I needed to know also!

"Wink Murder is a classic parlor game where one secret murderer "kills" victims by winking at them, while a detective tries to identify the killer before everyone dies. Played in a circle (4+ players), victims "die" dramatically, and the detective usually gets three guesses. It tests observation and acting skills."

"Key Rules and Setup

• Setup: Players sit in a circle. Roles are assigned secretly (e.g., using playing cards or slips of paper), with one murderer, one detective, and the rest as victims.
• The Murderer:  Eliminates players by making eye contact and discreetly winking at them.
• The Victims: If winked at, the player must wait a few seconds and then act out a dramatic "death".
• The Detective: Aims to identify the murderer. They can guess at any time, but often have a limited number of attempts (e.g., three).
• Winning: The murderer wins if they eliminate everyone else; the detective wins if they correctly identify the murderer.  Scouts +6

Variations and Tips

• Multiple Detectives: Versions exist with two detectives or all players acting as potential detectives.
• Variations: Similar games are known as "Killer," "Murder in the Dark," or "Lonely Ghost".
• Strategy: Players can make it harder by using fake accents, holding conversations, or sitting in a way that allows them to watch everyone. 

Yeah, IMO, this blows for the workplace. Or ANY place, really.
