Grosse Sudoku Puzzles : Difficult to Nightmare - Book 1 (Large type / large print ed)

Latin Square puzzles like Sudoku have been around for quite a while but even though most have numbers and 3x3 squares, that rarely applies in this book.

Some have extra domains and some have different shapes.

Nine-letter words and random letters are often substituted for numbers.

All good fun in a nightmarish sort of way. The levels in this are 'Difficult to Nightmare' and whilst you might find that you just 'click' with some of them, remember that you have been warned - they all work out with just logic so you should be able to do them.

This book has 200 puzzles with only one puzzle per page.

This is the standard-sized book but you might need the extra space in the large print version.
