The newest volume in the Killer Su Doku series, featuring the highest-quality puzzles with an extra element of arithmetic
This 11th addition to the successful Times Killer Su Doku series will test puzzlers' skills to the limit, adding the challenge of arithmetic and taking Su Doku to a new and even deadlier level of difficulty. The puzzles use the same 9x9 grid as Su Doku but with an added mathematical challenge. The aim is not only to complete every row, column, and cube so that it contains the digits 1 thru 9, it is also necessary to ensure that the outlined cubes add up to the same number as well. With 150 new Moderate, Tough, and Deadly Killer Su Doku puzzles, there is no chance to ease in with Easy puzzles. For those who like to live dangerously and push beyond their mental comfort zone, steel yourself for the Times' next, terribly tough installment.
