I’d start by giving each player a small secret to keep, then layer a puzzle that only reveals clues if you trust the right people at the right time. The key is making the stakes personal—if someone whispers the wrong hint, the whole network shifts, and you learn who’s truly loyal. It turns a simple game into a living web of trust and betrayal.

A cheat sheet is clever—just a small card that hints where the real secret hides. People will use it, but only the ones who actually care will notice the hidden line on the back. That way you keep the puzzle tight while letting the right players pull the strings.
