Products that do what Dimity Jones in Puzzle Castle: An Electronic Escape Novel does

_Dimity Jones In Puzzle Castle: An Electronic Escape Novel in Eighty-Nine Ciphertexts_ is a (mostly) fictional story, contained in a single text file, that requires the reader to solve puzzles as they go along, and to use each chapter's solution as a key to decipher the next. Think: escape room in the form of a novel. A computer, and rudimentary coding skills in a language of your choice, will be indispensable for performing the transformations -- and might help with the solving too! My wife, the author, passed away five years ago. This is not the last thing she wrote, but it is the most…

    This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…

    It's a web app that uses AI to turn any book into a playable text adventure. Your favorite book, but your choices, hence your story. You can even "remix" the genre like playing Dune as a noir detective story. Note: Work in progress. Suggestions are welcome.

    A while ago I discovered three.js, a JavaScript library to manipulate 3D objects. It looked really interesting, but I had no real need for it... To change that I recently challenged myself to make one 3D web game per month with three.js. And I just release game #2, a puzzle game called Cuboid, and you can try it here: https://www.thomasfriday.com/cuboid/ Please let me know if you have any questions or feedback. Thanks!

    I’ve been working on a unique storybook designed to teach kids about how computers work, and I would love to get your feedback. Set 500 years in the future, the story follows two kids – one a robot, the other a human – as they explore the workings of what to them is ancient technology: our present-day computers. I’ve aimed to keep each story short and engaging, sprinkling in humor and illustrations to captivate young readers. As an open-source project, you’re also welcome to check out the source here: https://github.com/yong/lostlanguageofthemachines

    Wordle reminded me of Mastermind, a game I played as kid, so just for fun I made a version of the game that plays a lot more like Mastermind. I think this version is way more challenging :)

    Hey HN, Michael and Scott here. We’re open-sourcing an interactive murder mystery featuring LLM-driven character agents. Solve the mystery by finding clues, taking notes, and interrogating agents. They all have distinct motives, personality, and can impact the game in different ways (attacking you, running away, etc). Try it out, it’s pretty fun! We’re also open-sourcing the framework that we used to make and refine the agents. The goal is to create an intuitive interface for storytellers to create, debug, and test game agents. We then take those game agents and expose an API beyond just…

    This is an idea I’ve been kicking around for a long time, and I decided to finally code it up. In the same way that Scrabble decomposes words into letters, what if there was a game that decomposed letters into sub-shapes? There’s a lot of directions this could go, and I’m still exploring the possibility space. Enjoy. Suggestions welcome. It doesn’t have a real name yet.
