It’s been a while since I last posted a Weekend Special puzzle. This time it’s a Flower Sudoku in Jigsaw Sudoku format. Or Jigsaw Sudoku in Flower Sudoku format? I don’t know. There was one Jigsaw Flower Sudoku variant posted a couple of years ago. The puzzle for today is rated COOL. Make sure to […]

Twodoku

By djape | Published: March 11, 2012
Here we go… another “classic” Sudoku that I can’t remember posting before. Twodoku is a Gattai-2 puzzle, which means that there are two overlapping Sudokus. It’s a tough one, I think. In order to solve it, you should use all classic Sudoku solving techniques, but it would help if you also knew how to apply […]

Butterfly Sudoku

By djape | Published: February 20, 2012
I realized that I never posted a classic Butterfly Sudoku puzzle on the main page of the website. A few of them have been posted on the Daily Sudoku Variants page, but the puzzles posted there disappear from this website after a week. So… to rectify this issue, I am presenting you with a Butterfly […]

Jigsaw Sudoku in Flower Sudoku format (5 in 1 Gattai-5)

By djape | Published: April 26, 2010
This should be a tough one – perhaps too tough? It’s only rated “BRAIN”, but the layout makes it quite difficult, I think. 5 overlapping Jigsaw Sudoku puzzles put together in the Flower Sudoku (Gattai-5) layout, which is similar to Samurai Sudoku but not exactly the same. Make sure to use the “Twin Nonets” solving […]

Butterfly Killer Sudoku X

By djape | Published: September 21, 2006
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)

By djape | Published: July 28, 2006
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 […]
