Sudoku Classic Game

Sudoku Classic is the simplest version of the beloved math puzzle game. You have to fill the whole playing field with correct digits, from 1 to 9. All playing field consists of 81 cells, which are divided into 9 mini squares of 9 cells. The basic rules are as follows. You have to put the digit in one or another cell so that no row, column or mini square has the same digits. The task is not easy, but if we want to solve it, the numbers and variants of their arrangement are not so much. You just need to pay attention and look carefully into the cell where you are going to put the digit. This digit should not be in the same horizontal row, vertical row and mini square. The whole game is divided into 5 modes of difficulty, namely: easy, medium, hard, expert and mad. All modes do not change the rules of the game, but only the number of initially placed digits. The harder the mode, the less digits, and the easier the mode, the more digits you have at the beginning of the game. The digits available at the beginning of the game are hints. Also in the game settings you can turn on and off automatic error checking, turn on the notes, and so on. You can also turn on and off the auto-check for errors, turn on notes, and more.
