    Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess. OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in…

    Hello, HN! Figure is a little side project I’ve been working on. Someone described it as Bejeweled meets Wordle. I built the puzzle interface and website in Next.js and React, which was a first for me and overall a great learning experience. The daily puzzle data is queued up in a PostgreSQL table. Another table stores anonymous solve stats. Once a day, a cron job hits a serverless API that promotes the next puzzle as “live” and prompts Next.js to update the prebaked static site with the new data. The game state is managed with Redux and your stats are persisted to localStorage. Framer…

    Hello HN, I've created a new Sudoku app for iOS and Android that prioritizes simplicity and privacy. It's free to download and use, and I'd be grateful for any feedback or suggestions. Features: > 4 difficulty levels, accessible at any time > No personal data collection of any kind > Clean, minimalistic design that focuses on the game > Takes up significantly less space than other popular apps (by a factor of about 10x) > Minimal use of advertisements I was frustrated by how many of the popular Sudoku apps feel excessively over-engineered, consume a lot of storage space and some that even…

    It's like a mix between Picross (Nonograms) and Polyominoes. It's a minimalist puzzler which has no text, no tutorials (none required) and no ads set in a relaxing environment. App Store: https://itunes.apple.com/gb/app/shapeuku-shape-puzzle-game/i... Play Store: https://play.google.com/store/apps/details?id=com.dtbgames.s... I have a bulk load of Android promo codes to give away, so if you'd like one let me know! (Sorry iOS users, I have no free codes left!)

    Hey HN, About twenty years ago, while I was in college, I first stumbled upon James Propp's Self-Referential Aptitude Test [1] and absolutely loved it. Ever since then, I've had this idea of turning that concept into a daily game, and I've finally built it: https://www.logiquiz.com/ The game interface checks each question against the answers you've given, so it doesn't spoil anything by giving away the answers. There are five different tests each day, from very easy to very hard. I'd love to hear what you think! [1]: https://faculty.uml.edu/jpropp/srat-Q.txt

    Well HN, I've finally produced something I think is worthy of sharing, but I didn't do it "in a weekend". Yeah, it's an iOS puzzle game. And yeah, it's a game I built because I wanted to play it rather than based on market research, so all this sort of makes it the antithesis of a popular HN post. But whatever. Still hoping for some of that patented (har har) expert HN feedback. Critique any part of it except the music. Also, PM me for upgrade codes, or I can post some here if there's any interest. Download (it's free):…
