Weekend Special – Insane Killer
Ok thanks for all your comments to my post regarding the difficulty of some puzzles. I completely changed the rating system and created a large number of puzzles just to test it. As promised – I just posted an extra killer puzzle, rated (by the new rating system) as INSANE. It’s actually one of the puzzles with the highest overall difficulty rating – I hope you find this one challenging. If not – well, I’ll have to redo the rating again :).
Let me know how you feel about this one…
Have a good weekend!

The weekend Killer took hubby 45 mins to do – now he is bored.
Cannot get enough of these to keep him going/amused.
I really enjoyed this one. Found it hard to get started and then a really nice flow as the possibilities narrowed. Took me over an hour. Time well (mis)spent:). Many thanks and keep up the good work.
More, more, more ……..
About one hour to “get rid” of the insane….
I really enjoy Insane more than other difficulty levels…
Thank you again for your beautiful work!

robert,
The insane killer on Sunday is available in the Daily Killer Sudoku column:
Afterward it will be moved to the “puzzle archive”:

I found this one quite challenging, and deserve the rating of “insane”. I even applied xwing in some stage, although it might not be really necessary. I guess what made me feel uneasy was the need to add up a large group of cells. Pardon me but I just prefer to perform mind computation instead of using a calculator (a real one). In this puzzle there are outies of whole bands and stacks and while I was capable of those it just took more time and strained my brain a little bit. Next time I won’t hesitate to open the Excel sheet and let the CPU do all those manual chores…
It’s no good – I’m obviously missing something here. Please can someone give me a little extra clue, I’ve only got 5 numbers so far: r3c7=2, r4c9=4, r5c9=2, r7c7=1, c7c8=2. Lots of candidates in the right hand stack (box 6 with naked pairs and a triplet) and a number of split cages but they don’t seem to help.
Thanks.
