I hope that you enjoy this puzzle about sums and products. Feedback is always appreciated! The rules are as follows:
Normal Sudoku rules apply. The product of the digits on the red part of a line equals the sum of the digits on the blue part of the line. Digits may repeat along lines if allowed by other rules. Cells that are a knight's move in chess away from each other are not allowed to contain identical digits.

Really good maths based sudoku . . . very challenging as you move round it but very satisfying too.

Eine schöne neue Idee. Ob das auch ohne Springerzug-Regel geht?

High five to everyone who struggled because they forgot the knight's move rule :)
