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

I’ve been working on a puzzle game for a few years as a side project. The game is based on a small region of tiles in a grid that is mirrored, modified, and mirrored again. It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…

I’ve been building a few small games to help kids (and curious adults) build reasoning and logic skills. Think Word Ladder, Prime Hunter, Math Maze ,all in the browser, no installs. Would love feedback or suggestions for new types of puzzles

I built a daily puzzle where a piece of paper is folded and hole-punched, and you predict where all the holes end up when it's unfolded. It's the kind of thing I used to do in grade school with actual paper and scissors, and it turns out the mental version is a surprisingly good spatial reasoning challenge. Three difficulties each day: easy is a 4×4 grid with one fold, hard is 6×6 with three folds. It's built with Next.js. The puzzles are generated deterministically on the fly using a daily seed. The engine runs a forward simulation of the paper folds using 2D coordinate mirroring, then…
