The Colossal Book of Large Print Sudoku: Medium to Hard Level, 500 Puzzles Paperback – Large Print, July 8, 2015

I bought this book for my wife, who an avid sudoku player. She completes about 15-20 puzzles per day and it by no means the best player in the world, but usually, she is in the top 5% of people she plays with. The last cruise we went on had daily competitions and she won them every day playing against 15-30 other people. I only say this so people understand the context of my review.My wife loved this book because it was big and easy to make small notes on, but she said that it is not at all a medium level set of puzzles. She would rate this book as hard to very hard and has to refer to the back of the book occasionally to finish the puzzles, so if you are truly a medium player, don't buy this book as it will greatly frustrate you.If you are an expert sudoku player and can complete hard to extreme puzzles then you will like this book very much.

LARGE PRINT. One puzzle per page. Lots of blank spaces even in boarders to write notes. Book is over an inch thick, which is not a problem. Well worth the money!

This newest Sudoku book just arrived. The paper, type size is excellent. Highly recommend this book.

Good medium and (quite) hard puzzles and very large print (with lots of room for notes). Only downside is that, in part because the answer keys are also large print (4/page), the book is very fat and heavy. I have to use a book holder and it just barely balances on the thing.

My mom loves this book. She is a medium/hard soduko level. She enjoys the size/puzzle challenges and amount of soduko puzzles avail.

Exactly what I was looking for! I wanted puzzles that were challenging and these are perfect!

I bought these for my 93 year old Papa who had a stroke that affected his eyesight and he found these easy to read! The book itself was kind of heavy for him to carry around so he tears out one page at a time to use.:)

Great mind workout book. Very easy to read
