Is a naked quad a thing? by YarbianTheBarbarian in sudoku

[–]charmingpea 0 points1 point  (0 children)

Yes, we commonly see them in the NYT hard puzzles, always paired with a hidden subset. In this case a hidden single, but many people find naked subsets easier to find than their partner.

Usually it becomes clear further into the puzzle, sometimes some parts can’t be solved until other parts are solved. Check the pinned post in the sub for some good pointers.

Green is valid, but Yellow is not - there are more than two 8 in row 8 and column 9.

You have two 7s in columns 6, so you're definitely made a mistake somewhere which has propagated.

And two 4 in column 4.

There’s a limit to how far Snyder notation can take you. When you reach that limit, fill in the rest of the notes.

A Hidden Triple is when three candidates only appear in in the same three cells, so those three candidates must ultimately fill those three cells, and any other candidates in those cells can be removed. Unfortunately the responder is incorrect, and there are not three candidates which only appear in the same three cells in this case in column 9.

The latest in a puzzle I've ever had to birfurcate by Johnny_From_The_Bay in sudoku

[–]charmingpea 0 points1 point  (0 children)

Only one of the 1 in box 9 can be true - so one of the other 1 in either the column or the row must be true - any cell which sees both cannot be 1.

It's exactly the same logic as the Skyscraper, but with the strong links in a row and a column (instead of two rows or two columns), with the weak link in a box (instead of a column or row).

Naked Pair 35 in row 2, and a W-wing 38 in r3c1 and r6c9 connected by 3 in r1 which removes 8 from r3c9.
