Twin Nonets
Lets formalize the technique that can be used when solving overlapping puzzles, which I have been referring to as “the new solving technique” and that I now call Twin Nonets. Basically, this technique is a sub-technique (or if you like – a consequence) of the naked/hidden triplets technique that you are all probably aware of. […]

More Swordfish
I posted another classic Sudoku that requires Swordfish/X-Wing solving technique. You should practice this technique because at some stage I might post a Killer Sudoku that will require you to use this technique to solve the puzzle. Maybe. 🙂 Of course I also posted another Killer – it’s a Brain X. Have fun.

However, I ran my generator and generated a couple of thousands Killer Sudokus and NONE of them required Swordfish, just as I speculated before. […]

Subtraction combo
Udosuk, one of our visitors who is most active in giving hints for the puzzles we post here, has made a suggestion for a new solving technique for Killer Puzzles. He calls it “subtraction combo”. I’m posting his explanation here (slightly modified): I’m proposing a trick which I think many players already knew, but I’ll […]
Puzzle difficulty
First of all, I posted a Killer X puzzle rated THINKER for today. I would like to know how difficult you find this one. Regarding the INSANE puzzle posted on Friday – I see that there has been a lot of discussion regarding it’s difficulty and the difficulty of some other puzzles posted last week. […]

Cage Splitting – Killer Sudoku
Ok, here is the explanation of the “Cage/fence splitting” solving technique for Killer Sudoku puzzles that I promised before. I will use the puzzle posted on Friday, October 7 and solve it step by step using this method. We extend the idea of the “innies” and “outies” solving technique, except that you’re not looking for […]
