99 Impossible Sudokus

SUDOKU LIKE YOU'VE NEVER EXPERIENCED
Because there's a catch. Mixed in with these 99 impossible-to-solve brainbusters is one solvable puzzle. Your goal is, therefore, not to solve but to deduce what cannot be solved. Will you try them all or determine how to deduce solvability at a glance?
ONE PUZZLE IN THE FORM OF A BOOK
Are you tired of the simple challenges that sudoku magazines can offer you? When presented with an ordinary sudoku, you know the exact strategies that take you to the solution. Well, not here. In this book, your goal is not to solve but to deduce what cannot be solved. Sudokus turned upside down offers a fresh challenge for the bored puzzleheads.
For non-puzzlers, this book offers something, too! Give these puzzles to your egghead friends and watch them struggle. That insufferable nephew? A puzzle. That colleague who thinks they're better than everyone else? A puzzle. Your know-it-all aunt? A puzzle. Who's the intellectual in the family now?
It falls to you or the masochistic puzzle-head to whom you gift this book to distinguish the nonsense from the logical.
This book contains 99 impossible-to-solve sudokus and one solvable. Maybe it's the next one? Or a funny number? Or the last one? Better get cracking to find out!
