    In the 'killer' variation of Su Doku there is an element of arithmetic involved and few, if any, number clues. The challenge is to complete the grid as normal but make sure that the numbers within a second, dotted line grid add up to a specific total. There are 110 puzzles, arranged by difficulty from Gentle to Deadly, with answers at the back.
