Fill the grid with digits 1-9 so that no digit is repeated within a row/column. Each pair of consecutive neighbors should have a line between them, forming a closed loop. All lines should be part of the loop. There cannot be any loop lines in the crossed places, and some lines may be already given. Also if there is block, it cannot contain any number but its sides can be the part of the loop.
