CHAOS CONSTRUCTION - Divide the grid into regions of 7 cells, and place the digits 1-7 once each in every row, column, and region.
X-SUM CIRCLES - A digit in a circle counts how many cells of its region it sees in the row and column combined, including itself. Region borders obstruct vision. The number in the attached rectangle (if given) is the sum of those digits.
Solution code: Row 2, with a dash (-) to represent internal region borders.

Ah, nice. Some pretty easy starts to a region at first, then a consistent yet challenging flow.

I had great fun setting this one with you, Michael! Like I said to you: The pure elegance of gdc's original is, indeed, ridiculous.

Supper happy about that tribute. Setting for the CC theme week (for sudoku adventure) was a lot of fun and I always love CCs that are on the easier side.
I think you two did a great job with the pacing.
