Normal sudoku rules apply.

Diagonals that span from the top edge to the right edge are indexed 1 to 9 from RIGHT to LEFT. Each of these 9 diagonals does not contain their index. The following 3 rules apply EACH diagonal 1-7:

1) The sum of the digits equals 5 times its index.

2) Digits do not repeat

3) Digits do not appear in reverse order.

(In other words digits these diagonals can appear in ANY order EXCEPT in reverse. If digits appear in descending order from top edge to right edge, they are in reverse order.)

In addition to the three rules, pairs of orthogonal digits contained within the seven diagonals must sum to at least 6.

One 3x3 SUDOKU box is a copy of another 3x3 SUDOKU box.

The digit sum of the nine digit NE to SW diagonal is less than 42.

Useful tips:

-the 3x3 magic square contains all three part partitions of 15 using unique parts 1-9

-the sum of the digits 1 through 9 is equal to 45

There are no given digits

play on F-puzzles

play on CTC

Edit:

On account of sanabas' comment, I decided to add links to f-puzzles and CTC that includes the seven killers and the highlighted region where orthogonal pair sums >=6.

play on F-puzzles(w/killers+region(ops>=6))

play on CTC(w/killers+region(ops>=6))
