24 alternatives to Mongo Murder Mystery – Can You Find Out Whodunnit?
What: So I built this small (and ofc free) web-based interactive game where folks solve a murder mystery while learning MongoDB commands and concepts. It combines a fun storyline with practical lessons to help you practice querying and navigating data. It’s not a full tutorial—more like a self-directed exercise with an optional walkthrough to guide you. Motivation: Over the holidays, I wanted to teach MongoDB basics to my 8th-grade nephew in an interactive and exciting way. I was inspired by the popular SQL Murder Mystery and thought, “Why not create something similar for MongoDB?” I tested…

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)…

Hey HN! I'm excited to show off this really fun project I put together. I originally built this project 2-3 years ago, AI was already booming at the time, however voice AI agents were still very early. I loved my proof of concept at the time, but wasn't quite happy with it. I recently had the desire to check out the tech again, and know many of you will be interested. Interviews are speech to speech with OpenAI's gpt-realtime-2.1 over WebRTC. This model is... expensive, and because of that, I have to add some amount of restrictions, conversations are tied to a authenticated Clerk user id. I…

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…

Hey there! I'm the brains behind the math crossword game on my site. This game is all about making math a little more fun – users just drag and drop numbers to fill in the blanks and move on to the next level if they get it right. Let me know if face any issues or have any suggestions! :)

Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

So a while ago I was thinking it would be neat to build a site that had the most absolute utility. The idea I came up with was a site to store those little protips that are super useful, if you know them ahead of time. I hired a guy to work on it with me, and ClueDB was born: http://cluedb.com/ Please give it a whirl (it uses Twitter auth as login but doesn't tweet anything) and tell me what you think! (Various trivia: My first try at a project coded by someone else and "product managed" by me. Runs on Flask + MongoDB. Also, this is totally unrelated to my startup.)
