Logic Masters Deutschland e.V.

This puzzle was made for Scojo's 2025 impostor setting challenge, where each participant prepared a puzzle in their own style and later prepared a puzzle in someone else's style to have the public compare them and guess the real setter. I made one puzzle for it and I had the honor of having MathGuy_12 make an impostor puzzle.

This is one of those puzzles, the other puzzle is "only love can save us".

But who's the real me!? (Tell us in the hidden comments. No spoilers please.)

• Normal sudoku rules apply.
• Doubler Cells:
  • Place nine doubler cells so there's exactly one in each row, column and box.
  • Each doubler will have a value of 2D, where D is the digit in the doubler cell.
  • Digits may not repeat in the doubler cells.
• Full Rank:
  • The digits on columns and rows, read in both directions, make a total of 36 nine-digit or ten-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.
  • Ranks containing a cell with a double-digit number may be ten-digits long. For right to left and bottom to top ranks, double digit numbers are read in reverse.
  • 9-digit or 10-digit numbers may have leading zeroes.
  • There are no ties in rank.
• Dutch Flat Ranks:
  • Every rank value that contains a 5 (5, 15, 25, 35) must have a 1 value directly above it, or a 9 value directly below it. It may have both, but it doesn't need both.
• Adjacent values along a green line must have a difference of at least 5.
• Values in a cage sum to the indicated total. Digits and/or values may repeat inside a cage.
