Erbsenzähler (with sujoyku)

(Published on 22. October 2024, 15:44 by SamuPiano)

This is another collaboration with sujoyku! As always, it was an absolute pleasure to work on this, and we are very happy with the logic that we came up with in this one.

The title is German and, literally translated, it means “Pea Counter” (describing a person that is overly precise). We wish you happy solving!

Rules:
Sudoku: Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
Split Peas: The sum of the digits on a line strictly between two circles is equal to a concatenation of the two values in the circles, in some order. For instance, 3_346_1 could be a valid split pea line, as 3+4+6=13, which is 1 concatenated with 3.
Counting Circles: A circled digit indicates exactly how many circles contain that digit. Note: This also includes all circles which are bounding the split pea lines. If, for example, a 3 appears in a circle, then there must be exactly 3 circles that contain a 3.

Very nice and very approachable! (Two stars at most, I think.) Split peas turn out to be a fine vegetable for the Sudoku community. Thank you very much for creating and sharing this snack.

Amazing puzzle! What a coincidence to publish a puzzle with almost identical ruleset as mine..Though this puzzle had a different break-in from my puzzle. Thanks for the puzzle!
