X-Count Mod 3 Sudoku
(Published on 2. May 2020, 05:21 by Timwi)
Normal sudoku rules apply.
Additionally, the digits have colors:
3, 6, 9: red
1, 4, 7: yellow
2, 5, 8: blue
Two orthogonally adjacent numbers cannot have the same color.
The clues outside the grid, when present, specify the count of numbers of a specific color among the first X numbers seen from that direction, where X is the first number seen. Note that X itself is included in the count.
For example, if the first digit in a row is a 5, and the clue on the left shows a red 2, then the first 5 digits in that row contain two red digits.
Solution code: Rows 5 and 6

Ich fand das Sudoku sehr fordernd, aber äußerst lohnend, wenn man sich durch den Anfang durchgebissen hat. Der Anfang ist recht knackig. Hat mir sehr viel Freude bereitet. Sehr schön.

Hübsche Idee und tolles Rätsel. Nach dem Einstieg ging es richtig flüssig.
