What is OffChess?

OffChess is an offline chess puzzle application designed for players who want to improve their tactical skills without requiring an internet connection. The app provides access to a library of over 100,000 chess puzzles that can be solved anywhere—during commutes, flights, or other situations where connectivity is unavailable. The application features a rating system where users gain and lose points based on both their performance and each puzzle's difficulty rating, allowing players to track their progress over time. This mechanic helps identify strengths and weaknesses in puzzle-solving ability. OffChess includes multiple customizable board themes, enabling users to personalize their solving experience to their preferences. Built by the developer of rdx, a privacy-focused Reddit client, OffChess prioritizes user privacy and operates without advertisements. The project is open source, making it accessible to anyone interested in chess puzzle training. The app addresses a specific use case: providing productive chess training in situations where internet access is limited or unreliable, allowing dedicated players to use downtime effectively for skill development. OffChess is suitable for chess enthusiasts of all levels seeking a distraction-free way to practice tactical puzzles offline.
