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 "1" is located. You can't place a "1" in that row
because
there is already a "1" in that row. The first row is darkened
because a "1" can't go in that row.
2. Look at where
the second "1" is located. You can't place a "1" in that
column because
there is already a "1" in that column. That column is
darkened because
a "1" can't go in that 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, and it obviously can't go in the boxes where the "2," "3" and
"4"
are. This only
leaves the square that is highlighted green.
