Sudoku
PuzzleWorks on a phone
Play Sudoku online, from easy to evil. Pencil marks, undo, and a hint when one cell refuses to budge, and the rest of the grid is still waiting on you.
Every row, column, and box wants 1 through 9 exactly once. A clash lights up when two of the same digit share a line.
Easy is a clean solve. Hard, expert, and evil are there when you want the grid to fight back.
How to play
Pick easy, medium, hard, expert, or evil. Tap a cell and press 1 to 9, or use the number pad. Notes toggles pencil marks, Undo steps back, and Hint fills the selected cell.
