Use this software to play your favourite puzzle game. Sudoku is a logic-based, number-placement puzzle. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9 only one time each. The puzzle setter provides a partially completed grid.
At the start of a new game, Sudoku fills in a random selection of cells for you - the number of cells depends on the difficulty level you use. Click in any of the empty cells or use the arrow keys to highlight individual cells and press a number from 1 to 9 to fill in the cell. To clear a cell, press 0, Delete, or Backspace. When you have successfully completed all subgrids, the entire puzzle is highlighted until you start a new game.
As you work to complete the puzzle, you can display possible solutions inside each cell by holding the Shift key and pressing each number in turn. Repeat the process to remove individual numbers, or press a number without the Shift key to replace them with the actual number to use.
