Mystery night: how to play lateral thinking puzzles at home

Lateral thinking puzzles are one of the very few games that need no board, no cards and no preparation: just a story, a group of friends and an appetite for interrogation. Here's how to run a mystery night that requires nothing but a table.

What you need

Almost nothing: 3 to 8 people is the sweet spot, dim lights help the mood, and someone has to play the "narrator", the one who knows the solution and answers everyone's questions only with "yes", "no" and "doesn't matter".

The narrator problem

This is where most game nights stumble: the narrator doesn't get to play. They know the solution, so they lose all the joy of the hunt. On top of that, they must judge every borderline question correctly ("does that count as a yes or a partially?"), which is genuinely hard.

The fix: one phone in the middle of the table

On PlayWhydunit the narrator's chair is taken by an AI Game Master that knows every fact of the story and never bends the rules for anyone. Open a story on one phone, put it in the middle, and the group asks in turns: nobody sits out, everybody plays, and the referee is neutral. The story can be read aloud (there's narration at one tap) and the hunt begins.

House rules that work

• Round-robin: one question each, in order, so the loudest voice doesn't monopolise the table.
• Think out loud: before asking, say what you're thinking; the group builds on each other's ideas.
• Whoever cracks it picks the next story.
• Start at 2 difficulty stars and climb; the 5-star ones are for veterans.

And when the night ends…

…the game carries on solo: everyone can play from their own phone whenever they like, take on the Mystery of the Day and watch their place on the leaderboard. The next game night is much easier to arrange once everyone's hooked.
