Little Killer Sudoku

Little killer sudoku

Place a digit from 1 to 9 into each of the empty squares so that each digit appears exactly once in each of the rows, columns and the nine outlined 3x3 regions.
Numbers with arrows indicate sum of the numbers in each direction.

The distinguishing feature of Little Killer Sudoku lies in the diagonal sums. Unlike traditional Sudoku, these puzzles provide hints in the form of diagonal sums. These hints are carefully calculated, ensuring that when you fill in the minimum possible digits in the arrow-direction cells, the diagonal sums add up perfectly.
