      I also think that it should be 3 stars. Lovely puzzle!

      Interesting to see the difficulty ratings. 24 min for me would make it 1 *, but I needed two restarts for that as I completely messed it up in attempts 1 and 2. kind of Schrödinger puzzle: 1 and 3 stars at the same time.

      Really enjoyed this! 3* for me as well. Loved the symmetry, thanks for sharing :)

      I clearly missed something, because this was not 2* for me, but I still thoroughly enjoyed my solve path.

      I guess I missed something, but it took me a good while to get this done. The break in was nice and got it pretty quickly, but working out how the symmetry works was a real challenge.

      I'd rate this 3*, but like I said I probably missed something obvious.

      Elegantly set, thanks!

      Really about as good as a 2* killer gets. Nice setting. Very enjoyable solve. Bravo.

      Very nice! By solvetime just under 3 stars. A fun puzzle for everyone to try, thanks

      Good one. The puzzle link doesn't include the name.

      I liked it a lot, but the difficulty is probably only two stars. I did it under 20 minutes - and while I'm pretty proficient with Killer Sudokus - I sometimes take longer for one stars.
