Sudoku & number puzzles

Traditionally, Sudoku is a logical number arrangement puzzle. In Killer Sudoku (Book - 2) the objective is to fill a 9 x 9 grid with single digit numbers, so that each column, row, and sub-grid of the 9 X 9 grid contains the numbers 1 to 9. Killer Sudoku is a variant that adds an arithmetic dimension to this logic puzzle. Not only should the number arrangement be in accordance with the traditional Sudoku rules, the numbers in outlined cubes must add up to a specified sum. Killer Sudoku is thus a combination of logic and a math puzzle. This particular type of Sudoku was already an established variant on the traditional Sudoku in Japan in the 1990s. It was introduced to the world by the British daily, The Times, in 2005. This book, Killer Sudoku (Book - 2), contains a varied collection of Killer Sudoku puzzles. It has some simple and moderate puzzles as a warm up exercise. But, this book focuses mainly on the tough, tricky, and deadly levels. It challenges the logical and arithmetic skills, and can become quite addictive.
