The Object Bluff Challenge

Two people sit shoulder to shoulder, with a small object between them so neither can see what the other is holding.

Each person holds a real object. One of them says what they have (like, “I have a pen”), but they might be bluffing.

The opponent asks follow-up questions about the object. The fun and challenge come from the liar needing to answer clearly to sound believable, while the opponent tries to ask tricky questions to catch the lie.
