A-Sums Sudoku
(Published on 1. November 2020, 17:35 by ICHTUES)
- Each main diagonal cannot contain a repeated digit.
- Box 5 is a magic-box (sums of columns, rows and diagonals are equal).
- Clues outside the grid indicate the sum of the digits placed before digit A in the respective row or column. Digit A is constant, if the clue has the same colour. So there are 3 different A's (black, green and blue). It is part of solving to find the value of A.
Solution code: row 4 and row 5

This is a really nice idea for a rule set. The wording on the A-Sum restriction is a little ambiguous though, which I think may be scaring people off from solving it. If I may suggest a rewording:
Clues outside the grid are A-Sums. The first digits in the clue's row or column must sum to the number in the clue. All A-Sums of the same colour are followed by the same digit. Each colour's A-Sum digit is different.
Then there could be an example image that shows two black sums and a green sum, to demonstrate how it works.
Very enjoyable puzzle. I look forward to trying your other A-Sum sudoku.

The solution code is Rows 4 and 5.
The german version is fine, but the english version misses out row 5.
