please meet "Iraroji VOW" (Or Illulogi VOW, depending on who you ask). it's a picross game for the DS! only released in japan due to its very niche theming; it's all centered around quirky or odd photographs taken in otherwise mundane areas of Japan, that were all sent into the annual book series "VOW" or "Voice Of Wonderland". whilst there's no english translation to be found for this little thing, it's really quite a neat footnote in From Software's gameography. Seems to come with comments about the images made in the books when they first appeared; according to one site i found in research, all of them come from the first 8 or so books from the early to mid 90s.
How it is as a picross game? ehhh it's fine. The difficulty is a kind of all over the place and it immediately starts off by throwing 15x15 puzzles at you (even the early ones like the one pictured here is on a 15x15 board!) and also it commits the Picross Sin of letting you overwriting previously laid dots/crosses easily if you hold the button down and scroll the cursor from one side to the other. but on the flipside, its also still early days for picross video games, having been released way back in 2007, just a couple of months after Nintendo's first offering on the DS. Sure, there were the Mario Picross games and the BS-X titles too, but I feel like the game as a whole never really properly took off until after Picross DS and the Picross-e/S series came out. Jupiter Corp did a hell of a lot for this beloved puzzler.
Anyway, if you're after a more challenging Picross game and want something a little different - the game comes with loads more themes than the one i've pictured here - then go check out Illu-Logi VOW out some time. I hope one day this gets a translation patch so the various comments on the photos can be enjoyed, but I'd say it can all still be enjoyed quite a lot without knowing the language.
EDIT: oh and if sudoku is more your thing, they did the same thing with that puzzle instead, it's called Nanpure VOW
