Logic Puzzles

Since 1980, Nikoli^ has been in the business of creating many different variations of logic puzzles (such as the very popular Sudoku and Kakuro). Unfortunately, as they're stationed in Tokyo, their magazine is unavailable to most Americans.

Luckily, over the decades they've inspired quite a few people to make their own puzzles and variants, including: posted by flatluigi (12 comments total) 34 users marked this as a favorite
Simon Tatham's puzzle collection updated just a few weeks ago to include a kenken implementation and some very novel puzzles that I'd never seen prior (magnets, signposts, singles) that get mention in those four blogs.

Simon Tatham's puzzle collection is pretty damn cool, but it makes you really appreciate a good hand-made puzzle.

Yeah, I love the puzzle collection but human-crafted ones are better by far.

Entirely. The human-crafted (bespoke?) puzzles are cunning little gems, ST's puzzles are designed to crush the human soul be quite difficult. The iterations on crossword-puzzle structures are really fascinating, like with heyawake.

Don't hate on Simon Tatham's, of course they aren't as good as hand-made, but they still have some very nice puzzles in there all the same. The puzzles they call Slant and Loopy are quite excellent.

Those are both Nikoli-created puzzle types, JHarris. :)

Loopy is Slitherlink. Here's Melon's and mathgrant's puzzles of that type; it's also one of my favorites.

Slant is Gokigen Naname, but I haven't seen any handmade versions of it.

I've been a nikoli.com subscriber for several years now, and it's been well worth it for me, especially as a timewaster when terribly bored.

Nice collection of links. A favorite puzzle site of mine is PuzzlePicnic which hosts user-submitted puzzles of quite a few different genres. It also has a Java applet that allows you to play the puzzles on your computer, rather than printing them out. It usually has one new puzzle every day.

Oh, christ. Melon just posted the 200th puzzle released on his blog, and it's a doozy.
