WasmBots – A WebAssembly-powered programming game
I've been working on a browser-based programming game where you write bots to explore procedurally generated dungeons in any WebAssembly-compatible language. It's like a minimalist roguelike where your character's brain is a program you write. There are pre-made libraries for C, Rust, Zig, Go, and AssemblyScript. The game mechanics are intentionally simple for now, but the challenge comes from building up your bot's understanding of the world from limited local information. Your code needs to handle mapping, pathfinding, and strategy while dealing with monsters and potentially hostile other…
What it does
In the maker’s words, at launch
I've been working on a browser-based programming game where you write bots to explore procedurally generated dungeons in any WebAssembly-compatible language. It's like a minimalist roguelike where your character's brain is a program you write. There are pre-made libraries for C, Rust, Zig, Go, and AssemblyScript. The game mechanics are intentionally simple for now, but the challenge comes from building up your bot's understanding of the world from limited local information. Your code needs to handle mapping, pathfinding, and strategy while dealing with monsters and potentially hostile other players. Some interesting technical bits: * Pure WebAssembly modules with no JavaScript dependencies (not even using wasm-bindgen for Rust) * Cross-language development with native debugging support via language-specific trainer builds * Custom messaging protocol implemented across the five example languages using code generation The project started as a way for me to poke around WebAssembly, especially exploring its potential as a universal plug-in language. There were a lot of yaks to be shaved as I went, though, and I ended up also learning a bunch about various build systems, roguelike exploration mechanics, procedural generation, etc. It's been a fun experience so far and I feel like it's hit a nice point (decently polished presentation of bots exploring the dungeon) before I start the next phase of adding actual game mechanics.

A few months ago (82 days to be exact!) I posted a link on HN to my game, Meatshields. A bunch of you commented and played my game and gave me some wonderful feedback. Over the last few months I've been playing with many of you and implementing the best of everybody's suggestions. So, thank you, HN for all your help! I feel this is an extreme overhaul I couldn't have done without your input. Since then, I have: Dramatically improved our hosting platform (So it HOPEFULLY won't go down this time (oops.)), Added two new units, Rebalanced all existing units, Added many more maps, Improved the…

I hereby present my little tiny pet project that entertained me for the past six months. In this post, I briefly present Maginet and its technical components. It is a turn-based strategy game that is built using Rust and compiles to WebAssembly with HTML5 bindings, which works on mobile and desktop alike! It comes with many game mechanics and components, including an AI opponent and online cross-platform multiplayer. There is so much to discuss even for a project of a smaller scale, but I am nevertheless excited to share a little bit about how you can actually build a game in Rust,…
- CACoderoulette, a pair programming game for developers2016 · ▲42
Hello everyone, We just launched a side-project we have been building over the last couple of months -- Coderoulette is a pair programming game for developers, like a Chatroulette for hackers. We match developers in real time and give them coding challenges they have to solve doing pair programming using a collaborative IDE and video conference. You can check it out here: https://www.coderoulette.com/ We also published an article explaining how we built it. I'd love to hear your feedback.…
- RRReel Rogue – A browser roguelike (idler) about manipulating the oddsJan 2026 · alt-qq.com · ▲6
About a month ago, I shared the Day 1 prototype of this project (https://news.ycombinator.com/item?id=46448670). It has since evolved into a somewhat more polished "Slot-Machine Deckbuilder." I also recently moved the project from qq-pwn.com to alt-qq.com. I did this mid-development specifically to see if I could migrate a live player base and session states without losing people. The Design Challenge: The core of the game is a "One-Armed Bandit" dungeon crawler. The challenge is balancing the "house always wins" nature of slots with the player agency required for a good…

http://codewords.io/ I've been trying to get permission to run a game of it from the publisher and designer (CGE & Vlaada Chvátil) but I haven't heard back. I've found demonstrating that there's interest in what you're doing is the best way to get ahold of people. So.. Anyone interested in trying a massive game of Codenames over Twitch? Not quite "For Science!" more "For Engineering!" Which, let's be honest here, has a much better ring to it. If you'd like to know more, I put up an FAQ up here: http://codewords.io/faq/ If you'd like to sign up to help,…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…
