Killer Sudoku: Medium Level Killer Sudoku Puzzle Books, Killer Soduko Book

Killer Sudoku (also called Sum Sudoku) are a kind of hybrid puzzle that combine the best features of Sudoku and Kakuro (cross-sum) puzzles. Like a regular Sudoku, the rows, columns and 3x3 blocks contain the digits 1 thru 9. In addition, the dotted lines indicate areas, called cages, which also contain a set of non-repeating digits. If you add up the digits in a cage, you get the sum shown in its clue.

Happy puzzling!
