Balanced Sum (Hyperbolic Sudoku)
(Published on 12. December 2024, 09:56 by MonsieurTRISTE)
Rules:
1. (Hyperbolic Sudoku) Fill the grid with 4 selected digits from 1-9 so that no digits repeat in any row or box. The solver must deduce which 4 digits are selected. A "box" is a 2x2 square and a "row" is 4-cells-long and slightly folded at box edges.
2. (Balanced Sum) Every set of 5 rotationally symmetric cells sum to the same number.
3. Digits on an arrow sum to the digit in the arrow's circle.
Play on Penpa Note: When you play on penpa, the arrows are "deformed". Please switch to "Number" mode and turn on "Draw on Edges", and fill all digits in the right middle of cells in order to trigger the solution check. Enjoy!

Solution code: All the "outer" digits, starting from the circle of the longer arrow and going clockwise. (15 digits in total, no spaces.)

I would say it was definitely a 4-star. Had to do some math to figure out which digit went where and what relations digits have with each other. Wonderful puzzle-math problem
