Today's puzzle is by the ever-popular sudoku wizard Christoph Seeliger and it's not supposed to be too tricky. What it is is wonderfully elegant and with a tiny bit of arithmetic you can get started quickly... but can you finish?! Give the puzzle a try at the link below:

Rules:
Normal sudoku rules apply. In cages, digits sum to the small clue in the top left corner of the cage. Digits cannot repeat within a cage. In addition, each cage contains a standard "arrow" clue, which is hidden. (In an arrow clue, cells along arrow must sum to the digit in the circle from which the arrow emerges.) The 'circle' part of the arrow will be at one end of the cage with the arrow extending along the cage all the way to the other end. The circle may be any number of digits and multi-digit totals are read in the direction of the arrow.
[The rules will probably be pretty clear if you are familiar with arrow sudoku. If not, watch Simon explain the rules at the start of the video before you try the puzzle.]
