A really neat break-in that's not too tricky, and a really nice flow to finish.

Agree with the other comments that at first I thought the puzzle was going to be out of my reach but once I got a little foothold I was able to climb the mountain. Another very fun puzzle. Probably only 88% sneaky

I was really struggling to get a good start. Lots of pencilmarks and a few digits, but than it finally clicked. From there it was a relatively smooth solve for me.

There certainly is an "ah-ha" moment in this puzzle that's meant to teach something useful for this and other irregular sudokus :)

That was my first time facing an irregular sudoku and I can say it was a lot of fun! Once I wrapped my head around the irregularities it unfolded so beautifully. Thank you very much for setting and sharing with us such a nice puzzle, it really hit the spot!

Funny you say that as this was my first time setting an irregular sudoku :) I wanted to show others what I had learned while studying the irregular layout, and I'm glad to hear that people seem to be learning the things I did!

Thank you for this fun puzzle, 99%Sneaky! It took me quite a bit to grasp the shifted regions and the placement of the quadruples. But once I understood some implications, the solve was flowing nicely. Thank you for setting and sharing!
