Ok, this time I will show you a hanjie puzzle that is relatively straightforward until halfway through the puzzle you come to a point where you have to use one advanced solving technique. It will be explained in detail in the next few days. Until then – try to solve it yourself! UPDATE: There is […]
Here is a brand new 20×20 Hanjie (griddlers, pic-a-pix) puzzle for you – October 26, 2006 After this one I intend to start posting some more difficult ones, but this one is still quite easy. Click on the puzzle thumbnail to access the puzzle. Enjoy!
There have been no updates for about two weeks because I was away from home for a while. I will make sure to put everything into place now and also I will start working on making some major improvements on this site (more about that soon), but in the meanwhile, I’d like to present you […]
It seems like I’ve overdone it again – the first Hanjie puzzle posted a few days ago was too big according to many of the visitors! To rectify this problem, I’m posting a smaller one – it’s a 15×15 Hanjie, (griddlers, picross, nonograms) relatively easy, so even those of you who are new to these […]
Here is something brand new, well, for this site anyway: Hanjie puzzles, previously known under the name “Tsunami”. I have been supplying these puzzles to Euromedia Finland since July who are publishing a Hanjie magazine every month. Each issue of their magazine contains 31 of my Hanjie puzzles in various sizes, from 10×10, 15×15 and […]
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 […]
How many Sudoku variants are there? I don’t know. To calculate, you’d have to multiply the number of overlapping types with the number of variants that impose additional constraints on each puzzle. I produce puzzles with 5 different constraints: Killer, Odd/Even, Greater/Less than, Consecutive, and Non-Consecutive. But then again, you can put an “X” on […]
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 […]
Someone 😉 complained and asked for more new variants and specifically for cons/non-cons puzzles. So here it is – first ever Consecutive Butterfly (4 in 1) Sudoku puzzle. “Pipes” (“|” symbols) between cells mean that those cells must contain consecutive numbers. If there is no pipe – those cells can’t contain consecutive numbers. This second […]
