Lateral-thinking riddles reward the question nobody else thought to ask. I love watching a room chase complicated theories for five minutes before one quiet person notices the tiny assumption holding the whole mystery together.
How to Play Yes or No Riddles
One person reads the situation and secretly checks the answer. Everyone else may ask questions that can be answered with yes, no, or irrelevant until the group reconstructs what happened.
Do not add facts that are absent from the solution, and give a small hint when players are stuck on an unimportant detail. The goal is a satisfying click, not a three-hour hearing about whether the carpet was beige.

How to Host a Better Lateral-Thinking Round
Choose six situations and give the group three minutes for each. Answer only the question asked, and avoid volunteering the key fact too early, because the fun is watching players discover which assumption deserves to be dismantled.
When someone solves it, ask that person to retell the complete explanation in one sentence. This prevents a lucky keyword from ending the round before everyone understands why the answer works.
