Daily Sudoku Nightmare
SudoCue offers you a Daily Nightmare Sudoku puzzle.
The difficulty will not be too excruciating at the beginning of the week but will increase as the week proceeds.
If you prefer easier Sudokus, check out the lite page with 4 grades of daily puzzles. For those who like something inbetween, try the One-Trick Pony, which only requires a single advanced solving step.
You can print this page or select the number string below the grid and paste it into a solver program that accepts this input.
