Sudoku secret that will blow your mind:

In EVERY single sudoku puzzle, the red ring and the 4 green squares have the EXACT same digits.

The proof is laid out in this video (Via Kottke)...

One of my favorite new-to-me techniques is called “the impossible rectangle”.

Since each puzzle has only a single correct answer, if you see four cells that form a rectangular shape with each other, and each cell has almost but not quite the same pairs in it, you know that one of the four cells must be something other than that pair - otherwise the puzzle would have more than one answer.

BenCurranDev,

@Kclemson have your played Good Sudoku by @helvetica ? It does so much to teach t techniques like that, I love it. I learnt how to identify an X-Wing!

@BenCurranDev @Kclemson interestingly the second example up above isn’t a unique rectangle because the 4 squares must exist in only two houses.

otherwise there could be other constraints on them being flippable that negate the technique

This took me about 40 minutes to do. Lots of branch points in it. Quite fun.

Un nouveau jeu fait son apparition sur le site FORTISSIMOTS : une variante du sudoku, appelé le « TOHU-BOHU » et proposé par un nouvel auteur, Neil Osant.
Il s'agit de placer les lettres A à I dans la grille, selon les mêmes principes qu'un sudoku, mais avec l'aide d'indices qui renseignent sur leur emplacement réel dans la grille.
Le grille n°44 n'attend plus que vous !

couchchilis,

So here’s an early sneak preview of the game we’re working on. It’ll need one more design pass, but the iOS version is almost ready. will be next.

Sudoku that is almost filled in. Numbers that are all done are de-emphasized, while mistakes become little red notes.

If you're still trying to piece together the puzzle of your St. Patrick debauchery, you might skip this post. If you like Sudoku puzzles, this one's for you! 16 unmarked number puzzle mags! These are all about 10 years old, so, even if you do these all the time, you've probably forgotten this batch by now.
