Insane Killer Sudoku

Ok, a few regular readers have requested an INSANE Killer Sudoku puzzle so I had to respond. This puzzle should be very difficult to solve. In fact, it might require some trial&error attempts to be solved. Do not attempt to solve this puzzle unless you are willing to accept that! Click on the puzzle thumbnail […]

Daily Consecutive/Non-consecutive puzzles

Well, it’ time to revive the “Daily Sudoku variants” page. First of all, that page has been renamed to “(Non)consecutive”. Since this variation of Sudoku puzzles has proven to be more popular than odd/even and greater/less than, I have decided to give you one such puzzle every day, Monday to Friday. Hardest puzzles (IQ/Insane) will […]

First INSANE September 27 anniversary

Well, folks, one year has passed since I posted my first INSANE Killer Sudoku puzzle. Although it wasn’t “perfect” (it contains singleton cages), most probably this site wouldn’t become popular if it hadn’t been for that puzzle. It was by far the most difficult Killer Sudoku puzzle that the world had seen at that time […]

Sudoku Killer Insane – with Quad Symmetry

I just uploaded an INSANE Killer puzzle to Daily Killer page. Not only that it has the highest difficulty ranking, but it’s also fully symmetrical, just like yesterday’s BRAIN puzzle. Normally, Sudoku Killer puzzles have “rotational” (or diagonal) symmetry, but I have enhanced my generator to create puzzles with any symmetry – rotational, horizontal, vertical, […]

Daily & Weekly Puzzles

Since it seems that this week’s brain X was a tricky one, today I didn’t post an INSANE puzzle, but rather just an IQ. It’s still quite difficult – maybe even more difficult than the brain X. I also posted a 4×4 classic Sudoku puzzle with another “shape” in it. It looks pretty I think. […]
