Hello.
Normal sudoku rules apply.
A digit in a circle indicates how many unique digits there are to be found in the up to 9 cells that form a 3x3 area around that circled digit.

Have fun.

This broke my brain at first, but once I understood the implications everything was smooth as silk. Nice one, thanks!

Took me a moment to get on the right wave length for this constraint, but it flowed very nicely after that.
