Favorite Source for Logic Puzzles
September 18, 2018 5:32 PM   Subscribe

We have a sudden mania for logic puzzles in our house! What are your favorite sources for logic puzzles? (Online, print, whatever.) I would double extra love a site with a "logic puzzle of the day" (or even week) that I could put in my RSS reader. A range of difficulties would be great.

The New York Times updates its puzzle page daily. If you scroll down past the crossword, you'll find 4 logic games: Spelling Bee, Sudoku, Ken Ken, and Set. Each of those has multiple skill levels within as well.

I liked the battleship puzzle in this FPP. The thread has a couple of other suggestions.

If the NYT versions of Set and KenKen aren't enough: KenKen has a puzzle of the day, as does Set .

These are a little more math-y, but U Waterloo CEMC has great problems of the week you can subscribe to.

For clarification, do you mean einstein's fish sort of logic puzzles or something else?
If the above is true:
Sporcle's got some good hard logic puzzles, my favorites are by katiewandering.
Otherwise, those slighly seedy looking puzzle/crossword/word jumble/acrostic newsprint books will also have a decent logic puzzle or 5 in them.
If the above is false then: *shruggo*

the 1987 computer game The Fool's Errand is full of logic puzzles and is recently-isa became playable online.
I have enjoyed revisiting it a lot.

I think I learned about TypeShift here. It’s a crossword type puzzle app that has a daily feature that gets harder throughout the week, and also other “packs” you can do.

PennyPress/Dell referenced by brujita offers a value pack of back issues that is a great bargain - far cheaper than getting the current monthly issues and, frankly, logic puzzles age very slowly.

I will nth the Penny Press / Dell logic puzzles if that is the sort you mean.

If you want things like Sudoku, KenKen, Battleships, Slitherlink, Kakuro, and the like, then krazydad.com is my favorite. There are printable versions, as well as interactive ones you can do online. I have used tons of these with kids from 3rd grade and up, and they love them. The ones relying on spatial reasoning are pretty simple for kids to pick up, and the difficulty level ranges from easy to totally fiendish.

On krazydad, there are a number of puzzle types which I have not seen other places. My favorite is Area 51, which is a hybrid of several other puzzles.

Montague Island Mysteries is a book of loosely linked logic puzzles that build up to a final whodunnit. It doesn't really deliver "the immersive pleasure of a novel," as the blurb claims, but it's an interesting experiment, and the three dozen-odd puzzles are fiendish.

This site has really good English style or maybe you know them as grid style puzzles. If you are talking about others, that same site has ton of sister sites that have lots of other formats. The anacrostics are really good.

Here's an endless fountain of puzzles.
Seconding this one and the excellent iOS app!

You might like paint by number, which is a form of logic puzzle.

Conceptis puzzles has a lot of the non-word logic puzzles. Griddlers focuses on the nonogram type (aka paint by numbers).

KrazyDad has thousands of really good logic puzzles that can be printed, downloaded, and/or done online. Sudoku, kenken, slitherlink, kakuro, and lots of other ones.

Oh man — i grew up with those Dell and PressPress logic puzzle books but haven’t thought about them in years (ok, decades). There was just something very satisfying about working through those with a pencil on paper. Pens were for machocists.

If you're interested in knights and knaves type logic puzzles, I highly highly recommend Raymond Smullyan's books, particularly What's the Name of this Book? and Alice in Puzzleland. I worked through the first of these as a pre-teen and it's amazing that it takes you from pretty simple puzzles all the way to Godel's Incompleteness Theorem.

My favorite source is Nikoli.com, but they actually closed up just a few days ago. They promise to develop a mobile app soon, and I’d recommend their puzzles for sure if they do.

The Art of Puzzles is one of my favorite puzzling sites. The Microsoft Puzzle Hunt also keeps some of their old events online here if you’re into that sort of puzzling.
