Published to coincide with the launch of 'Killer Su Doku' in the The Times this September, this takes Su Doku to the next level.
The puzzles use the same 9x9 grid but there is a double 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. Killer Su Doku is enormously popular in Japan and the craze will no doubt catch on in the UK.
