How to Win at Monopoly and Lose All Your Friends.
Monopoly starts as a fun exciting romp, only to turn into a bitter cesspool of despair.

A little-known rule of Monopoly is that the game has exactly 32 houses and 12 hotels. Once you run out of houses, no more can be purchased until they re-enter the supply by being sold or upgraded to hotels. … The core of this strategy is to buy up as many houses as possible before anyone realizes what you’re doing, and DO NOT UPGRADE TO HOTELS to prevent people from improving their own properties.

If losing a normal game of monopoly is frustrating, losing to this strategy is excruciating, as a losing opponent essentially has no path to victory, even with lucky rolls.
