Best Sudoku in Russian 2 is another variant of the classic Sudoku puzzle, which is played on a 9x9 square board. The playing surface is divided into nine identical 3 x 3 blocks with nine cells in each block. Your task is to fill all the cells on the board with numbers from 1 to 9. Each row, column and each block may contain a given number only once. Start with the row, column or block where most of the boxes will be filled. Usually there are a few areas (rows, columns and fields) at the easy level where only 3 or 4 digits are missing. Start there!
