The goal of Sudoku is to fill in a 9×9 grid with
digits so that each column, row, and 3×3 section
contain the numbers between 1 to 9. At the
beginning of the game, the 9×9 grid will have
some of the squares filled in. Your job is to use
logic to fill in the missing digits and complete the
grid. Don’t forget, a move is incorrect if:
• Any row contains more than one of the same
number from 1 to 9
• Any column contains more than one of the
same number from 1 to 9
• Any 3×3 grid contains more than one of the
same number from 1 to 9
Sudoku Tips
Sudoku is a fun puzzle game once you get the
hang of it. At the same time, learning to play
Sudoku can be a bit intimidating for beginners.
So, if you are a complete beginner, here are a
few Sudoku tips that you can use to improve
your Sudoku skills.
• Tip 1: Look for rows, columns of 3×3 sections
that contain 5 or more numbers. Work through
the remaining empty cells, trying the numbers
that have not been used. In many cases, you
will find numbers that can only be placed in one
position considering the other numbers that are
already in its row, column, and 3×3 grid.
• Tip 2: Break the grid up visually into 3 columns
and 3 rows. Each large column will have 3, 3×3
grids and each row will have 3, 3×3 grids. Now,
look for columns or grids that have 2 of the
same number. Logically, there must be a 3rd
copy of the same number in the only remaining
9-cell section. Look at each of the remaining 9
positions and see if you can find the location of
the missing number.
