I’ve been recording a solve path for some of the harder “easy” difficulty puzzles at Daily Killer Sudoku. 729, a standard killer sudoku, is the Difficulty 1 puzzle with the second longest average solve time. Check out my full solve video here:
I think it should be a difficulty 3 or 4. Why do you think this difficulty 1 puzzle has a 34 minute average solve time? Try it yourself and let us know!
This is level 5 Daily Killer Sudoku from today with an average solve time of 15 minutes. After 23 minutes it looks like this. What I am missing?
Can anyone help me figure out how to proceed??
