Brain Games - Sudoku #1 Spiral-bound – Illustrated, February 1, 2010

The spiral binding makes it easy to use.

Love these books.

Large print is great. I keep buying the same books over and over when the puzzles become too difficult. :)I also like the spiral bound as opposed to a sewn bound book. Easier to do the page on the left.

I like the books, but they were significantly damage in shipping.

I bought this for my grandson since he loves mathematics. Since students are not allowed to use there phones at school, this is a good way to keep him engaged during down times.

The only ding I give it is that it is a big large. Kind of difficult for sudoku in the go but it is a great collection!

I hadn't done any Sudoku in years. With all the political unrest lately, I needed to take a break! I ordered this and am very pleased to be able to take a break and re-energize my brain. This format - large pages and spiral bound - is perfect for old eyes and not so nimble fingers. I am still only on Level 1, but all of the puzzles have been great so far. Not real easy and not too hard.

I play a lot of Sudoku and with the spiral bound book, I can easily play my game without fussing with the pages. I'm going to seek these kinds of books out for my puzzles!!
