I love how the symmetry is broken by the rules and not by anything visible on the grid!

Very fun! Since I'd done your 6x6 puzzle first this was a 3* for me (well, once I remembered that this one didn't allow digits in a cage to repeat) but if I hadn't already figured out some of the tricks to how these cages work on that easier one, I suspect I would have struggled a lot more to break in. I'd love to see more of this ruleset!

Amazing that it's enough to define the entire grid. Very cool. Thanks!

I got lucky at the end of the solve, but I don't see a way to see the resolution for the last two cages.

Great puzzle! I gave it 4 stars, because of a logical oversight by me, that took me ages to find and left me at a brick wall, so actually it might be 3 stars if I had payed more attention. Thanks for the beautiful puzzle.
