The game provides a great mental exercise and is suitable for beginners as well as advanced level players. You can play the Classic Sudoku game in four levels of difficulty, ranging from easy, medium, hard, and expert level games. While this may sound simplistic, playing the game can be quite a challenge as only a few numbers are spread out as hints and the player needs to figure out the rest by matching them as per the rules of non-repetition of numbers for any row, column, or sub-grid. The entire grid is broken down into 9 subgrids, with each subgrid having 9 boxes to be filled with numbers from 1 to 9 each.

The Classic Sudoku game is played in a 9x9 grid, in which each row and column of the grid must carry numbers from 1 to 9 without any repetitions.
