Daily Sudoku Nightmare

SudoCue offers you a Daily Nightmare Sudoku puzzle. This number 797, the entry for Sunday, February 17, 2008.

The difficulty will depend on the day of the week.
- 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.
