I love the part where AI learns to auction everything and bid nothing. This is genius.

When I used to play with my siblings, the browns were the best property on the map. We were very territorial and didn't like trading for fear of getting a bad deal or losing out, but if you got one brown, you could usually persuade someone to give you the other for whatever it was they needed, as you were only matching 2 and they were successfully matching three. They got 'good' properties-- but YOU would get the cheapest properties to get houses/hotels on in the game, meaning you could massively inflate the cost of landing on one for dirt cheap and potentially cut off your siblings' access to houses/hotels while you got your foot in the door on other properties.
