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 […]

Hanjie Griddlers Nonograms book

By djape | Published: October 31, 2011
You may have already noticed a small book cover in the upper left corner of this website, but now, this is a proper announcement for my third book containing Hanjie puzzles. Hanjie Griddlers Nonograms: Whatever the name, it’s the same game Picross had to be dropped from the title for legal reasons. More about that […]

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 […]

Tridoku

By djape | Published: February 12, 2010
Here is a puzzle that I think deserves a lot of attention: TriDoku! It’s a great puzzle-type but for some reason it’s very rarely seen in the Sudoku world. I want to change that! Even though it may not appear obvious, there are 81 cells in this puzzle. And there are 9 nonets. Just like […]

Introducing Slitherlink (loop the loop, takegaki, fences, dotty dilemma… you name it)

By djape | Published: February 8, 2010
Another kind of puzzles that I’ve started creating recently… Slitherlink! These puzzles are also known under many different names. Slitherlink puzzles are not a Sudoku variant. They can be of any size and the rules are: 1. Connect the dots to form a single loop with no points of intersection. 2. The clues given tell […]

My first Nurikabe puzzle (a difficult one)

By djape | Published: July 20, 2009
Another addition to my portfolio of various number/logic puzzles are Nurikabe puzzles. I think these puzzles are being undeservedly somewhat neglected in the puzzle world and I intend to change that. The number of solving techniques and approaches that can be found in Nurikabe puzzles far exceeds any other puzzle type. For me it was […]
