Logic solvable
Derivative Arrows
Inspiration for this type comes from ___.
Solve online in Penpa+ or in Sudokupad.
Like all of my sudoku variants, this puzzle can be solved by logic alone. Guessing is not required and also no sophisticated solving techniques are necessary; just plain and easy sudoku steps and of course the intrinsic logic this specific variant has to offer. In case you don't find that logic or get stuck, feel free to ask for a hint in the comments below this puzzle and I'll be happy to help you.
Apply classic sudoku rules.
There are two arrows connected to each circle. The sum of the digits on one arrow is equal to two times N, the sum of the digits on the other arrow is equal to the square of N, where N is the digit in the circle. Which arrow has which sum is not given.
Solution code: Column 2
