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

Nice big book of Sudoku. Puzzles are about 3 by 3 inches, large print. Solutions are actually in the back of the book, it has a spiral binding so it stays open while you use it. Puzzles range from easy to tough. 10 pages of Samurai puzzles in back. Praise Jesus, this is a very nice book, good price. :)

This is my 3rd book. I keep doing this book over and over because it's my favorite. It's easy to see the numbers since the pages are white. It's easy to hold because it has the spiral binding, so no problems with folding the book in half. Puzzles go from warmups to easy through difficult, with an extra section of Samurai Puzzles which are five puzzles in one and fun to do. There are 534 puzzles, so the book is worth the price. By the way, I don't remember any of the puzzles, so it's always a new book for me.

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.

I love these books! I love that it is spiral and I can easily turn to a new page. I've done several of these books over the years, they were a great distraction while sitting with my terminally ill mother in law.

I absolutely love that it has the spiral, it makes it so much nicer when trying to do BOTH sides of the page's puzzles. With a regular book the left side is always a pain. The print is a little smaller than I expected and I do wish it was bigger, which is why I took off a star, but overall it's really nice and it's a good size and it has lots of puzzles so I'm quite happy with it!

I like spiral bound SUDUKO - it is easier to hold and work the puzzles - The print is sort of small if you have issues with small print. This is a great buy to me - it will keep my mind busy for a few months at least.

Have patience and all will work out! Great print size. Well worth the money. I did these years ago and loved doing them and I sure that once you get the hang of it, you will too!Vickie

I think this book is a lot of fun and has many puzzles. Warm-up, Challenging, and Tough are the headings. However, I have had many Sudoku books and to me they should be listed as very easy, easy, and Moderate. The tough puzzles will be great for beginners of people who don't want really hard or difficult challenges, however, they will be too easy for the dedicated Sudoku lover. I enjoy them as a relaxing, fun time, but they are not as challenging as some of my other books.
