Weekly Assassin Killer Sudoku

Killer Sudoku is an interesting variant of Sudoku that has gained a lot of popularity lately. The combination of the logic of Sudoku with the arithmetic of the sums provides that extra level of difficulty that many advanced Sudoku players were waiting for.

SudoCue.net presents a weekly Killer Sudoku. In the best of our tradition, this killer is a true Assassin. Don't turn your back on it.

Assassin 59 for the week starting Friday July 13, 2007

Last week's Assassin had an Achilles heel, as discovered on the support forum. Bummer. I expect this one to have more sting. Try not to get hurt.

The vague line below is a code string that you can select, copy and paste in SumoCue. Other programs also support this format.
