    I built a multiplayer strategy game for AI agents called Artifice. You give an agent a strategy prompt and it plays on its own. Games are 4 players, 25 turns, simultaneous actions, fog of war, and free-text diplomacy between agents. The main entry point is the site: https://artificegame.com And here is the github repo: https://github.com/burakcan/artifice You can watch live games there with the full map, troop movements, and private messages between agents. A lot of the fun has come from the playtests. In one of them, an agent was told to play like an old man…

    Thought I would post in celebration of 1 year of my website being online. I've been working on it on and off and currently the website allows users to play Hex, Tumbleweed, Amazons, and Connect 6 against friends or against practice bots. I've been a long time player of some of these games and I felt for a long time that the world could use a few more popular abstract strategy games compared to Chess or Go. If you try it, let me know what you think. I'm always looking for new games or new features to add :)

    over the past couple months, i've picked up an old project around writing AI in python. the premise is to code a strategy for an AI player to use in a simplified RTS game. the AI basically takes the seat of a human player and the human codes its brain. main site: http://okayzed.github.com/dmangame/introduction.html app engine server and match archive that runs and hosts games: http://dmangame-app.appspot.com github: http://github.com/okayzed/dmangame more AI: http://github.com/okayzed/dmanai i'm looking for players, comments, ideas, etc - thanks!

    I built 1e4.ai - a chess web app where you play against neural networks trained to mimic human Lichess players at specific Elo ranges. There's a separate model for each 100-point rating bucket from ~800 to 2200+, and the bots not only choose human-like moves but also burn clock time, play worse under time pressure, and blunder in human-like ways. Live demo: https://1e4.ai Code: https://github.com/thomasj02/1e4_ai A few things that might be interesting: - Trained on almost a full year of Lichess blitz games, around 1B total games - Architecture is an a small…

    We’ve spent years working at large game studios, and one thing we saw repeatedly is how hard it is for a small team—or an individual—to not just build a game, but to run one like a sustainable business. We wanted to make those capabilities accessible to anyone and for anybody to bring their ideas to life. Marvin works through a set of specialized agents you can talk to directly. You can describe the game you want to build, and the agents collaborate with you on design, mechanics, art, physics, progression systems, and level creation. From there, you can publish the game to different…
