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 […]

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”! […]

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 […]
