Tricky Logic Puzzles for Adults: 130+ Difficult Puzzles to Challenge Your Brain

The book is titled Logic Puzzles. However, some puzzles inside rely on Trial and Error instead. I wanted to be fair and contacted the author first, but he ignored all my emails. Hints, especially the Cryptic Puzzles, just gave the final solution but noway of finding out the initial solve did I do it correctly. Once stuck, you are stuck for good. What is the point in putting a website, a Twitter, and a name when people tried to contact him and he can't even see/reply?

I’ve always loved puzzle books for that good prefrontal cortex workout, but it’s surprisingly hard to find one that focuses on actual logic puzzles without the filler of word searches or crosswords. This one hits the mark. The puzzles gradually increase in difficulty, which keeps things engaging without ever feeling overwhelming. I didn’t find any of them particularly challenging, but they were consistently fun and thoughtfully designed. The variety is impressive; I found myself enjoying everything from Nonograms and Calcudoku to the more cryptic, layered challenges. It’s clear a lot of care and creativity went into making this book.

As advertised.
