Caida: I did some heavy combo crunching in order to break this puzzle - I'm sure there must be a more elegant solution
Afmob: relaxing Killer. After all those 1.25 and 1.5+ Killers it was really fun to tackle an "Assassin" without spending all your brain power on it :lol:

. Rating: 1.0. I didn't mark any key moves but I think using Innie-Outie-Difference you can avoid combo crunching and solve it without any problems
Andrew: The solution really flowed well with my only real work being to put steps in the right order to simplify my solving path. I agree with Afmob's rating of 1.0
gary w: I've actually enjoyed NOT doing an assassin for a couple of weeks. Now I feel a bit fresher and looking forward to future challenges whereas all those 1.25+ brutes were beginning to wear me down!!
mhparker: I was beginning to get concerned that the Assassins were generally becoming too difficult ... In particular, we weren't getting any 1.0-rated puzzles any more.... Indeed, I was even starting to consider producing "Lite" variants instead of V2s at times!

mhparker, lead-in: Est. rating: 1.5
Caida: I can't remember off-hand how the ratings go - but this didn't "feel" too difficult. I think it's about a 1 (maybe 1.25)
Afmob: It'll be interesting to see if other users can solve it without resorting to the one difficult move..Rating: 1.25. This is a one-trick pony and I think this one move Caida and I used is too difficult/advanced for a 1.0 Killer
Andrew: Wow, this was a tough one! It stretched my brain power to the limit...If I had to rate this puzzle, then it's a 1.25 just on the moves but if difficuly in finding the key breakthrough is taken into account then IMHO it's a 1.5

Afmob: I thought this one was a monster since SS rated it 2.02 and JSudoku used XY-Chains and Turbot Fishes to crack it. But I managed to crack it in (with) two moves... there is nothing complicated about this and even those moves are easy to see I think. Rating: 1.25
mhparker: I agree, although probably a high 1.25
Andrew: Although I used the same key moves as the others, I missed one early move....Missing that early step didn't seem to make the solution path any harder so I'll also rate this puzzle 1.25
sudokuEd: Even knowing there was an easy way to solve this one, it took me many hours to find the key. Felt more like the SSscore to me - but then starting again to get straight to the unlocker: how easy

sudokuEd, lead-in: This puzzle has a ridiculously low SS(v3)score of 1.05. But it took about 6 sessions to finally find the 2 key moves...they are not hard moves, just very-hard-for-me to find. So, I give it a rating of 1.25
Afmob: I agree with Ed that this Killer should be rated above 1.0. It took me some time to find step 5a (though the step itself is not difficult) Rating: (Easy) 1.25
gary w: I'ld rate this as 1.25 at least..or maybe I'm out of practice!?
Andrew: Afmob's steps 2d and 3b are the sort of steps that are so easy not to spot..Using an innie pair and an outie pair.. isn't a particularly common step. Steps 4a and 5c were also interesting. With those steps, together with Afmob saying that step 5a was difficult to spot, I felt that it should have been rated 1.25 rather than (Easy) 1.25
mhparker: I took a very similar route to Andrew..Despite avoiding a contradiction move, I would still go along with Andrew's rating of a typical 1.25, rather than an "easy 1.25"

sudokuEd, lead-in: I spent Easter '06 trying to solve this beauty and have been hopelessly hooked on (difficult) killers ever since
Afmob: you could totally ignore some nonets to crack it ....At first I wanted to rate it 1.75 but I discovered that the complex combo analysis I had used wasn't necessary to solve it so I deleted it from my wt. Rating: 1.5. I used one forcing chain and a Hidden Killer quad
mhparker: Afmob's 1.5 rating! :shock:

(<-- very surprised, because I would have expected a 1.75 - or even a 2.0 :!:

- here, due to need for a chain to break the deadlock)
sudokuEd: Afmob, some really great moves in steps 1-3! But your first instinct works much better for me - no way could I seriously put this classic onto the rating sticky as a 1.5 (more like a 2.0 with that type of chain)!
Afmob: I rated ND 9 only "1.5" because when I solved it, it flowed quite well meaning I didn't really came to halt despite those difficult moves. Also my wt is quite short and doesn't have this many ! moves where as my other 1.75 walkthroughs are usually quite large and have many ! moves and they also wouldn't be cracked with one chain only... So maybe it's more a hard 1.5. Compared to UA97 V2 which I'm tackling at the moment (made 4 placements so far) ND9 is way easier
Andrew (in 2012): I'm working on nd's killers again, having intended for a long time to try them all and write walkthroughs for them; I originally solved six of them back in 2006 before I was first introduced to Ruud's Assassins. This is the first time I've tried nd#9.
In Afmob's solving path I loved step 3a; I didn't look at 21(4) cage at R5C8 until much later in my solving path.

