Yes or No - Detective Game

Play original yes-or-no detective riddles you won’t find anywhere else. Perfect tabletop and road trip party game for friends, couples, kids and family!

A friend witnessed something impossible.

You’re at the scene. You can interrogate the witness… but they will answer ONLY with: “Yes”, “No”, or “Irrelevant”.

That’s how Case Files begins — a detective party game of short mysteries you solve through questions, deduction, and teamwork.

HOW TO PLAY 1. Pick a Host. 2. The Host chooses a case and reads the setup. 3. Everyone else asks yes/no questions to uncover the full story. 4. Connect clues, test theories, and crack the case.
