Logic Masters Deutschland e.V.

Inspired by udukos's X-Sums killer sudoku #2.

Rules:

• Sudoku: Place digits 1-9 in each row, column and region exactly once.
• Full Rank: The digits on columns and rows, read in both directions, make a total of 36 nine-digit numbers. Cells outside the grid have a value equal to the rank in ascending order among those 36 numbers for the indicated column or row in the direction of the cell.
• Killer: Digits may not repeat within a cage. A double-digit clue inside of a cage prevents both of its digits from appearing anywhere else in the same cage (this means 11, 22 and 33 may not appear in a cage, and 8 and 18, for example, may not appear in the same cage). A double-digit clue may include zero.

Solve online: (No answer check)   penpa   ctc

Note that the conflict checker in ctc is a bit wrong because cells outside the grid seem to see the digits in the same row or column and I don't know how to fix this.

Enjoy!
