Very nice! I originally mistakenly read the rules as row, column, or box _number_, instead of position within the box. After that, and one tricky initial breakin, the puzzle was smooth and fun. Thanks!

I really liked this! Once I understood the constraint properly it went very smoothly, but still challenging enough to be enjoyable.
