YesNoGame and Post Mortem: situation puzzles, hosted or solo
Illustration: The Perfect Breakfast
YesNoGame is a web catalogue of situation puzzles and dark stories, built for one person to read the answer and run the game for everyone else. Post Mortem gives that job to a narrator inside the app, which also lets you investigate alone. We are LaBoîteBleue, the publisher of Post Mortem. Here is how to choose a story on YesNoGame, how to host it, and when each one fits, based on the official pages linked below.

Choosing a story on YesNoGame
YesNoGame is published in eight languages. In English you can sort the catalogue by popularity, rating, date or difficulty, filter by categories such as dark stories, detective, short or for kids, and view it as a list or a grid. Search covers titles and keywords, and the site says solution text is kept out of the results, so a search will not spoil anything.
Every story shows three figures from players who filled in a short form after solving it: the share who liked it, a difficulty out of 10 and the average solving time. Check how many people are behind them, since the page says. Some stories have hundreds of reviews, others a few dozen, and a 7/10 from twenty players is a hint rather than a measurement. Then read the statement. The time you have and how used your group is to this kind of game matter more than an average.

Hosting a YesNoGame story
YesNoGame’s rules put a presenter in charge. That person reads the answer, keeps it to themselves and replies to the group with "Yes", "No" or "It isn’t important / I don’t know / Specify the question". On the site, the answer sits on the same page as the statement, behind a Show Answer button. That shapes how you prepare.
- Open the story on the host’s phone, not on a shared screen. Once the answer is showing, one glance ruins the game.
- The host reads the answer alone before starting and makes sure they understand how the facts connect, not just the last line. They will have to rule on questions the text never covers.
- Read the statement aloud, twice if needed. Every word counts.
- Stick to the three replies. The rules let an experienced presenter add details of their own, which makes the puzzle harder, so agree beforehand whether your group wants that.
- Once the story is out, rate it. The form lets you say you already knew the answer.

What Post Mortem does differently
In Post Mortem the narrator lives in the app. You type a closed question, it answers yes, no or irrelevant, and the facts you uncover appear one by one. Nobody near you needs to know the ending, so you can investigate alone, or a group can gather round one phone with nobody sitting out as host.
Our website works like a catalogue with the answers left out. The library shows every free statement in English and French, with search, collections and difficulty, and each story has its own page you can share. The answer never appears on the web. It is in the app, where it opens once you solve the case, or straight away with the pack that contains it or with All of Post Mortem.
So if you want to host a Post Mortem story the classic way, the host needs that access before the game: they solved it themselves, or they bought access that covers it.
Which one to open tonight
If someone in your group enjoys hosting, YesNoGame gives them a catalogue, player figures to choose with and rules that fit on one page. If you are on your own, or everyone would rather investigate than keep the secret, Post Mortem was built for that: the narrator does the hosting.
We are not neutral, we make one of the two. Still, the first thing we would check is simple: who answers the questions. A long list does little for someone playing alone, and a narrator matters less when a friend loves running the game.
