You Asked For It!
As promised, I just posted a puzzle with the rating that is currently in the lead in our poll. And that, apparently, is INSANE.

Complex innies/outies – part two
I saw two comments (by Graham and David) for the puzzle posted on October 25, and I think there’s a little clarification on “complext innies/outies” that should be made here. You should look for innies/outies in more than just one row/column/nonet. This is a good example of such puzzle. See this image: Click on the […]

However, it requires a technique that in the new version of Perfect Sudoku will be called “complex innies/outies”. It is basically […]

September 27 solved!? Or…
I’ve received a possible solution for September 27 puzzle using only minor trial and error from udosuk. Here are his comments. You can also download the images that he sent: Firstly, the first pic (dk0927a.png) shows the steps I last posted which narrows R[1,2]C7 to {25} and then some more… From there I’ve worked out […]
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 […]
