Sudoku is a logic puzzle where your task is to fill the 9x9 grid with numbers. The classic Sudoku game involves a grid of 81 squares. The grid is divided into nine blocks, each containing nine squares. Solve the Sudoku puzzle by filling in the empty cells with a single number (from all the possible candidates) that doesn't violate Sudoku rules. There is only one correct number per cell.

Complete the Sudoku puzzle so that each and every row, column, and region contains the numbers one through nine only once. Use markings to solve difficult grids or the magic wand in case you're stuck. In cases where the solution isn't immediately obvious, you markup or pencil in a vacant cell the possible candidates for future reference. Select between a daily challenge and various difficulties and the Sudoku game becomes a great mental exercise. Players of Sudoku may also be interested in learning to play Futoshiki.
