These days, Sudoku has been acquiring popularity amongst high school and elementary students. It is like a magic square. Sudoku is an enjoyable math puzzle game that only requires concentration and logic. There is only one rule to solve Sudoku. You have to fill in the board so that the numbers 1-9 appear exactly once in a column, row and in a three by three box. The Sudoku is initially filled in with numbers. You should fill the empty boxes. Apply the rule above while solving the math puzzles. However, the diagonals are not considered. Remember that the initial numbers inside are to be left unchanged. Focus on the goal to fill the whole puzzle by numbers from 1-9.
