Hidden Sums
(Published on 27. November 2021, 20:19 by jwsinclair)
Normal sudoku rules apply.
Digits cannot repeat within a cage.
Every cage's sum is a two-digit number which appears somewhere within the cage in horizontally adjacent cells (e.g. if the digits in a cage sum to 27, it must contain a 2 immediately next to a 7, in that order from left to right).
No two cages have the same sum.

Tougher than I expected. Wonder if I missed something obvious ... Nice puzzle, thanks.

I find it harder than 3 stars. The killer sum logic isn't that hard (basically same as opposite arrow sum, which I've done a few), but the sudoku is pretty hard (for me, because I'm so bad at sudoku).

Fun concept and surprising quite easy (at most 3 stars) for a puzzle with little information in the grid. Thanks! :-)
