Confident solvers who think they've got Sudoku down cold will have to think again, because these are absolutely the most fiendishly difficult, devilishly baffling Sudokus ever devised...and the biggest, too.  Created by hand in Japan--from Nikoli, the company responsible for the puzzles' popularity in that country--the collection includes megasudokus on a 25 x 25 grid, designed to give even the sharpest minds a workout. True to its title, it's the ultimate challenge, and one that millions of Sudoku-obsessed fans will find irresistible. And for total newcomers brave enough to high-dive in at the deep end, there's a quick tutorial to get them started.

Awesome Megasudokus

User Review  - pmichel -

This is an excellent Sudoku book. But beware that once you start doing the Megasudokus its hard to go back to the regular 9grid type! Also the Megasudokus are really small on the page so I recommend blowing them up on your scannercopier. Read full review
