A note on the name: I made this puzzle on the same day I made a much easier version of the same concept which featured all 11-cages. I called that puzzle Just Once, which I guess counts as wordplay if you speak Spanish, and published it way back in Volume 76 of Artisanal Sudoku. In this one, not every cage sums to 11 (you can probably figure out why), hence Not Just Once.

Anyway, speaking of Artisanal Sudoku, that's my weekly set of puzzles that are pretty approachable by LMD standards (more so than this one, but sometimes not by much). If that sounds interesting to you, check it out!
