SUDOKU 75

The magic of numbers in Sudoku, like the magic of letters in a crossword puzzle, makes you spend time with the puzzle until it is completely solved. There are as many as 75 options for filling the playing field with numbers. At the pre-launch stage, you can choose the task you want to solve. They are placed in the list in ascending order of difficulty: from simple to complex.

We remind you of the rules of Sudoku, it makes sense to read them if you are getting acquainted with a puzzle of this type for the first time. So, the playing field is divided into 9 squares of 3 in rows and 3 in columns. Each of the squares contains 9 cells-cells-containers for numbers. Thus, there are 81 cells in total in the field. At the start, some containers already have numbers in them and you can't change them during the game. This is the so-called binding. During the game, you must fill all the cells with numbers without exception so that the numbers are not repeated in any small square, in any large column, or in any large row. That is, each small square must contain the entire set from 1 to 9, and the numbers must also be placed in rows and columns.

The puzzle is considered solved if you have followed the above rules exactly, and there is not a single empty cell left on the field. It is clear that the fewer numbers in the binding, the more difficult Sudoku in general. Such options are shifted to the end here (numbers 51-75). Good luck and have a good logical rest!
