Solution code: Please input 9 digits in column 9, then please input row by row the number of unique regions in each row e.g. if the first three rows had 3,4 and 5 unique regions the answer would be 345...... No spaces or special characters - just the 18 digits for the solution

mns: you need to consider rule 4, which means that regions can 'wrap around' from the bottom to the top, or from left to right. This makes it possible.

Could someone explain rule number 2, the one about nine contiguous regions. I don't understand how that is possible so I must misunderstand it.

Nah, forget my suggestion. I wasn't thinking straight!

That is an interesting suggestion! I will think about it

I would change the rules slightly so they say all digits must be consecutive to their adjecent neighbours that are _in the same region_.
