This was set for Scojo's Setting Saturday prompts. I redeemed this prompt to create a puzzle that highlights the interaction between sum dots and another constraint.
Thanks to ChinStrap, Manta-Ray, and ThePedallingPianist for testing!
Rules:
- Normal sudoku rules apply.
- Digits in a cage do no repeat and sum to the value in the upper left corner.
- Digits in cells touching a gold Sum Dot must sum to the indicated total.
- Two cells with the same color circle contain the same digit.
- The sum of the four cells along a black circle is the same for all black circles.
Solution code: Column 5 top to bottom

Very nice! What is so astounding for me is that you come up with beautiful mathy puzzles that only have one working solution. Exceptional setting. Thanks
MG: Thank you so much for solving and enjoying so many of my math related puzzles lately! If you haven’t already tried it, I highly recommend 000MAM, it might be my best puzzle!
