The Largest Sudoku Book in the History of the Universe: 2000 Puzzles with 5 Difficulty Levels

Not just "The Largest"; this has become now my "My Favorite" Sudoku book in the history of the universe. The book is well-made - binding is sturdy, puzzles are easy to read, and pages are easy to write on and thick enough that puzzles don't bleed through to the other side. And the puzzles are nicely graded in 5 degrees of difficulty: "Easy" puzzles are just that, "Medium" puzzles are slightly harder, "Hard" puzzles are challenging but still quite doable. "Grueling" puzzles are, well, grueling (I can solve about half of them), and "Diabolical" puzzles are beyond me (so far - but I'm not giving up!). There are 400 puzzles of each type. In other words, this collection is large enough, and the range in difficulty is wide enough that there's lots for Sudoku lovers of any skill level to enjoy and grow on. Kudos and thanks to Kiyo Tanaka for this wonderful collection!Just one (very nitpicky) comment: In my edition (2014), the solutions given on page 424 for puzzles 1533 - 1536 are incorrect. There appears to be a printer's error, as these are actually just repeats of the solutions for puzzles 1525 - 1528, two rows above.

Hard to hold.

I'm out of work all week with a pulled ligament in my right knee, couldn't even bend my right leg the first week and this is my second week of recovery. This book has helped my brain from rotting with all the junk on TV now. Seriously a lot of these shows are appalling and I can't believe they are on public television! So between this book, reading books, and some history lessons from Assassins Creed I may survive the week. Plus I absolutely love that it has diabolical as a level of difficulty! Now I feel like an evil genius every time I solve one!

well I'll be dipped. Here I thought I was a decent sudoku puzzler and this book, while it is indeed a very large collection,it's difficult and almost frustrating. Out of the first 15 EASY level puzzles, I could only complete ONE successfully. My usual strategies do not work, such as process of elimination and logic. Trial and error is no fun. Not for the sudoku beginner.UPDATE... found a way to salvage these puzzles. Just fill in a couple more numbers using the answer key in ink. They become more do-able and relaxing. Fill in about 5 more spots in ink in each puzzle, several pages in advance, otherwise I couldn't do them.

There are SO MANY sudokus in this book. Great at keeping your mind occupied during long flights or car rides!

Great value for the money. This review is based on my experience with the "EASY" puzzles. The "easy" puzzles, however aren't all that "easy". I don't expect there to be no challenge, but I shouldn't have to bust my brains, either. However, I do the puzzles for pleasure and mental exercise and to fill in my idle moments, not to spend inordinate amount of time on it, nor to be frustrated, nor needing to track the possibilities for every square to attempt to figure it out without checking against the solution puzzle. I have only worked the lowest "easy" level so far and even with filling in the possible numbers in many of the squares as I have worked the puzzle, I've had to get a hint(s) from the solution puzzle many times to finish working it through (3-6 hints usually get me over the hump). Not sure how the more difficult puzzles will compare, but it's not looking good. I consider myself a proficient solver of Sudoku (up to the medium level--need hints on the hard ones) and do not recommend these puzzles for those who find Sudoku challenging. However, if the mental drain isn't too tiring and you're up to a challenge, it'd be a great purchase.

I buy Sudoko books for my husband every Christmas as one of his gifts then more sudoko books during the year. When I saw this giant book that offers over 2,000 puzzles I was ecstatic. He loves it!! My only disappointment is that it doesn’t have 2,000 puzzles but far less.

I enjoy the size, easy to see, many different skill levels. We take long car rides this is a great book for that! Great to leave in the car. Great for the cabin just to pick up and do. Great quiet time activity.

Excellent!

Great and challenging

My husband really enjoys it!!!!
