Normal Sudoku rules apply.

Digits in grey circles must be odd.

I think it's great!! Good easy puzzle to relax to.

a little bit too easy actually, and obnoxiously long solution code is certainly not justified.
[three digits are way harder to guess than the solution to the puzzle ;-)]
but it was fun.

Well, thank goodness for the copy cells button otherwise... ( •̀ - •́ )

Why not 27 or 36 digit solution code? 81 would be the best, of course read from randomly ordered rows :-)) But nice puzzle.

took me a moment to realize that the digits on the ducks must be the same instead of must be different, but once I re-read the rules it was smooth sailing.

Love the puzzle.
I’ve not put in the solution code my memory isn’t good enough to remember 18 digits
