10!

Normal Sudoku rules apply. Place the digits 1-9 in each row, column and box without repetition. Killer: Digits in cages must sum to the number in the top left corner of the cage. Digits may not repeat within a cage. Sum Line: Box borders split blue lines into sections, and the digits on those sections must sum to the same value. If a line has multiple sections within a box, these sections are summed separately. Each individual section’s total is equal to one of the killer cages total.
