Nabner Sumlines
The brief
Normal Sudoku rules apply.
All lines are "nabner" lines; ie they cannot contain repeated digits and no two digits along a line may be consecutive. Eg If a line contains a 2, there cannot be a 1 or 3 anywhere along the line.
Nabner lines are also "equal sum lines". ie The sum of the digits on a line within a particular 3x3 box must be the same for all the boxes the line passes through.
