 IF YOU'RE LOOKING FOR DIFFICULT.... Jan 30, 2006
By Michael H. Lane
"NinaTX"
There are 10 25X25 grid puzzles in this book. The other 190 are the normal 3X3, but they are difficult nonetheless. You will definitely not be disappointed with this book! The only problem is that you have to copy & enlarge the 25X25 puzzles, so you can have enough room to work the puzzle. The paper quality is great! Buy at your own risk! They are frustrating, buy you can't put them down!

 Challenge? Mar 23, 2010
By Sam
These are all easy puzzles - worked the first several then decided it must be like most other Sudoku books following the easy - medium - hard format. So I went to the last puzzle to work backwards, same thing EASY puzzles.
If you want difficult puzzles forget this one.

Megasudokus Aug 22, 2006
By Mark Hopkins
This book is like most sudoku books--filled with the basic 9 X 9 puzzles (190 in all). While somewhat challenging, for an advanced puzzler these are just more of the same. However, what sets this book apart from the rest is the section on megasudokus (25 X 25 grids). The book contains 10 such puzzles, each requiring hours of work. I suggest using a very thin lead pencil and tearing the pages out (including the solution pages). While cramped, there is enough room to complete the puzzles. These 10 puzzles make this book an absolute steal!

Beware addictive 25 x 25 grids! May 03, 2007
By P. Michel
"medleymaker"
I had been doing the regular 9x9 grids for awhile when I bought this book. Seeking more of a challenge, I skipped the regular puzzles & went straight for the mega puzzles. Aside from them being small, I have had no trouble solving them in the actual book using mechanical pencils (and reading glasses). Each one has taken several hours & I've gotten more than my money's worth just from these 10 puzzles alone. I'm almost done with the last 25x25 puzzle & I'm wishing I had made copies of the puzzles before working them in the book so I could go back & do them again sometime because I'm having trouble finding any more 25x25 puzzles. After doing the big puzzles, you won't want to go back to boring 9x9's.

Challenging without requiring guessing Nov 05, 2006
By Paul Carroll
I just finished solving the last of the 190 9x9 puzzles, having purchased the book 8 months ago while stuck out of town with a blown car engine. Each puzzle can be solved strictly through logic. No guesses were needed. I find that I averaged around 20 minutes per puzzle, with a few being simpler and a few stumping me for a while. As such, I've definitely gotten my money's worth on this book and am moving on to 2 others that I bought at the same time (Mensa Sudoku and Second Degree Black Beld Sudoku) - we'll see how those match up. And, like everyone else, I haven't tried the 25x25 grids yet. Maybe after I finish the other 2 books...
