The latest volume in the hugely popular Killer Su Doku series from The Times, featuring the highest-quality puzzles with an extra element of arithmetic. Although both number puzzles share a lot of similarities, there’s also a major difference – amount of arithmetics involved.The first is to learn the combinations of numbers that have the least options: there are tables available on the internet that contain the various different ways that certain numbers can sum together and these are very useful. For instance, if you have to make 17 from two squares in a killer sudoku, then you know straight away these contain the 9 and the 8 so they can be written in as pencilmarks and removed as options from all the other squares in the grid. The Times Ultimate Killer Su Doku is not for the fainthearted. The puzzles use the same 9x9 grid as Su Doku, and have an added mathematical challenge. The aim is not only to complete every row, column and cube so that it contains the digits 1-9, it is also necessary to ensure that the outlined cubes add up to the same number as well.
