What is Sudoku — seeded generator & puzzle library and who is it for?
This is a Sudoku app built around a seeded puzzle generator. Puzzles are grouped by difficulty band and checked for uniqueness, so each generated grid has a single solution. A local puzzle library keeps the puzzles you generate on your own device. It suits people who play Sudoku regularly and want fresh grids rather than a fixed set. The app installs as a standalone window and works offline, so puzzles can be generated and played without a connection.