Oh Afmob, some really great moves in steps 1-3! But your first instinct works much better for me - no way could I seriously put this classic onto the rating sticky as a 1.5 (more like a 2.0 with that type of chain)! Did the 1.75 way you used still need a looking-3-ways-chain? I'd much, much rather combo-crunching.

If it did still need that chain, here's a way that looks simpler for step 4.

4a) no 7 in r9c4 because of 7's in n1
i. 7 in r12c3 -> 7 in n7 in r9c1 -> no 7 in r9c4
ii. 7 in r2c2 -> r9c34 = 8 (i/o c12) -> no 7 in r9c4
b. r9c1 = 7 (hidden single r9)
c. r6c1 = 9 (hidden single c1)

On it goes from here.

Jean-Christophe, lead-in: rating "much too easy for regular members"..SudokuSolver v3.0 scores: V1: 0.90
Afmob: It can be solved using a (very) basic Killer technique..Rating: 0.75-1.0. I used a Killer pair to crack it. I am not sure about the rating since I've never rated such an easy puzzle
Jean-Christophe: I personally would not qualify "(very) basic" such techniques as killer naked pair or combination conflicts like you used. Also consider the number of In/outies with three cells in this puzzle, most useless at first
Andrew: Using elimination solving, YAK96 was an easy puzzle. I expect it could still be solved fairly easily without using elimination solving. This puzzle only requires one killer pair ..(which can be spotted even without using elimination solving)..and a few simple 45s so I'll rate it at 0.75
gary w: I certainly wouldn't say v1 was "much too easy" for regular assassinators....Took me over an hour so I'ld rate it as harder than virtually all the "deadly" killers that appear in The Times..0.75??

Jean-Christophe: rating "not sure it's hard enough for regular members"..SudokuSolver v3.0 scores: V2: 1.79 JSudoku cannot solve V2..I designed ...(tricky) moves..
Afmob: UA 96 V2 was quite challenging and interesting ..It had a regular X-Wing which you don't find that often in Killers...Compared to ND #9 my moves wheren't much more complicated but it took me some time to find them ... That's why I rate UA 96 V2 higher..Rating: 1.75. I used combo analysis and a forcing chain
Andrew (in 2012): J-C's comments on the tricky moves designed into this puzzle are interesting. I missed both of them, I rarely spot crossovers, but I found the other tricky move innies-outies for C5 (not mentioned by J-C) very helpful. Afmob found a better area for detailed combination analysis, giving a shorter solving path than mine although not necessarily using easier steps. I agree with Afmob's rating of 1.75.

mhparker, lead-in: Est. rating: 1.5..SudokuSolver v3.0 scores this beauty at 1.83, but that's probably making a bit too much of a meal of it!
Afmob: It seems Mike found another Killer where the SS rating is quite off..Rating: (Easy) 1.25. I used a Killer triple to crack it
Andrew: I rate the way I solved this puzzle as Hard 1.25. However if the key move is used, then it becomes Easy 1.25 as rated by Afmob

Afmob: Here is the first Killer I've created and published so far..(Estimated) Rating: SudokuSolver rates this one 0.96 but it can be solved in an easier way
Nasenbaer: It took me a lot longer than I had thought. Somehow I always got sidetracked..with all the the things I might not have needed
sudokuEd: I'd call this one a hard 1.0 rating since it took a long time to find my break-through. Not the type of move I look for very early. But admittedly, not that difficult
Jean-Christophe: I personally did not found it really hard. I would even say it's easy if you're familiar with Kakuro
gary w: I found this one fairly easy.Took me 35 minutes to complete which was OK,long enough for a Saturday evening!!If we rate the Times "deadly" killers as about 0.5 I'ld say this one is about 0.75
Andrew: I also found uA97 hard going (I guess my "killer brain" had partly switched off!) until I realised that hidden cages .. can be used for clashes ... rather than just for clean-up eliminations. Then I restarted and found it a straightforward puzzle. Based on my re-worked solution I'll rate.. uA97 at 1.0
