Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

Dear Hacker News, I'm kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance! For a limited time window, I'm setting the all-free feature flag to true. I hope you have a lot of fun exploring the AI's sense for games! Here and there, I tweaked it to help with visual consistency. I would be deeply grateful if you opted into analytics. $2,300 in API tokens... Cheers!

I built a procedurally generated word-search game where the puzzle never ends - as you scroll, the grid expands infinitely and new words appear. It’s designed to be quick to pick up, satisfying to play, and a little addictive. The core game works without an account using the pre-defined games, but signing up allows you to generate games using any topic you can think of. I’d love feedback on gameplay, performance, and whether the endless format feels engaging over time. If you try it, I’d really appreciate any bug reports or suggestions. Thanks in advance!

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…

English is my second language. From my experience, I learnt that developing your vocabulary is a long and arduous process. Traditionally, learners used flashcards (or their digital incarnations). I wanted to build something more engaging and more effective in building your vocabulary. DictionaryGames is aimed mostly at ESL (English as a Second Language) students, but I am hoping it might be fun for any English language lovers. The project is in BETA, it is free, and no registration is required. I am looking for feedback to improve it. If you comment, please indicate if you are a native…

I just finished my first iOS game, Snack Words, which is a real-time, multi-player word finding game. iTunes link: http://itunes.apple.com/us/app/snack-words/id425786167?mt=8&ls=1 YouTube video demo: http://www.youtube.com/watch?v=5zPQuqoUHqU I wanted to build something very simple and minimal. There's no figuring out who to play, and each game is only 90 seconds long. The backend is 2,400 lines (so short!) of Erlang which speaks a custom protocol (length tagged JSON packets) to the client. The Objective-C side protocol implementation makes heavy use of blocks and works a lot like my…

Hey everyone, I'm Fabio, a very long time lurker here. Today I want to celebrate and share with you, again, a game that I conceived more than 8 years ago. I shared it last week with all its history (if you're curious) [1], but it just stayed in the "shownew" and never reached the main "show" page, hopefully this time it'll do better (:crossed_fingers:)! What changed since last week? Today I've also published the mobile apps for both iOS and Android (last week it was just web), which are also my first mobile apps ever. So I believe it's still a worthwhile post and something to show :) I'd…

Hi hn, Its been a while since my kid has been dreaming to make videogames, as you know, the entry bar is high, too many technical details are involved. A few months ago, we started making games, we have tried many different ways, from dragging blocks to write code with a high-level library to make it simple, it is still too much work. Getting into the AI boat, I decided to give it a try for making games, turns out that it works super nicely, still, you still have many technical concepts involved, what language should the game be written in? where do you store the file/assets? how do you…

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…

Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!

Hi everyone! First time posting. I built this mini memory game in an attempt to beat lazy memory syndrome. because when was the last time you remembered what you did the day before purely based on memory (or without being prompted) ? Super simple fun game for giving our brains a quick workout and actually reminding it on how to remember. If you had those old Nokia phones from the early 90s, the game will seem insanely familiar to you

Hey HN, My workflow for any complex queries is to ask it in multiple AI chats (Gemini, Claude, o3,..) in parallel and then continue the conversation with the chat response that I found the most useful. I built a simple open source app that queries 10+ AI models at once and summarizes their answers with a selected combiner AI model. There's a GIF in the github repo that shows it in action. You can try it on your local machine: https://github.com/Nexarithm/multi_model_chat If you are interested, I also made a detailed blog post on technical details, feature of the personal…

Hey HN, I made conversation starter game. Here's how it works: - Choose a theme like "Couples" or "Favorites" - Tap to reveal thought-provoking questions - Take turns answering and discover new things about each other I made ConvoCards because everyone has an interesting story to tell, but these don't often come up in day to day conversations. I also enjoy using them for journaling and self reflection. I hope you enjoy playing and learn something new about someone close to you!

So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…

I'm using AI (mostly Claude) to create/publish a new video game every day This is day 33, first stab at the tower defense genre. Most of the games (including this one) I build with a single prompt. Rarely, a couple extra prompts are needed for bug fixes or to tweak the physics/UI. Extremely rarely, the AI has difficulty making the game work right (usually drawing it) and it takes a dozen or more prompts -- but the majority of the time, it gets everything right and makes a fully playable game first try Happy to answer any questions, just a little hobby project of mine I'm having…

Hi HN! We were trying to have our team adopt AI more and had the idea for "AI Bingo" - hands-on, mini challenges that resulted in something delightful and real. Our team members were obsessed, they were saying it was "weirdly addictive." People made AI-generated ASMR videos, n8n automations, games. Our email marketer built an Electron app using Claude Code. We were stunned - people were learning by doing AND having fun. So, we've spent the last few weeks building Made That, where anyone can do the same challenges and see other people's submissions. A lot of people feel a lot of existential…
