Today we have Erica created for Scojo's prompt, as redeemed by aqjhs, to create an Escape The Grid Full Rank puzzle, ideally using one constraint :-)
It is around 3* according to testers (thank you), but since Full Rank is not a standard variant, I am posting it at 4*, and I believe some might find it even harder.
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply in the main 9x9 grid.
Full Rank: The digits on columns and rows, read in both directions, make a total of 36 numbers of nine digits each. Cells outside the grid have a value equal to the rank for the indicated row/column among those 36 numbers, where the lowest is 1 and the highest is 36.
German whisper: Cells inside the grid have value equal to their digit. Adjacent values along a green line have a difference of at least 5.
If you liked this puzzle, I recommend trying out my other puzzles :-)Lösungscode: The number in rank 14 (9 digits).

Beautiful puzzle! Very nice interactions between the ranks and the German whispers lines. I have solved a few Full Rank puzzles before but this one still felt like 4*.

Was a fun solve. Can't trust those testers. ;)
SK: Thank you for testing and a nice comment! I can trust the testers and I really appreciate the tests, but I was not sure between 4* and 5*, and due to testers saying it's 3*, I posted it at 4*. I had people solving my 3* puzzles saying they usually solve only 1* and 2*, but they like the series and wanted to give it a go. This puzzle is way harder than all 3* in this series, so I had to post it at 4*. I hope it checks out :-)

Very hard deductions and especially tough mid/end solve for me, but still a great puzzle :D
