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.

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.
