Prime Sudoku

A set of Sudoku puzzles of varying difficulty awaits you in the game Prime Sudoku. You can choose from four options: easy, medium, difficult and expert. The more difficult the task, the fewer numbers will appear on the field initially. When filling the cells with numbers, keep in mind that they should not be repeated either in columns or rows, or in the 3x3 squares that make up the playing field. Select numbers on the right side of the panel. If the set number is not valid, it will turn red. Enjoy your favorite Prime Sudoku puzzle.
