How to Play
Sudoku uses a 9×9 grid divided into nine 3×3 boxes. Fill the grid so that each row, each column, and each 3×3 box contains the digits 1 through 9 exactly once. Some numbers are given as clues. Use logic and elimination to find the rest. This version lets you choose difficulty: Easy, Medium, or Hard. You can undo moves, use notes for pencil marks, and resume an unfinished game. The game runs in the browser with no login. Take your time; there is no timer unless you want to challenge yourself.
