The goal of Sudoku is to fill the 9x9 playing field (each row, column and 3x3 block) with numbers from 1 to 9. The basic rules of Sudoku are: - vertical numbers should not be repeated; - numbers should not be duplicated horizontally; - a number can appear in a 3x3 square only once. For difficult levels, the game has built-in notes that greatly simplify the process of finding candidate numbers in cells.
