Microsoft Sudoku is a puzzle game using numbers and a 9x9 grid. The goal is to fill the whole grid with numbers ranging from 1 to 9 using each number only once on each row, each column and in each block of 3x3 squares. Some numbers are already set and you will not be able to change them. Choose a number from the list on the edge of the board and select a box to enter that number in the grid. To help you memorize a location more easily or to avoid planning a grid with duplicate numbers, you can use notes to place on the game board. Microsoft Sudoku offers two game modes, classic and irregular and 4 difficulty levels for each.
