Ok, a few regular readers have requested an INSANE Killer Sudoku puzzle so I had to respond.
This puzzle should be very difficult to solve. In fact, it might require some trial&error attempts to be solved. Do not attempt to solve this puzzle unless you are willing to accept that!
Sorry to disappoint you — the Insane (2308329) was pretty straightforward (but still enjoyable, as always). Don’t know where the trial-and-error would come in.
Insanes are always appreciated!
Always enjoy an INSANE (2308329).I did not seem to need the trial-and-error technique. Thanks for a terrific website.
Insane (2308329): I agree with the comments by Diana and Erica but have to admit it took me three tries because I made the same error in logic the first two times. Thanks for the wonderful series of killer sudoku puzzles.
No trial and error here, either.
It was a very nice surprise for me to be able to figure this one out without having to guess (although I did check my solution as I went). Great confidence booster! 🙂
