How to play Obsession: Solo Estate Challenge

About Obsession: Upstairs, Downstairs, from BoardGameGeek:

An expansion for Obsession that introduces four new servants-the Hall Boy, Cook, Head Housemaid, and Useful Man-who can be used to mitigate Victorian Fate found in the base game. It also enables 5 and 6 players and adds the Howard family with their legendary cook. Upstairs, Downstairs includes new service and improvement tiles along with a ton of new casual and prestige guests. The expansion components empower players to screen guests, work around prestige limitations, find tiles, refresh the market more easily, and enhance favors early in the game. Finally, there are three new game modes: Solo Estate Challenge, Team Cooperative Play, and Tableau Obsession.
