Sudoku Standard Game

Want to play the most ordinary version of the Sudoku board game? Then go to "Sudoku Standard" and start playing another classic version of the puzzle game, without all the contrivances, new rules and abstruse counters. The usual rules are waiting for you, without any hints. The game has only 2 modes, normal and difficult. They differ only in the number of initially added numbers on the playing field. If you want simpler, choose the medium mode. In front of you, as always, a square field with 81 cells, in which you must place the numbers that are in the block next to you. The basic rules are the same. One column, row and mini-square must not contain the same digits.
