Hello.

I recently made Counting Secrets, which uses this exact ruleset. After seeing Dorlir's Supersquish Dominoes featured on Cracking the Cryptic, I wanted to see what would happen with a similar idea in a 9×9 grid.

Normal sudoku rules apply.

Counting circles: A digit in a circle indicates how many times that digit must appear in circles.

Each counting circle is the center of a 3×3 area which contains 9 unique digits. (The circle on the edge of the grid only reaches 6 cells.)

Digits separated by an X sum to 10.

Have fun.
