Perhaps we need to collect all these unsolvables together, as we have a much smaller sample set of Killers to work with than vanilla Sudokus.


Hi all

On Glyn's suggestion, i browsed the forum for all puzzles (at that point) considered unsolvable.

Here is the first list of unsolvables(from this forum).

1) Sept 28th 2006: SudokuEd's UTA 1

Solved: Walk-through at http://www.sudocue.net/forum/viewtopic.php?p=3259#3259

PS:

3x3:d:k:6913:6913:5122:5122:5122:5134:5134:5134:5134:5138:6913:6913:6913:5122:1792:1792:2320:2320:5138:4373:4373:4373:5654:5654:5654:1305:1305:5138:4373:4390:4390:6439:5941:5941:5941:5941:5915:4390:4390:6439:6439:6439:3882:5931:5941:5915:5915:5915:5915:6439:3882:3882:5931:3911:3894:3894:2362:2362:4355:4355:5931:5931:3911:1343:1343:2370:2370:5966:4355:4355:4432:3911:5704:5704:5704:5704:5966:5966:5966:4432:4432:



This puzzle only has a walk-through from Richards solver. I think it also needs a human effort.

2) Dec 29th 2006: SudokuEd's Bullseye 3(aka Assassin 30V2.1)

Solved: Walk-through at http://www.sudocue.net/forum/viewtopic.php?p=4203#4203

No Tag effort reported on this one.

There hasn't been any mention of anyone solving or trying to solve this one.

I think after the struggle of A39V2 people were kind of tired of the cage pattern.

5) April 28th 2007: Para's Assassin 44V1.5

Solved: Walk-through at: http://www.sudocue.net/forum/viewtopic.php?p=3971#3971

This one might be a bit out of place, but as it was judged difficult and no WT at all, i am going to put it in. This probably be the first to be solved out of this set.

6) May 11th 2007: Ruud's Assassin 50V2

PS:

3x3::k:3072:3072:4098:4098:5636:2565:2565:3335:3335:3072:4618:4618:5636:5636:5636:5647:5647:3335:2834:4618:4618:2837:11542:4119:5647:5647:2330:2834:5916:2837:2837:11542:4119:4119:5154:2330:5916:5916:11542:11542:11542:11542:11542:5154:5154:2605:5916:2863:2863:11542:4658:4658:5154:2357:2605:3639:3639:2863:11542:4658:6204:6204:2357:4159:3639:3639:5698:5698:5698:6204:6204:4167:4159:4159:3146:3146:5698:1357:1357:4167:4167:



There was a tryfurcated opening for this puzzle by Glyn. But i guess there must be a nicer way through it... some day.

7) July 20th 2007: Ruud's Assassin 60RP

Solved: Walk-through at http://www.sudocue.net/forum/viewtopic.php?p=4324#4324

There has been made a start to this puzzle, except this hasn't led to much yet.

8) July 27th 2007: Para's Special Killer-X 4V2

PS:

3x3:d:k:2560:3585:3842:3842:5124:3589:3589:4615:2568:3593:2560:3585:3842:5124:3589:4615:2568:5137:3602:3593:11540:3585:5124:4615:11540:5137:3866:3602:3602:3593:11540:5124:11540:5137:3866:3866:5156:5156:5156:5156:11540:5161:5161:5161:5161:5165:5165:3887:11540:5169:11540:3379:4404:4404:5165:3887:11540:2873:5169:3643:11540:3379:4404:3887:2624:2873:3906:5169:2884:3643:2630:3379:2624:2873:3906:3906:5169:2884:2884:3643:2630:



Horrible result of an atempt to create a suitable Killer-X 4V2.

9) Aug 1st 2007: Mhparker's Assassin61XV3

PS: 3x3:d:k:4096:4096:4354:4354:2820:5125:5125:5127:5127:4096:5130:4354:4354:2820:5125:5125:3088:5127:6674:5130:5130:4629:2820:4631:3088:3088:4378:6674:6674:4629:4629:4631:4631:4631:4378:4378:4644:6674:6674:3111:3111:3111:7722:7722:4378:4644:4644:5423:5423:5423:3378:3378:7722:7722:4644:3383:2872:5423:3642:3378:2620:3901:7722:2623:3383:2872:4162:3642:4164:2620:3901:2887:2623:3383:4162:4162:3642:4164:4164:3901:2887:



Another horrible creation while trying to make a suitable V2 for an assassin.

A62V2 might need to be added to this list. But as no real attempt at that one has been made, so i'll keep it off. But i think a list of 9 puzzles suits Sudoku.

So the challenge is up to remove these puzzles from the list.

greetings

Para

Good stuff collecting them together!

I'm sure it's well known on this forum that I believe that all Assassins, except for a few easier early ones, and all forum puzzles ought to have at least one posted walkthrough if they can be solved manually. Your message should encourage that to happen!

I have solved CDKV3 with a couple of hints from Ed. I was planning to post my walkthrough after doing the ones for SampuZ4V1 and SampuZ5 but it got delayed because of our recent move. You have reminded me that I must do it soon.

I started your A44V1.5 but didn't get very far. I can post my starting moves if anyone is interested and would like to pick it up, either as a tag or just to finish it off.

I also started your Special Killer-X 4V2 and got further than with A44V1.5 before I got stuck. Again I can post my starting moves ...

I assume that the walkthroughs should be posted to the threads for those puzzles. Do you also want a short message posting in this thread to say that there is now a walkthrough? Alternatively should we inform you by PM so that the solved puzzle can be removed from your message?

Hi

I think when we got a walk-through i'll just put a similar message under each puzzle like Mike Mepham did, that there is a solution path.

Yes it is probably more suitable that each puzzle gets it's walk-through posted in their original thread. Except maybe number 8 and 9 because they were posted in a thread to show a point and there is already a Tag going on. So they might need a seperate thread otherwise their will be different Tag solutions running through eachother. And that would be very confusing.

greetings

Great idea Para (and Glyn). Brings back lots of memories looking through that list.

I realize I missed Mike's Assassin 61X V3 from the ratings page so will add that in. Sorry Mike.

Can add one more to the list. This one didn't have a pic - but should be a real good solvable puzzle. Better to call it not-yet-solved.

I've done a step count for each of the 10 unsolvable puzzles if anyone is interested. I hope that using step counts will help us to design puzzles at the desired level. In tt.

Here's another one for the record books. Got lost after my initial post, it was mentioned there.
It's kinda funny that some monsters avoid this thread by us being so stubborn in wanting to solve the really brutal ones. Like A48-Hevvie and the Brick Wall.
