Split-Pea Production Network

(Published on 2. December 2025, 00:31 by Oddlyeven)

Rules: Normal Sudoku rules apply. Put the digits 1 to 9 once each into every row, column and box.
Lines: All lines are both Split-Pea and Product-Sum lines that share their sum, but have different end-points.
Split-Pea Lines: The sum of the digits on a line between two circles is equal to a concatenation of the two digits in the circles, in some order. For example, 3-436-1 would be a valid way of filling a split-pea line as 4 + 3 + 6 = 13 = 1 concatenated with 3.
Product-Sum Lines: The sum of the digits on a line between two squares is equal to the product of the two digits in the squares.
