Killer Sudoku 2

Featuring 100 more top-quality Killer Sudoku from best-selling puzzle author Dr Gareth Moore, this book is packed with another set of challenging puzzles. Although the book includes difficulty levels that range from easy to hard, easy doesn't mean trivial and hard doesn't mean guessing is needed! Every puzzle in this book will make you think, but they're also always fair. To solve Killer Sudoku, just place 1 to 9 once each into every row, column and box while obeying the dashed-line cage totals. Full instructions and number-table aids are given at the front of the book.
