(Published on 17. October 2025, 22:26 by timotab)

This puzzle was created by my 12-year-old son, who goes by FastSandals, for my birthday. If you solve it, I know he would love to hear what you think!
  • Normal 9x9 sudoku rules apply
  • Digits in cages sum to the number in the top left corner, without repeats
  • Digits in white circles must appear at least once in the four cells surrounding the circle
