The rules don’t mention it at the moment, but I assume the circles are supposed to be odd (like in the odd/even Sudoku last week), since the puzzle doesn’t seem to work otherwise.
Yes, either it is surprising that it is not mentioned, or one is expected to deduce that. Nonetheless, nice breakin there across the bottom row and 3rd col.
Great fun!
Sometimes I solve one of the puzzles from this site and wonder if some aspect of the solution was intentional. I think I’m just going to assume that yes, it’s intentional, always. Fun solve.
I love the checkerboard pattern, not only was it aesthetically pleasing, but it also lent itself to some fun logic. Thank you for the wonderful puzzle!
I feel like I would have gone the other way and marked all the even digits instead of all the odd digits when constructing this puzzle, for aesthetic reasons.
Nevertheless, nice easy puzzle.
