Sudoku Woes

 I have been getting so much better at Sudoku these days that I am able to complete even the ones under "Evil" or "Very Difficult" on most online sudoku websites. Yes, I am quite thrilled with myself :)

So, thought it might be time to go back to this one and see if I could figure it out at last. 

Check out the time stamp on the top left: After 2 days and 21 hours, and on my 4th re-try (earlier 3 attempts have not been included in that time stamp), I totally mucked it up... see the 4th row, 3rd column... the only number it can take is 1, but there is already a 1 right next to it.

😭

5th attempt coming up....
