The Logic Puzzles in this book are great for brain fitness. They start out easy and get harder and harder. They combine classic logic puzzles and soduku puzzles. As they get harder, the types of puzzles get harder as well. I love to do logic puzzles and found this to be a great activity when I need a break. I could work on my brain fitness and they were not so hard that it took much time to do. They are great and I highly recommend this. I will be purchasing a copy as well for my mother to use.

These puzzles start easy and then get harder as you go along the book. There are different long puzzles. There are word puzzles, number puzzles, and spacial puzzles trying to hit on puzzles that different things people are good at and then helping to build on the ones they aren't.. They were hard to do on teh computer lol. But I did many on paper and I enjoyed the challenge. I would absolutely buy this in-store.

Quite interesting. If you are someone who enjoys puzzles of different varieties, then this book is really fun. It has different difficulty levels as well. Time well spent!

Logic Puzzles Book for Brain Fitness is an excellent example of brain puzzles. Detailed and interesting. 4 out of 5 stars.

Super fun activity book to do to help yourself relax or pass the time. Book features a variety of puzzles that vary in difficulty. Not sure if this will help with brain fitness over 90 days. I can't see why it wouldn't, since the puzzles stimulate your brain and give you break from electronics. Many thanks for the free/gifted book @penguinrandomhouse #partner #sponsored

Thoughts: I love puzzle books. Unfortunately, the publisher sent me this one as an ebook – and it definitely does not work as an ebook. I strongly suggest you buy this book – but as a paperback one and not as a download.

Now, that being said, the few puzzles I was actually able to do were fun and well done. There are levels from easy to medium to hard with an extra section that is a mix. And, yes, there are answer keys at the back of the book. The puzzles include logic grids (for logic and reasoning), sudoku (numbers), Calcudoku (numbers and problem solving), Battleship (logical deduction, reasoning, spacial deduction), Kakuro (methodical thinking), and Masyu (visual intelligence).

Highly recommended.

This book is not what i expected in a brain teaser. While there is a variety of subject matter, the puzzles are all the same. It would be beneficial to have a scheme of different ways to solve puzzles.

This was SO HARD to read in this format. I hope that the physical book is better. I thought I would be able to see the graphs/charts to figure out the logic puzzles, but no, it was all words strung together. I tried to do the download on a regular computer and send to kindle. Both had shotty options for trying to figure out any of the puzzles.

Thank you for the copy, this is my honest opinion.

This book is great for those who love logic puzzles. Some are a bit hard to understand, but once you get the hang of it you get better.


I received a complimentary copy of this book. Opinions expressed in this review are completely my own. Thank you NetGalley and Lana Barnes for this opportunity!

This book is perfect for those who love logic puzzles! It’s set up for 90 days of increasing difficulty - 30 days of easy, medium and challenging puzzles. The grids are nice and roomy. I also like that this book includes a variety of other logic puzzles besides the traditional word / grid puzzles. Some of the others are number-based like sudoku or visual like battleship. You can work these through in order or go through them as suits your mood. Great for 90 days of mental play…or less if you’re like me and can’t resist doing more than one a day. Will it make you sharper? Who knows? I’m just enjoying myself with these puzzles.

Do you like a challenge? and do you like logic puzzles? Well if your answers are a yes then here’s a 90-day challenge for you. This book contains six types of logic puzzles including logic grid puzzles, sudoku, calcudoku, battleship, kakuro, and masyu. There’s also a helpful guide for each puzzle, if you need some help, plus an answer key in the back so you can check your work. This book also makes the perfect gift for the puzzle lover in your life.
I have to say that I had so much fun doing these puzzles myself and I think you can have some fun with them too.

I received a free copy of this book via NetGalley and I am voluntarily leaving this review.

What a fun book of puzzles! If you love logic puzzles, this book is a must have. One note, I would recommend purchasing a hard copy version, rather than an e-book, for ease of tracking as you work through to your final answer. (I reviewed an advance reader copy and all opinions are my own.)

I absolutely LOVE puzzles like this! I remember skipping ahead in math class to puzzles like these. Critical thinking, fun scenarios…this is great for a few times a day to get the brain thinking outside the box.

A good book to exercise your brain and if your brain is anything like mine, it will need a lot of stretching!! Thank you to NetGalley for letting me read this book in exchange for my honest opinion.

I love logic puzzles and this book was so fun. With six different types of puzzles for each day creating a 90 day challenge for you to enjoy. I learned to enjoy new puzzles including luckily and logic grid puzzles. Pages are clear and easy to understand. It also includes guides to help you understand how to do each kind of puzzle. The text is very clear and easy to read, which is great for me. This makes the perfect gift for all puzzle lovers.

This is an excellent 90 day challenge to help improve brain fitness and increase daily who-brain activity.

The book is divided into three sections- easy, medium, and hard. Each of these three sections contains different types of puzzles including logic grid puzzles (my favorite word based puzzles), number based puzzles like sudoku, calcudoku, and kakuro, and visual puzzles like battleship and masyu.

The book starts with instructions on how to complete each type of puzzle, so anyone knew to logic puzzles will be able to pick up the book and go.

Each puzzle is given a day number, so it's easy to keep organized.

This puzzle book is perfect for anyone who wants a daily challenge, similar to Wordle or a Crossword puzzle. The clues are easy to understand,

What an entertaining way to spend your time... while exercising your brain!

Simple to moderate, easy to understand, with various types of puzzles, it's impossible not to enjoy this book.

You can take it with you, and work your brain anywhere.
One a day, it's a simple way to get motivated. And, after 90 days, you'll want more.

These logic puzzles are fun and there is a good variety. The easy ones are good to start off warming up the brain and the more difficult ones definitely pose a challenge. I love logic puzzles and even I had some trouble with some of them. I also appreciated the variety of puzzles, with some I hadn't even encountered before.

I really really appreciate the larger font used here. I'm forever enlarging the text on ebooks and I was so happy to be able to see everything clearly even without that. Also the larger boxes for filling in answers.

I have been really enjoying working through these puzzles and will continue to do so.

*Thanks to Zeitgeist for providing an early copy for review.

A wonderful collection of puzzles of increasing difficulty, great for brain training or just for fun! The puzzles are all well-explained and well-made.

I enjoy logic puzzles and liked the idea of one per day. The puzzles given were achievable without requiring a significant amount of time out of your day. I began these during a business trip and enjoyed engaging my mind on these, despite having full days. It was like a little stress reliever. I would say my idea format for this would be a paper book, as it may be difficult to solve on an electronic format for some.. Overall this could be a great book for anyone that enjoys puzzles.
