I see the difficulty level has been maintained (or possibly even increased?) for yesterday's difficult killer sudoku. I was travelling yesterday and eventually got it completed with less than 5 minutes to spare. It's only been solved 96 times so far - I presume this is close to a record low (in percentage terms) for a killer sudoku?
Yes, I kept the high level for the Friday Killer Sudoku (and upped the rating to 6 stars),
but re-ran the Saturday ones (down to a more acceptable level
)
You're probably right about the record too, will check this.
