Normal sudoku rules apply.
Box borders divide blue lines into segments with equal sums.
Each purple line contains a set of non-repeating consecutive digits, in any order.
On green lines, adjacent digits differ by at least 5.
The negative diagonal (from r1c1 to r9c9) divides the grid into two non-overlapping parts of equal size (note: they do not include cells from the diagonal). If a digit appears N times in one part, it should also appear N times in the other part.
Solution code: Column 2 (from top to bottom)
