Normal Sudoku rules apply;
Digits may not repeat along the diagonals;
Digits within a cage or indicated by an arrow sum to the given total;
Digits along a grey renban line cannot repeat and form an unordered set of consecutive numbers (eg. 2-4-5-3);
Digits separated by a white dot are consecutive (not all white dots are given).
The light grey ellipse is cosmetic.
Solution code: Digits in row 1 (left to right) followed by the digits in row 9 (left to right)
