The gap
A daily Sudoku needs puzzles that are unique, fair to solve without guessing and identical for every player on the same day, without a server.
What it is
This template generates them in the browser from the date and checks each one with a solution counter and a logic solver.
How you use it
Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.
Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.
Use it when
Built for
A cell pair is removed only if the counter still finds exactly one solution and the logic solver can still finish the grid.
The result text is built from the board state and copied with the Clipboard API, with a fallback for older browsers.
Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.
A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.
