The only difference is that randomly generated Hanjie puzzles have a random pattern as the solution, it’s not an image of anything (unless your imagination […]

Bad news folks, I’m afraid: the Samurai Sudoku puzzle printed in the Comics section of The Washington Post on Sunday, December 27, 2009, would’ve been the last Samurai puzzle printed in this newspaper. After four years and more than 200 Samurai puzzles, they have decided to stop this feature. From the editor: “The change is […]

I have just implemented a random Hanjie puzzle generator. It generates valid Hanjie (griddlers, pic-a-pix) puzzles but with random patterns – there is no pretty picture in the end!
