Large 12x12 Killer Sudoku

Large 12x12 Killer Sudoku Welcome to this superb new selection of 100 12z12 killer sudoku puzzles, hand-picked for your solving pleasure. The rules of killer sudoku are very simple, and are outlined below: - Place each number from 1 - 12 exactly once in each row, column and 3x4 bold-lined box that comprise each grid - The grid also contains sets of cells inside dashed lines (called 'cages'). Each of these cages contains a number. This is the sum total of the cells inside the cage. Thus a '4' means that the cells in that cage sum to 4. A number cannot be repeated within a cage. All puzzles have a single solution that can be reached through the application of logical rules alone - although some puzzles are tough! But with the range of difficulties there is something for everyone in this book from the beginner through to the experienced killer sudoku solver alike. All the solutions are included at the back of the book so that you can check your answers, or seek inspiration if you encounter a killer puzzle!
