(Published on 24. December 2021, 05:00 by Realshaggy)
Fill the grid with digits 1 to 9 so that each digit occurs exactly once in each row, column and 3x3 box. The clues outside the grid indicate the sum of the first X digits placed in the corresponding direction, where X is equal to the first digit placed in that direction.
In these clues, even digits have been replaced by E, odd digits have been replaced by O. (Zero is even. Multi-digit clues may not start with zero.)
Solution code: Row 5, column 5.

Sehr schön! Etwas erstaunlich dass ein Rätsel mit so eingeschränkten Hinweisen ("E"/"EE") noch eindeutig lösbar ist, und sogar mit einem schönen Lösungsweg.
