                  To the right is
an example of a partial Sudoku puzzle. Using only the given
information, there is a way for you to locate the position of a "1" on
the grid. Can you figure it out? Move your mouse over the puzzle to
reveal the answer. The correct position will be highlighted in green.

             Step-by-Step Explanation: 
             
             
            
              
                
                  1. Look at where
the first two "1"s are located. You can't place a "1" in the first row
because
there is already a "1" in that row. In addition, you can't place a "1"
in the second row for the same reason. The first two rows are darkened
because a "1" can't go in either row.

                  2. Look at where
the last two "1"s are located. You can't place a "1" in the first
column because
there is already a "1" in that column. In addition, you can't place a
"1"
in the second column for the same reason. Those two columns are
darkened because
a "1" can't go in either column.

                  | 3. Look at the
3x3 block in the upper left corner. A "1" has to go somewhere in this
box because of the rules. The "1" can't go in any of the darkened
areas. This only
leaves the square that is highlighted green. |
