Re: today's difficult Killer Sudoku has more than one soluti

Part of the reason I struggled earlier is that I saw that the pairs at a5-b5 and a9-b9 appeared to be 6 and 8, signaling a non-unique solution. So I tried to find a different way around it without success. The values at c1, f1, and i8 don't help to resolve the deadlock at a-b5 and ab-9.
I just gave a few values in the "cycles" that I saw.
The last two rows:
495317862
867249531
In any case, I sent the database solution to anyone who submitted a solution
(I get a warning message here when a supposedly incorrect solution is
submitted for a puzzle).
Now I've got about an hour to fix the problem, or I'll probably have to
remove tomorrow's Killer Sudokus just in case.. :(
