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 third "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 box where the "2" is. This only
leaves the square that is highlighted green.
