Big Book of Sudoku: Over 500 Puzzles & Solutions, Easy to Hard Puzzles for Adults (Brain Busters)

If you are looking for a way to disconnect from electronics and give your "little gray cells" a workout, this is the book to get. I love that it is Spiral Binding (Game Changer): The best feature! The spiral-bound format means I can lay the book perfectly flat or fold it over behind itself. This makes it incredibly easy to use on a couch, in bed, or while traveling without the book trying to close on me. Tear-Out Pages: Being able to tear out the pages is perfect. I can just take one puzzle with me, or work on it without the bulk of the whole book. Plus, I don't have to scan through the book trying to find an unused page True Medium-to-Hard Difficulty: I appreciate that this isn't just filler. The puzzles provide a genuine challenge, ranging from medium to very hard. Screen-Free Relaxation: This book is my go-to for stepping away from screens. It’s a wonderful, relaxing way to wind down in the evening or take a mental break during the day. 500+ Puzzles: Plenty of content to keep you busy for months. Solutions Included: Located at the back for when you get stuck! I highly recommend this book for seasoned solvers looking for a convenient, high-quality, and challenging Sudoku book. It makes for a fantastic, relaxing, and mentally stimulating hobby. Bonus for me is the binding: Spiral-bound (lays flat).

Love sudoku puzzles. The spiral is very nice. I will be ordering again.

These puzzles range from simple ones to tough ones, and I like having that variety - the easy ones for when I want a quick break from doing something different and the harder ones for when I have time to work a bit longer. There are some "Samurai Sudoku" puzzles, too - 4 9X9 grids with a 5th grid intersecting part of each of the others. I'd never done those before, and I like them. The binding is quite good. I usually tear out the pages as I am done with them, and the binding holds up well for that. The paper is good for writing with both ink and pencil, and it is sturdy enough to stand up to erasing. When I first got this book, I thought that perhaps the puzzles, two to a page except for the Samurai ones, might be too small. I admit to sometimes jotting numbers in the bottoms of the squares when I am stumped. I can still do that with this book, despite my initial reservations. I use those little Post-It arrows to mark the first empty page of each section so it's easy to find the degree of challenge I want at the time. Little built-in tabs would have been nice but that would probably have made this not such an easily affordable book. I don't know if this book comes in different volumes, but if it does, I'm going to get another one when I get close to running out of these puzzles. For me, doing these puzzles is very relaxing.

Fun puzzles, and the spiral binding makes it easy to lay the book flat.

Enjoying (well kinda) this book - it's exactly as advertised, and I am happy with the quality and the price. I am struggling abit to do the puzzles, but I think that is more on me than it is on the book producer. I will continue to use this product to sharpen my thinking and wouldn't hesitate to order from this company again.

Great book with appropriate skill levels; from easy to difficult.

Good variety of puzzles with a lot in the medium to hard range. (Medium to hard for me - I do not like to guess to proceed.)

Great great

Fue un regalo para mi Papá que le encanta resolver sudokus, tiene 2 semanas y ya va x el 50. Del modelo en el que vienen 5 sudokus en uno no trae muchos en el libro, pero con los demás es suficiente, además incluye las respuestas de cada uno al final. Definitivamente una excelente compra

It was as is. Good quality and addictive indeed.

Love it, lots of sudokus. Love that it's easy at the beginning and gets harder l, great for people who wants to start with the instructions at the beginning!

Bought this for my father who is always enjoying doing the sudoku in the newspaper. The puzzles are well spaced out, good size and printed clearly. The pages are pretty thick and good that they can be torn out if wanted. The Sudoku are arranged by difficulty from easy to hard and this is a pro and a con. It’s probably the sensible way to layout for being able to find them but my dad likes to work through the book but this means he does all the easy and is going to get stuck soon with nothing but the very hard ones. Might have been good if the hard ones had been mixed in a bit because I can see him pulling his hair out soon :) Overall very good for Sudoku lovers though.

Decent price
