Nice travel size
4 out of 5 stars
Nice travel size
Compact little spiral book. Smaller than I thought but excellent for travel. Numbers are a bit small so might be hard to see without reading glasses on. There are puzzles on the front and back of each page which was a nice surprise. Nice to see all the paper utilized.

    5.0 out of 5 stars Very challenging and lot's of fun!
    Reviewed in the United States on September 24, 2017

    Very happy with it - the compact size, the quality of the pad itself, the wire-o binding (as opposed to spiral), the fact that it's one puzzle per page, the good-sized print, and of course, the challenge of the puzzles. I've done 18 of them thus far and they are definitely quite challenging. The easiest of them took me roughly half an hour, and some took a few hours. You often reach a point where you have two options rather than one, and thus you have to do some trial an error.

    The way I play it is that I have an actual Sudoku board (the plastic blue one with the white plastic tiles). I set up the red numbers according to the puzzles in this booklet, then I solve it regularly as far as I can, and once I reach a point where I have two ore more options (but no single definite move) I start placing in the numbers sideways. This way, if the option doesn't work then I just undo those sideways numbers and know by default that the second option must work - and it does. You just have to keep track and remember what those two options are as you try out the first one. And this is only the expert levels. I haven't even gotten to the grandmaster and super grandmaster levels yet! I do the puzzles in their set order and when I complete one I make a mark on that page. This way I know which one's I've done already. I plan to go all the way through the book, then do it over again, marking each page a second time as I complete it a second time. I plan to place the numbers in the board sideways the second time around (e.g. if you take the booklet and turn it 90 degrees and look at the puzzle as if it's set up this way). Then the third time around I'd turn the booklet upside down, the fourth time another 90 degrees, and then back to the regular way - over and over again. Considering how many puzzles there are and their level of difficulty, I don't anticipate that I'll remember the solutions by heart after going through the book over and over, especially considering I'd turn the booklet at 90 degree angles each time.

    5.0 out of 5 stars Great Sudoku in a portable size.
    Reviewed in the United States on March 28, 2016
    Verified Purchase
    I really like doing Sudoku to keep mentally sharp.

    I no longer buy the Sudoku magazines because they are way too easy fot me. I do Sudoku, and play Bridge to stimulate my mind. I will be 61 years old next month, and want to kerp Alzheimer's and dementia at bay.

    I can solve a medium Sudoku in about 7 minutes, and a hard Sudoku in 10-13 minutes

    I really enjoy thr challenge of the extreme, Grand Master, and super grand master levels of difficulty. Some take me 40-50 minutes to solve.

    Most people are doing Sudoku THE WRONG WAY!

    They read books on solving Sudoku and think the only way to solve hard Sudoku is to use the full possibility matrix.

    THE FULL POSSIBILITY MATRIX IS NOT YOUR FRIEND. IN FACT IT CAUSES MORE PROBLEMS THAN IT SOLVES!

    Why do you think strategies like X Wing, XY wing, star fish, squirm, and about 60 other strategies were invented? Becsuse the possibility matrix PUTS SO MUCH GARBAGE ON THE PUZZLE YOU CANT SEPARATE THE USEFUL INFORMATION FROM THE USELESS TRASH!

    I only use three strategies and solve level 6 Sudoku puzzles. I'm not going to argue with success. Try my method. I think you will be surprised.

    1. Cross hatching. This is thd first Sudoku strategy everyone learns.

    2. Streamlined possibility matrix. If you see two places s number can go or a row or column inside onr of the boxes use pencil marks. Other than that dont worry if a number can go in 8 different cells. Its not worth your time. If you can avoid the trap of the possibility matrix you will start seeing pairs and triples that you couldn't see before becsuse there was so much garbage on the page.

    3. Fill It In. Every once in a while stop and look around at the 9 boxes, rows, and columns. When you ser a box, row or column almost solved see what is missing and ser if you can solve this one box, column or row.

    The tiniest little bit of information may be thr keystone that makes the rest of the puzzle fall like s bunch of dominoes.

    My sister was a firm believer in the full possibility matrix even though i kept telling her my way was better. So i challenged her to a race on two copies of a medium puzzle.

    She gave the start command, and i had my copy of the puzzle solved before she had written down the full possibility matrix. Her expression was BUT YOU CANT BE DONE.

    I told her to print two copies of the same medium puzzle and i would do it again. After i beat her the second time she saw my method had some merit.

    Highly recommended 5 stars

    4.0 out of 5 stars Convenient size, challenging, but a few flaws
    Reviewed in the United States on April 29, 2020
    Verified Purchase
    These puzzles have one of three ratings: Expert, Grand Master, and Super Grand Master. This is about right for my level of expertise. I can solve the Expert and Grand Master levels, but struggle with Super Grand Master.

    The individual puzzle blocks are a little smaller than I like. I can barely write the possible numbers in them, but I can if I'm careful. It would help a lot if they were a little bit larger. Also, the starting numbers are a bit light and don't contrast real well, so it's not as easy to see them as it should be.

    Still, this is a nice compact and challenging puzzle book.

    5.0 out of 5 stars The Perfect Sudoku Book!
    Reviewed in the United States on January 11, 2022
    Verified Purchase
    I have now gone through the entire Sudoku series by Xaq Pitkow and Chronicle Books. Other Sudoku puzzles come up way short in comparison! The spiral binding with hard cardboard covers makes for excellent usability, especially for left-handers. The 3.75"x6" size fits in the palm of the hand, the back pocket, the shirt pocket, and is ideal for working a puzzle. Yet it's large enough even for interior notes (although you must keep them small). The semi-slick paper handles numerous erasures--I've made LOTS of errors!) and the print never fades or smudges. Numerals in color contrasting to grid lines make it visually more appealing. And fainter grid lines outside the puzzle box make for a neater exterior note area. All in all, I find this to be a perfect book for solving Sudoku puzzles. And if they create a newer, more difficult version, I will buy it!
