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 […]
Butterfly Killer Sudoku X
It’s been a while since I last posted a Butterfly Killer, let alone one with the “X” factor. So, here it is – and to spice it up a little, I made it quite hard (altho I expect someone to get back in 20 minutes and say it was way too easy). So, you get […]

Extra special – Butterfly Killer Sudoku (hard)
Somehow butterfly puzzles have been neglected in the past few months and it’s time to rectify. A quick reminder – this breed of overlapping sudoku puzzles was suggested by udosuk and implemented by myself. There are 4 “classic” 9×9 Killer Sudoku puzzles inside this one. They all overlap and they all must be solved according […]
