Today is the anniversary of my first published puzzle, and this is already my 35th puzzle, so I'd like to thank the amazing LMG community for all your support, comments and ratings, I really appreciate that!

Rules:

  • Normal sudoku rules apply.
  • Every cell orthogonally adjacent to a 1 must be at least a 5 and every cell orthogonally adjacent to a 9 must be at most a 5.
  • Digits within a cage must add up to the total in the corner.

Very nice! Some really nice logic. After finding some 1's and 9's it becomes really smooth, but finding them was not easy. Congratulations on your anniversary, thanks
