    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…

    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

    This is a game I wrote over the last month and a bit. The effort allocation was pretty different from what I've done in the past. The game design snapped together very quickly: I had the initial idea, played a couple of games on a spreadsheet to get a feel for the idea, and made one change based on those plays. After that everything felt just right through multiple rounds of playtesting. Likewise the puzzle generation is nowhere near as elaborate as in my previous game, fairly simple methods worked well and provided good variety. Instead I ended up spending silly amounts of time on curating…

    Hey folks, wanted to share my new logic game I created. I hope you'll enjoy it. It looks easy, but it's only illusion. The goal is to make 210 points on all levels: easy - doable, medium - not sure, hard - I'm happy when I make over 80...

    I've been playing Wordle and remembered this puzzle game I used to play with my grandfather. It's inspired by the block puzzles in many newspapers but made to be shorter: just guess the nine letter word. So I made a quick thing to play with my family like we used to. I thought you guys might enjoy it.
