Main Strategy

• If you rule out all of the cards removed during Setup and all the cards you can see, you will be left with 13 spaces. The solution to your mystery is among those 13 Clues.
• If a player’s answer to a question is "Zero!", you can rule out all of the cards that were asked about—no matter who asked the question—since you now know that those cards can’t be on your screen.
• A player receiving additional Magnifying Glasses usually gains no information, but they will have more actions when it is their turn: Think twice before giving a player too many Magnifying Glasses!
• Be careful when making an accusation: each wrong accusation can give away clues to the other players!
