Guided Sums
This is a puzzle with a rule firstly made by Oddlyeven which you can find on the following link RSA
Rules:
Normal sudoku rules apply. A digit N on a cell with an arrow indicates that there is a straight line N cells long starting from the cell the arrow clue is on and extending in the direction of that arrow. This line acts as a region sum line: box borders divide the line into segments with the same sum. Each line must cross at least one box border.
