One more clever variation of Sudoku
on a "standard" 9x9 grid. It contains a set of special
clue-numbers which are small numbers always placed on
the border lines between selected pairs of neighboring
cells of the grid. Each clue-number is the product of
two numbers that should be in the respective pair of the
neighboring cells just next to left and to right from
that clue-number.
For example, clue-number 12 on the line between two
neighboring cells means that possible pairs of numbers
for these cells can be from the following combinations:
2 and 6; 6 and 2; 3 and 4; or 4 and 3.
The remaining rules are as in a "standard" Sudoku, and
the object of the puzzle is to fill in the whole 9x9
grid with numbers 1 through 9 (one number per cell) so
that each horizontal line, each vertical line, and each
of the nine 3x3 squares (outlined with the bold lines)
must contain all the nine different numbers 1 through 9.
To solve the puzzle you can print just the above grid.
For this click the image of the grid to go to a new
window with this grid; then you can print it. |
