Hi HN, Matle is a daily chess puzzle inspired by Wordle. You're shown a checkmate position with 5 hidden squares, and your goal is to guess what’s on them to complete the mate. Someone kindly shared it here a few months ago before I had the chance to post it myself. I’m the creator, and wanted to share a few new features based on feedback, and hear your thoughts. You can now view the original game behind each puzzle, get explanations for why a guess isn’t checkmate, and see daily solving stats. Would love to hear what you think: https://matle.io

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…

I've been playing Wordle and remembered this puzzle game I used to play with my grandfather. It's inspired by the block puzzles in many newspapers but made to be shorter: just guess the nine letter word. So I made a quick thing to play with my family like we used to. I thought you guys might enjoy it.

Hi everybody. I occasionally make little browser-based games, and this is my latest attempt. It's not quite done, but it's quite playable (note: it does include audio): https://www.omiword.com/ This has been my occasional tinker target for ~5 years now, starting in the early days of Covid. The objective is to drag letter tiles within certain boundaries to spell four common American-English words. It hasn't got ads or anything, it's just supposed to be fun for its own sake. If people happen to like it, I might add an option for folks to make a small, one-time payment to unlock…

My friends and I love playing description games, but got tired of the same old cards - so I made a simple web app with a fresh set of prompts, and a different timer mechanic: Rather than teams taking turns, everyone sits together, and you describe only one prompt at a time. As soon as you're done you pass the phone to the player on your left, who gets a new set of prompts to choose from, and so on. After an exponential (memoryless) random amount of time, the round ends (loudly!), and whoever was holding the phone at the time loses a life for their team. It's like Hot Potato. The prompts are…

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…
