    Pure Sudoku – No ads, no lives, no nonsense

    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…

    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! 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…
