Solve whodunits with the ever-changing rules of Mystery Fluxx! (solo variant)

About Mystery Fluxx, from BoardGameGeek:

Fluxx is a card game in which the cards themselves determine the current rules of the game. By playing cards, you change numerous aspects of the game: how to draw cards, how to play cards, and even how to win. At the start of the game, each player holds three cards and on a turn a player draws one card, then plays one card. By playing cards, you can put new rules into play that change numerous aspects of the game: how many cards to draw or play, how many cards you can hold in hand or keep on the table in front of you, and (most importantly) how to win the game. In Mystery Fluxx, a slew of detectives is trying to solve the mystery by collecting clues, examining locations, finding weapons, and sussing out secrets...all without being eliminated themselves! The game's artwork, actions, and card titles allude to favorite mystery characters and plotlines, including Clue, Sherlock Holmes, Murder on the Orient Express, The Maltese Falcon, Dragnet, Columbo, Monk, Murder She Wrote, Matlock, Brooklyn Nine-Nine, investigative teams such as CSI, NCIS, and Law & Order, and teen detectives such as Scooby Doo, Nancy Drew, The Hardy Boys, Encyclopedia Brown, and the Enid Blyton characters. Mystery Fluxx features a larger-than-normal number of card types: Meta Rules, Keepers, Creepers, Goals, New Rules, Actions, Surprises, Dangers (which eliminate you for one turn), and a brand new card type: Secrets!
