Sudoku Advanced Hints
Sudoku fans: Any advice after the puzzle skill level reaches 4 and 5?
The puzzle seems easier in our Local work Monday through Wednesday, and sometimes on weekends. Which I can manage. However, rarely have I been able to solve the puzzles, Thursday or Friday. (Level 4 or 5) Does the Sudoku experts out there have advice once the puzzle hit these more advanced?
