TeeTotal Sudoku
Inspiration for this variant comes from Sudoku Surprise Test by David McNeill.
Solve online in Penpa+ (You can draw T's using Line mode and Middle sub. You can switch between Line and Sudoku modes using Tab button; thanks Nick Smirnov!)
Place the digits from 1 to 8 and a letter T in each row, column and 3×3 box. The letter T can be orientated in any of the 4 horizontal or vertical directions. In addition, the digits in the 3 cells immediately adjacent to the arms of the letter T must add to the same total for each letter T.
Solution code: Row 5, followed by column 5.

@Eisbär: Try T instead of 9.

@Rollo, pin7guin Nein, alle Ts haben die gleiche Summe. Für die fehlenden Ts muß es also mindestens eine Orientierung geben, bei der die Summe paßt.

@pin7guin: Nein, sondern für jedes T mit derselben Orientierung. Z.B. können die Summen für Z5S3 und Z6S6 verschieden sein.

Also: "für jedes T" :-)

Ziffer = Buchstabe.

Ich verstehe 'für jede Ziffer T' nicht, T ist doch keine Ziffer. Ist damit gemeint 'für jede Orientierung'?
