Sudoku is a logic-based number placement puzzle. The objective
is to fill a 9×9 grid so that each column, each row, and each of
the nine 3×3 boxes contains the digits from 1 to 9, only one time
each (that is, exclusively). The puzzle setter provides a partially
completed grid. Completed Sudoku puzzles are a type of Latin
square, with an additional constraint on the contents of individual
regions. Leonhard Euler is sometimes incorrectly cited as the
source of the puzzle, based on his work with Latin squares. The
modern puzzle was invented by an American architect, Howard Garns,
in 1979 and published by Dell Magazines under the name "Number
Place". It became popular in Japan in 1986, after it was published
by Nikoli and given the name Sudoku, meaning single number. It
became an international hit in 2005.

SOLVING DIRECTIONS: To solve the puzzle below, place a
number in each box so that each row across, each column down, and
each small 9-box square within the larger diagram (there are nine
of these) will contain every number from 1 through 9. No number may
appear more than once in any row, column, or smaller 9-box square.
Working with the numbers already given as a guide, complete each
with the missing numbers that will lead to the correct
solution.
CORRECT COORDINATES: The coordinates listed are not the
correct ones. The letters along the top and the numbers along the
side are not a part of the puzzle. They are there for you to enter
the correct numbers below for the coordinates to the final, i.e.
A6=1, G4=9.
