Killer Sudoku: 200 Killer Sudoku Puzzles Book and Solutions (Hardcover)

<p><strong>Killer Sudoku is a mix of Sudoku and Kakuro. Your goal is the same as in regular sudoku: fill every row, column and 3x3 region with the numbers 1-9 once. The difference is how you arrive at those numbers. </strong></p><p><br></p><p>The objective is to fill the grid with numbers from 1 to 9 in a way that the following conditions are met: </p><p><br></p><p>Each row, column, and nonet contains each number exactly once.</p><p>The sum of all numbers in a cage must match the small number printed in its corner.</p><p>No number appears more than once in a cage. (This is the standard rule for killer sudokus, and implies that no cage can include more than 9 cells.)</p><p>Happy puzzling!</p><p><br></p><p><strong>Contains: </strong></p><ul><li>Glossy cover</li><li>6x9 size top quality paper</li><li>200 killer sudoku puzzles</li><li>Solutions at the end of the book</li></ul><p><br></p><p><br></p>
