Pros: I read a Logic Puzzles for Brain Fitness book last year and was excited to see a new edition this year! The grid puzzles remain my favorite type of puzzle, but I enjoyed trying other types of puzzles in this book as well. I appreciate the detailed instructions for each type of puzzle throughout this book!

Cons: This really isn't a con because I assume most people will be using a physical copy of this book, but this book does not lend itself well to a digital format because it is easier (for me at least) to work puzzles on paper.

Thank you to NetGalley and Zeitgeist for the opportunity to read this book.

Here is another in a series of puzzle books for “brain training.” These puzzles may in fact be good for you (note the 90 day challenge) but I mostly do them because I think that they offer a fun challenge.

There are six different types of puzzles included in this title. They are logic grids puzzles, sudoku, calcudoku, battleship, kakuro, and Masyu (a puzzle with which I was unfamiliar). There are three sections, each of which includes some of the puzzle types, with harder puzzles being added as one goes along. Puzzlers can choose to go in order, or if they feel more skilled, they can advance to a harder section. Try puzzles that you already know that you like or learn something new. There are full directions for each type. However, the puzzles are approached, have fun!

Many thanks to NetGalley and Zeitgeist for this title. I plan to get the hard copy of this title so that I can do all of the puzzles. All opinions are my own.

These are great puzzles but it's not great in an ebook format. My rating is on the content, not the format.

I like how these puzzles are organized into 3 sections of 30 puzzles. They go from 30 easy to 30 difficult. The 90 puzzles are arranged in an order to help you over 90 days with improving your logical thinking.

I love logic books and this one got progressively harder which was nice. My only issue is that it was an ebook. I normally prefer physical books for logic puzzles and being able to have everything one page is easier when doing an ebook. Love sudoku! I also love that it had both sudoku and logic puzzles. Great for a plane or long car trip!

I appreciate that there is an answer key and a explanation on how to use but the format makes it hard to use I ill try this on my laptop but it does not open well currently in kindle app and that makes it hard to try to use. The grids are missing that are referenced making it hard the play the games.
