This is a remake of the puzzle the 2 towers, it is easier and has a smoother solve path. I hope you'll enjoy it

Rules:

Place the digits 1 to 9 once in every region, row and column. The regions must be found.

?: The digit (X) in the first cell next to a black question mark means that all the cells between and including that digit and the digit in the Xth position from that direction within that row or column will be in the same region, the digit in the Xth +1 has to be in a different region (Xth+2 can be in the same region). The digit in the Xth position acts like a cave clue i.e. it indicates the amount of cells it sees in its region in every orthogonal direction combined, including itself, not just those directly adjacent to it. Region boundaries block the 'vision' of this clue.

White dots separate 2 consecutive digits and 2 different regions. Not all white dots are given

the grey square is an even digit grey circle is an odd digit
