Nampure Asobi: Free Sudoku game with essential techniques

Hello from Hitoriasobi Labo. We’re excited to introduce Nampure Asobi, a Sudoku web app that lets you enjoy puzzles from beginner to advanced levels, along with simple explanations of essential Sudoku solving techniques. For puzzle generation, we combine: py-sudoku from Timedia Peter Norvig’s constraint propagation algorithm and supplement them with AI support (Claude Code, Gemini CLI) plus triple verification systems to ensure unique solutions and consistent quality. It supports multiple languages (Japanese and English) and works responsively on any device, aiming to be a friendly companion for your solo time — whether during commutes, camping, or lunch breaks. The UI and animations are deliberately kept minimal for now, and I would be very happy to get your ideas to help improve it further. If you love Sudoku or are curious about applying AI to puzzle generation, I’d love for you to give it a try.
