The Times Ultimate Killer Su Doku Book 11: 200 of the Deadliest Su Doku Puzzles

These diabolically difficult Ultimate Killer Su Doku puzzles will really put your brainpower to the test as you warm up with the 150 Deadly Killer puzzles before steeling yourself to take on the 50 Extra Deadly Su Dokus. The puzzles use the same 9x9 grid as a regular Su Doku, but have an extra mathematical element that multiplies the challenge. The aim is not only to complete every row, column and cube so that it contains the digits 1 to 9, but also to make sure that the outlined sections, called cages, add up to the number given in each cage.
