Almost Sudoku
(Published on 5. September 2021, 12:10 by Genomico)
The first puzzle of this new variant was called
Doubles Sudoku, but at the WCPN we decided to call it Almost Sudoku. I think it has a very nice logic way of solving it, so I hope you'll like it too :) If you get stuck, the hint given at the first puzzle might help you.
Rules: Place the digits 1-9 exactly once in each 3x3 block.
In row N and column N digit N must be placed twice, while the other digits appear at most once in that row or
column. (For example, in row 5 and column 5 the 5 is placed twice, together with seven other, distinct digits.)
The puzzle is also available on
Penpa. You can use the empty cells at the right and bottom for notes (e.g. to note which number is absent in that row or column).
Solution code: Rows 4 and 6

Why does an "Almost Sudoku" puzzle carry a sudoku tag? ;)
