A computer played Monopoly over 300 million times — here's the mathematically best way to win

The first player type bought everything it lands on. Another, even more aggressive, player never kept cash, mortgaging properties to buy even more. The saver, the third player type, always kept cash on hand. And the three-houses player never exceeded that number of additions to their property.

Specific player types made up the remaining players. One only wanted properties on the cheap side of the board. Another only wanted properties on the second half. A third picky player focused exclusively on railroads and utilities. And the final player bought any sort of property, but refused to ever trade them.

What it takes to win

Victory on a consistent basis was the result of players making one or more of four mistakes, Perfect Play said.

Players who are too picky about what they buy tend to lose. If you land on a property and you have the cash, buy it. Don’t want it? Another player might and that could be something you can leverage later in the game.

While hoarding cash isn’t a bad idea in this real-world economy, it’s a bad idea in Monopoly. Players who chose a strategy of liquidity over investment rarely won the game.

Housing costs might take a big bite out of your cash on hand, but you still want to max out your real estate holdings on your properties. Get to three houses fast and mortgage properties to do it if you have to.

Finally, don’t be close minded to trades with other players. Refusing to trade puts you at a disadvantage that can ultimately cost you the game.

And if you have to choose a certain property group, it said, fight for the orange properties—St. James Place, Tennessee Avenue, and New York Avenue.
