Normal Sudoku rules apply. Each row, column, and 3x3 box contains each number from 1 to 9 exactly once.
Killer Sudoku rules apply. The sum of all numbers in a cage (marked with dashed lines) must match the small number printed in its corner. No number appears more than once in a cage.
Arrow Sudoku rules apply. Digits along an arrow in the grid must sum to the digit in its circle. Digits may repeat along the arrows.
The white dots represent a difference of 1 between two neighbouring cells. NOT all possible white dots are indicated; a.k.a. no negative constraint.
The puzzle is also available online.
Solution code: Row 1 and Column 6

Sometimes in killers with this many clues I can force my way into the break-in. I'm glad I couldn't in this one. Once you realise the obvious you get a gem of a puzzle. Thanks
