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.

• Mondays and Tuesdays the focus will be on single-digit techniques. Expect finned fish, coloring and fancy patterns.
• Wednesdays and Thursdays uniqueness-based techniques are also possible.
• Fridays and Saturdays you may encounter several ALS, XY-Chain and 3D Medusa techniques.
• Sundays you will encounter the worst Nightmares. Anything goes.
