What this site is
SudokuPath publishes Sudoku puzzles you can play in a browser, print on paper, or use to learn the game. Everything is free and nothing needs an account.
How the puzzles are made
There is no puzzle database. Each grid is generated on your own device at the moment you ask for it: a complete solution is built first, then numbers are removed one at a time, and after every removal the puzzle is checked for two things — that exactly one solution remains, and that it can still be solved by a named technique rather than by trial and error.
Difficulty is measured by the cost of that solving path, not by how many numbers the grid starts with. It is the honest measure, and it is why an easy puzzle here really can be finished by scanning and an expert one really will need a wing or a fish.
Privacy by construction
Because puzzles are generated in your browser, nothing about your solving needs to be sent anywhere. Your current grid, your times and your daily streak live in your browser's own storage. We could not see them if we wanted to. See the privacy policy for the full detail, including what advertising does involve.
How it is paid for
Advertising, placed so it never sits between you and the board: no unit inside the grid, none between the buttons, and nothing at all on a printed page.
