Best Sudoku in Russian 2

A full 9x9 number grid sets the pace in Best Sudoku in Russian 2. Nine smaller 3x3 sections split the board, and the puzzle uses digits 1 through 9 across the entire layout. Four difficulty settings shape each round by changing how many numbers are already placed before play begins. Russian appears only in the menu and rule text.

How to play?

Fill empty cells with digits that fit the row and column around them. Each 3x3 section also allows each number only once. Work from the areas with the fewest blanks, since easy boards often leave only three or four spaces empty. Check which digits are missing, then test each empty spot against the row, the column, and the matching section. Cross off impossible placements to narrow the options. A solved board leads to medium, hard, and expert puzzles.
