A competition game to write bots for the most efficient algo
I had an idea on a competition in a highly constrained environment: 32x32 matrix, with bots running code you write! The live site is https://kingofthegrid.com/. Each bot emulates Z80 CPU and they all get equal execution time, so the most efficient algorithm wins. Bots can move, eat, clone themselves, and most importantly, survive the competition. Each submission, leaderboard is re-calculated, such that each participant has a match against each other, and the bot that makes the most wins gets to the top. It includes includes an online in-browser IDE:…
In plain words
King of the Grid is a competitive programming game where users write Z80 assembly code for bots that compete in a 32x32 grid environment. Bots can move, eat food, and clone themselves while receiving equal CPU execution time, making algorithmic efficiency the key to winning. The platform features an in-browser IDE for writing and testing code without downloads, and automatically recalculates leaderboards as new submissions compete against each other in round-robin matches. It is designed for programmers interested in low-level optimization challenges and algorithmic competition.

It includes includes an online in-browser IDE: https://kingofthegrid.com/ide/ that way you don't even have to download anything to spitball ideas. After compiling, you can test your code in browser as well. I am also hoping for submitters to come up with ingenious ideas that would force others to re-think the strategy, etc.

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
