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.
