I enjoy this sort of logic puzzle: Three families with different surnames live on adjacent houses and each have a different pet. The Green family have a dog. The family that live in the middle house are not called Brown… … and so on. 1. Is there a name for this type of puzzle? 2. Anyone know of a book collection of such puzzles? Thanks! ---

You’ve answered your own question. > **[Logic puzzle | Logic grid puzzles](https://en.wikipedia.org/wiki/Logic_puzzle#Logic_grid_puzzles)** > > Another form of logic puzzle, popular among puzzle enthusiasts and available in magazines dedicated to the subject, is a format in which the set-up to a scenario is given, as well as the object (for example, determine who brought what dog to a dog show, and what breed each dog was), certain clues are given ("neither Misty nor Rex is the German Shepherd"), and then the reader fills out a matrix with the clues and attempts to deduce the solution. These are often referred to as "logic grid" puzzles.... ---

I only remember them ever being called “logic puzzles” or “loigic problems” when I’ve seen them in puzzle magazines. But of course they’re a specific type of logic puzzle. ---

There are many magazines full of them, and The USA Today even had a book of them. I think my supermarket has some in the magazine section and you can usually find them at airport newstands. ---

In Croatia, this type of logic puzzle is called “integram” for some reason. They come with a hepful matrix grid. ---

There was an old DOS game called Sherlock that was these. Apparently there’s an app version of it, now, too (search for “Everet Kaser Sherlock”). ---

That game looks interesting but sadly: - it’s from 1991 - they charge $15.99 for it Anyway I have already received two books-worth of logic grid puzzles, so I’m happy. 😀
