Sudoku
Classic sudoku is the heart of the collection: a nine-by-nine grid, a handful of given numbers, and one simple rule to carry you to the finish. Every board here plays straight in the browser — pick one and start filling cells.
New to sudoku? Start with a gentler board and lean on the pencil-mark habit — lightly note the candidates for each empty cell, then erase them as numbers go in. The same reasoning scales all the way up to the hardest grids.
