Fill in the grid so that each zone is filled with as many unique numbers as there are cells in the zone.
Hence the numbers from 1 to 3 in a three cell zone, from 1 to 4 in a four cell zone, etc.
Cells in the grid with the same numbers cannot touch each other. Not vertically, not horizontally and not diagonally.
There is only one valid solution!
Available in all grid sizes (square or rectangular) between 5x5 and 15x15 and in different levels of difficulty from easy to very difficult.
