Best Classic Sudoku is a game with the best traditions of the sudoku puzzle! The simplicity of the playing field will allow you to immerse yourself in the game, like in the good old days on paper.
You can put both simple numbers and, for convenience, small numbers-markers for the convenience of further calculation. Play in two different modes - simple and complex for more sophisticated players.
Use your computer mouse or your finger on touch devices to select the desired cell. By clicking on a cell you can put a blue full number, or by switching the mode on the keyboard (by clicking on the pencil) put a temporary small number. Your goal is to fill the playing field so that the numbers from 1 to 9 are not repeated vertically and horizontally across the entire field, and also are not repeated in square sections of 9 cells.
