Sudoku 1.0.0

Sudoku is a classic puzzle with numbers. The playing field consists of 81 cells divided into smaller squares with a side of 3 cells.

There are some numbers from 1 to 9 in the squares at the beginning of the game, and the player needs to fill in the free cells with numbers from 1 to 9 so that in each row, in each column and in each small 3x3 square, each digit would occur only once.

There is a table of records, as well as several levels of difficulty.
