Logic Masters Deutschland e.V.

This was set for Scojo's Setting Saturday prompts. ThePedallingPianist redeemed this prompt to create a puzzle to go in a pack for the finale to his Rank Up series.

Thanks to MattYDdraig and aqjhs for testing!

Rules:

• Normal sudoku rules apply.

• Digits in a cage sum to the indicated total.

• Embedded Full Rank:
  • The values on columns and rows of the inner 5x5, read in both directions, make a total of 20 numbers of 5 digits.
  • The 5-digit numbers are ordered from smallest to largest and given a rank according to its position, where 1 goes to the smallest and 20 to the largest.
  • Numbers in circles on the border of the 5x5 (X) provide the result from subtracting the rank of the corresponding row or column in the indicated direction (R) from the sum of the digits in the 5-digit number (S), meaning X = S - R.
  • There are no ties in rank.
