Evil Killer Sudoku puzzles are the ultimate challenge for Sudoku lovers. With no pre-filled cells to base one’s deductions on, the players are forced to use their reasoning skills from the first moment they encounter the grid.
They are mostly suitable for expert players because there are no obvious solutions to any of the cells. The only way to break the grid and start solving its mysteries is by combining advanced Sudoku and Killer Sudoku strategies.
That being said, online evil Killer Sudoku grids are not as unforgiving as those of classic puzzles. They are hard to crack in the beginning, but as soon as a few cells are solved, their difficulty level greatly recedes because cross-referencing the cages provides more information than that in a simple Sudoku grid.
