Welcome to this superb new selection of 100 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 - 9 exactly once in each row, column and 3x3 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.

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!
