Logic Puzzle Book for Adults Volume 1: 50 Easy to Hard Logic Grid Puzzles - The Real Brain Challenge Paperback – July 11, 2024

I love logic grids. As a 64 year old, they are much better for me to keep an active mind than something like sudoku. I work some of the puzzles with my sharp 87 year old father. The ebook version is easy to take along, but I had to print a bunch of grids myself, since we can't write in the ebook. I'd recommend the paperback version. Anyway, we've only worked a few in this book, but so far, so good.

Honestly I've done these types of puzzles for years, and I really enjoy them. But....apparently I'm not as good as I thought, because a lot of these were way, too hard for me.

Good book

Some puzzle clues don't align with the answers. I'm disappointed

I love logic puzzles and there is a good mix in this book from easy to hard. I like that the grids are large and not on the same page as the clues to make it easier to write you answers and notes. Most puzzle books give you a tiny grid. I like that there’s help with the QR code if you need it. I also like the instructions as they’re easy to follow so my kiddo was able to play with me, great purchase! They have done some updating since it has first come out so don’t pay attention to old reviews.

Of the 12 puzzles I have gone through so far at least 2 are genuinely unsolvable. They contain mistakes that either result in multiple answers or render the user incapable of distinguishing between clues.As an example I will here is an excerpt from the book.1. The color purple and the star must be input in the same step, which occurs sometime before the step with a password requiring the color green.2. We also know this step takes place sometime before the step with a password requiring the word “rabbit” (however, we do not know the color used with this word).The use of the phrase “We also know this step” in clue 2 implies that clue 2 is talking about one of the steps mentioned in clue 1 but it doesn’t clarify which step it’s talking about (whether its the step with the color purple and star or whether its the step with the color green) or it could be referring to a brand new step. This means there are at least 3 completely valid solutions to this puzzle based solely on the reader's personal interpretation of what "this step" means. Even then when you interpret it the way the writer intended you can still have multiple valid answers that meet all the criteria of the clues but doesn't match the provided answer.

I love how these logic grid puzzles make me really think — no random guessing here. The 6x9 size is super convenient to toss in my bag for trips. If I get stuck, the QR code walkthroughs are a lifesaver and explain every step clearly. Plus, the bonus tips helped me improve fast. Great for both beginners and puzzle pros!

I do logic puzzles quite a bit. I normally mix it up by doing one puzzle from easier section, then the next day do a puzzle from the more difficult section. The clues given on these puzzles ALL have to do with an ORDER, like this one must be before or after that one; this one must have one between it and the other one. ALL THE CLUES. The easier ones (front of book) are doable, but I need to resort to a spreadsheet for the harder ones in the back of the book to see all the what-if analysis. I'll continue to do them because I like a challenge, but I won't order another book from this series.
