The Law of Leftovers (LOL)
I promised to explain this technique, which applies to Jigsaw Sudoku (aka irregular blocks) puzzles, a while ago, so it’s time to keep the promise. You can find the same technique explained on various other sites, too. This technique is somewhat similar to innies/outies which is used for solving Killer Sudoku puzzles, but there is […]

KILLER Samurai
At long last, I just uploaded my first ever Killer Samurai Sudoku. As all our other puzzles – it’s PERFECT ;). Why: 1. It has one and only one solution. If you claim differently – triple check all the rules that apply. 2. This solution can be found by logic only – no trial and […]

Cage Splitting – Killer Sudoku

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 […]

4×2 Killer Sudoku!
Today’s puzzle is not the ordinary 3×3 Killer Sudoku, but rather it’s a 4×2 variant. All rules remain the same, except that there are now only 8 digits used (1-8). NOTE:Since only 8 digits are used, the sum of all boxes, rows and columns is 36! Be careful when you look for “innies” and “outies”! […]

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 […]
