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…

Hi, I wanted to share a simple game I wrote. It's a sliding pieces puzzle like many others. I have focused a lot on making the experience smooth and minimalistic and the levels being challenging in a way a sudoku or chess puzzles could be. I had no prior knowledge of game development and while it feels like someone competent could build this game in a week I spent over two years and hundreds of hours to bring this game to life. My journey went through: - thinking it will be a PC game - being overwhelmed by the amount of different game frameworks - hiring an indie dev to bootstrap the game in…

Hi HN, I've been working on this Sudoku web app for the past couple of years, on and off during free weekends and afternoons. I started working on it because I was bored during COVID, and Cracking the Cryptic had just become popular on YouTube, which got me wondering how hard it could be to make a Sudoku app. The main idea is for the app to understand the constraints and know how to solve Sudoku grids (and not just be a simple Sudoku drawing/playing app). When it comes to classic Sudoku, the solver doesn't support anything more complicated than X-Wing, but it understands the…

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…

Hello! I recently wanted to learn a bit about computer vision. Initially, I wanted to build something which could solve a jigsaw puzzle, but figured I should start with something (much) simpler, so I've built this instead. This is a visual Sudoku solver which runs in the browser. It works by using OpenCV to identify and process the Sudoku grid, passing this to a simple ML model to identify the digits, and then solving the puzzle with a backtracking algorithm. The ML model was trained on the TMNIST data set using a model built with Keras, also a completely new area to me. It's far from…

We were genuinely impressed by Yann LeCun’s recent announcement about his Sudoku solver based on Energy-Based Models here: https://logicalintelligence.com/yann-lecun So we (a software engineer and prodigy mathematician) worked in the weekend to see if we can beat it and we did! If Kona solves puzzles in 313 milliseconds, we currently solve 270,000 puzzles per second! We do not know the internal mechanics behind Logical Intelligence’s system, but we are happy to share ours in the webpage there is a full description, code and also a paper published. Why people are obsessed with…
