Letter Killer Sudoku
This puzzle can be solved using logic only. For learning purposes I have written the first few logical steps in case you solved the puzzle with guessing.
Solve online in F-Puzzles or CtC-app (thx Nick Smirnov!)
Place the digits from 1 to 9 in every row, column and 3x3-block. Each of the letters A-F corresponds to a distinct digit from 0 to 9. A question mark replaces a single digit from 0 to 9.The numbers (encoded by letters and question marks), on the top-left corner of a dotted outlined area are equal to the sum of this area's digits. No digit can repeat within such an area.
Solution code: Row 1, followed by column 2.

Ganz tolles Rätsel und am Ende leichter als meine Steuererklärung.

Sehr schön! Ich bin allerdings immer neugierig, ob Richard auch Sudokus erschaffen kann, die ich nicht zunächst mindestens zweimal zum Widerspruch führe. ;-)))

@WAW: T&E steht für trial and error, also Versuch und Irrtum ;)
