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
One of our visitors (Phyllis) asked about the puzzle posted on October 13. Now, this puzzle definitely doesn’t need any trial and error to be solved – in fact it’s only rated as “thinker”. However, it requires a technique that in the new version of Perfect Sudoku will be called “complex innies/outies”. It is basically […]

I will use the puzzle posted on Friday, October 7 and solve it step by step using this method.

Killer Sudoku – September 27th
Many people have asked about the Killer Sudoku posted on September 27th. I haven’t tried to solve this Killer by hand but it is very much possible that it requires either a lot of math (the technique that I call “cage/fence splitting”, which will be explained in the next few days) or that it cannot […]

The Rule of 45 of Killer Sudoku (innies and outies)
This tip is probably the most important solving technique of Killer Sudoku, one that will save you a lot of time. It does involve some math, but very simple one. Basically, the whole story is that you have to bear in mind that 1+2+3+4+5+6+7+8+9 = 45. Very smart, huh? Well, maybe not so, but it’s […]
