This puzzle has a special meaning to me. I'm incredibly grateful that I found the passion for solving and setting puzzles.
This is not thanks to myself. But on the one hand the CtC YouTube channel, which introduced me to this wonderful world, and on the other hand this fantastic community.
The inspiration, encouragement and wonderfully pleasant atmosphere within the community is something I would never want to be without again.

This puzzle is an attempt to appropriately say "thank you". Thanks to everyone who is part of this great community!
I would be happy if you just read this. I hope, however, that the puzzle can give you a little more pleasure. Have fun!

Rules:

Sudoku: Fill every row, column and 3x3 box with the digits 1-9.

Cryptic/Differenz dots: Each of the letters T, H, A, N, K, Y, O and U corresponds to one of the digits 1-8 and all of them have to be different. If a letter is placed in the top left corner of a cell this cell has to contain the corresponding digit. If a letter is placed in a dot between two cells the difference between those cells have to match the value the letter corresponds to. Empty dots as well as different colors are only for aesthetical purposes and have no further meaning.
