Show HN: 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 it with my nephew and some friends, so here it goes.

The ask: Give it a try! Feedback is most welcome—let me know if the mystery stumps you or if you have ideas for future cases!

I'm also more than happy to answer any questions about how I put this project together, e.g., the tech stack used.

Thank you very much for stopping by and taking a look.

Cheers Diana
