The big grid consists of two partially overlapped 9x9
sub-grids. Fill in the whole grid with numbers 1 through
9 (one number per cell) so that in both 9x9 sub-grids
each horizontal line, each vertical line, and each of
their respective nine 3x3 squares (outlined with the
bold lines) must contain all the nine different numbers
1 through 9.
To solve the puzzle you may want to 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 out.
Note that you can print the puzzle for your own use only,
and not for any kind of commercial profit.
