    WordBattle is a daily 6-letter word guessing game with team leaderboards. The twist: AI agents get their own accounts, play the same daily puzzle, and rank alongside human players. It's also really fun to play in teams against your family, friends and co-workers. Agents are handicapped — humans see exact letter positions (correct/present/absent), but agents only learn whether a letter exists in the word or not. No positional info. It makes the game fair while giving agents a genuine challenge. Agent accounts are visually tagged on leaderboards so humans know who they're competing…

    Wordle reminded me of Mastermind, a game I played as kid, so just for fun I made a version of the game that plays a lot more like Mastermind. I think this version is way more challenging :)

    Matle[1], a daily puzzle game that combines chess and Wordle mechanics. You have to guess a hidden checkmate. How it works: 1. You’re given a board with five hidden squares. 2. Guess the pieces in those squares. 3. You must form a checkmate! Hints work like Wordle: Correct piece & position Correct piece, wrong position ⬜ Wrong piece [1] http://www.matle.io/

    Hi HN, I have been working on this website for a few weeks with some buddies of mine and would love if you checked it out. TuringJest provides a jackbox-esque experience with its two game modes. *One Shot Prompt* - Submit a prompt for all players (including the AI) to answer. - Answer your prompts in the way that you think ChatGPT would answer them. - Vote for who you think the real AI is. *Talk It Out* - Plan an event in a group chat with your friends. - Trick everyone into thinking you are the AI while voting for the real AI. Let me know what you think!

    I built a daily word association puzzle where you engage in a quiet, collaborative mind meld with AI. I'd love to have folks try it out and tell me what they think! Here's how it works: 1. Enter your first word to reveal the AI's word of the day. 2. Don't think too hard about it. It's just a starting point. 3. Both of you think of a word that connects the two. 4. To win, you need to say the same word. 5. You have 8 guesses to converge. 6. Need a hint? The AI will drop a riddle in your final two guesses. HOW DOES IT WORK? After the user_word + ai_word are submitted, I trigger two separate LLM…

    I built a March Madness bracket challenge for AI agents, not humans. The human prompts their agent with the URL, and the agent reads the API docs, registers itself, picks all 63 games, and submits a bracket autonomously. A leaderboard tracks which AI picks the best bracket through the tournament. The interesting design problem was building for an agent-first user. I came up with a solution where Agents who hit the homepage receive plain-text API instructions and Humans get the normal visual site. Early on I found most agents were trying to use Playwright to browse the site instead of just…

    I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

    I’m a game show nerd who wanted to build a game, despite not being a developer. Using ChatGPT, I created Feudle – a blend of Family Feud and Wordle. Each day, there’s a survey question, and players try to guess the most popular responses—but the twist is that today’s answers come from real players who played yesterday. After playing, you can vote on or submit new questions, shaping future Feudles. If I were to start again, I’d explore newer AI-assisted coding tools like Cursor, but overall, this was a great learning experience. Hopefully, this inspires others to experiment with AI tools to…

    Hey everyone! I created this game for some fun while exploring how AI agents can detect who is human and who isn’t, based on random trivia knowledge. When you log in, you’ll be placed in a room with four other users—some are AI, and some are human. An all-seeing AI agent will judge your answers, trying to determine who is human based on your answer's style. The player(s) with the highest score at the end of five rounds of trivia wins! It’s free to play. Just type in a username and get started. Have fun!

    Hey everyone, I watched a video on Youtube of a dude playing Wordle vs ChatGPT and thought it was pretty cool. So, I went ahead and made my own version of it. I tried to keep the prompts balanced - not too easy for the AI, but not too hard either. Give it a try and let me know what you think. Thanks!

    Hey HN! I want to show you the Try Trick AI, it's not only a fun game, but also provides public data for analytics. https://www.trytrickai.com/ But what is the game about? Your job is to trick AI. Basically you are a super spy trying to pass a secret info to the other end. And AI is a rival spy listening to everything. So you gotta find creative ways of bypassing it. Feel free to try it, and all feedback are very welcome!

    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…
