Post subject: | Archive - Assassins, Revisits & Other Puzzles |
Assassin Home Page and Index We've now reached Assassin 300! Another milestone! Another major milestone with Assassin 400! And it's 15 years since Ruud posted the first Assassin! Ed and I have agreed that there's no need for me to compile and post full archives after the existing ones which were done some years ago. Links are given to the more recent puzzle threads. There is the risk that a few of them might contain spoilers, which had been removed from the earlier archives. For those interested, there's also the TJK Archive in the Other Variants forum. A few more new TJKs have been posted in recent years. There was a problem that some puzzle diagrams, mostly by creators no longer active on this forum, wouldn't open. These have now been fixed, using original diagrams whenever possible. Many thanks to Ed for providing some replacement diagrams. All the puzzles in the archive entries of Archive Parts D to H up to Assassin 217 also have Diagrams with "udosuk style Killer Cages" by Børge. Alternatively the code string can be copied and pasted into a solver. If you find problems opening puzzle diagrams, please contact Ed for Archive parts A to C or Andrew for part D onwards. Here is Ed's introduction to the Archives, originally posted in Archive Part A. The Archive Index is further down this page; it provides direct links to each part of the archive. Archive & Ratings Updates Today, 2nd June 2008, is the 2nd anniversary of Ruud's Assassin Killers . Ruud's involvement has unfortunately come to an abrupt end which also makes it a sad day. But, as a tribute to the Assassin forum's mighty work over the last 2 years ( ), here's an archive of most of the important forum posts from sudocue.net. For the record, I asked Ruud's permission to use his puzzles here, but he has never replied. [edit: the sudocue forums have since collapsed; they have since reappeared but we don't know for how long they will be available. All Ruud's puzzle pics now included on this thread]. If anyone from sudocue.net does not want their puzzles/posts put here, or if you don't like the way they have been presented, just let me know what you'd like and I'll do my best. Totally confused by the ratings we often comment on? This is the original ratings post by Mike (mhparker). About an Assassin rating scale mhparker wrote: 0.5: Typical newspaper "Deadly". Intended to be done using only limited pencilmarks. NOTE: An important discussion about ratings is here.0.75: Easy Assassin, like some of the very early ones, such as A1. Rarely seen now: all recent Assassins would have at least a 1.0 rating on this scale. 1.0: "Average" V1 Assassin (looking back over a longer period of time). Something like A57, perhaps. 1.25: Harder Assassin. Actually, most recent Assassins seem to have become more difficult than they traditionally used to be. So a rating of "1.25" would be considered the norm now. Typical example: A59. 1.5: Hard Assassin, having a significantly longer and/or narrower solution path, and/or requiring more advanced techniques. The A60 was definitely one of these. 1.75: Very hard Assassin, but still not hard enough to require a team effort to solve. Does not require any hypotheticals. The A60RP-Lite could maybe deserve such a rating. 2.0: Traditional "V2" standard, typically requiring a team effort and maybe (but not necessarily) involving limited use of hypotheticals. Example: A55V2. 2.5: Requires a team effort and several short to medium length hypotheticals. The TJK18 and A48-Hevvie would probably fall into this category. 3.0: "Ruudiculous", requiring a team effort and massive hypotheticals to solve, if it can be solved at all. The A50V2 and (possibly) A60RP could be considered examples of this. 4.0: Puzzles with unique solutions, but which can only realistically be solved by computer programs using backtracking (brute force). The other thing we often mention is the SudokuSolver score (SSscore). This is the score given by rcbroughton's (Richard) solver (downloaded from the software forum). This is a software generated prediction of the human difficulty (ratings). It is often fairly accurate. The lower the score, the easier they should (apparently!) be. But remember - these are Assassins we're rating.... [edit: I plan to update this table with improved versions of SudokuSolver] enxio27 wrote: I've uploaded all of the original Assassins and all of the Texas Jigsaw Killers from Ruud's website here. (Thanks, Børge!) You will need to use WinZip to extract all of the necessary files from this .ZIP file after you download it. The Assassins are in .PHP (browser) format and, when loaded into your browser, will display the puzzle (almost) the same way as it appears on the Web site. Make sure the menu.js, sudocue.js, and sudocue2.css files are in the same subdirectory (folder) as the .PHP files Archive & Ratings Update 2011 by Andrew The Killer Archive is split into sections, the first part containing the first 50 Assassins, plus variants and other puzzles, from Ruud's site; the next two each containing 25 Assassins, etc. from Ruud's site. After that there are sections for puzzles posted on this forum. Because it's harder to find where non-Assassin puzzles are in the archives, the lists of these puzzles provide direct links to each puzzle entry in the archives; if you want to find out the ratings for these puzzles there are rating tables at the top of each archive page. Archive Part A. Assassins 1-50, variants and the following puzzles A New One (aka nd#10) Black-Hole X remote killer Center Dot Killer! (aka CDK) CDK V2 CDK V3 Chevron zero Killer Last Killer of 2006 Name that Album X (unfortunately the album image is no longer included in the puzzle diagram) NonCon Killer PANIV X Para's Killer-X Sampu Z4 and Sampu Z4 V2 Sampu Z5 Special Killer-X (SKX) 1 SKX2 SKX3 SKX4 Uluru-X UTA and UTA2 Archive Part B. Assassins 51-75, variants and the following puzzles Concentric Squares Killer Maverick 1 Transformers X and Transformers X Lite Vortex Killer and Vortex Lite and the "Unsolvables Thread" posted by Para on Ruud's site Archive Part C. Assassins 76-100, variants and the following puzzles Bored89-Easy Bored89-Hard Diagonal Surprise Maverick 2 Maverick 3 Maverick 4 nd's #9 (aka Night of the Living Sudoku) Radial Killer Yet Another Killer (YAK) 94 There are also post-Ruud unofficial Assassins 93-100 on pages 4 and 5 of Archive PART C Archives B and C also include some discussions from Ruud's site. In the past few years I've been working on puzzles which I failed to solve when they were originally posted and ones which I've never tried before. Some of these were puzzles originally posted on Ruud's site and now included in Ed's archive parts A,B and C. If anyone else solves these puzzles and would like them included in the archive, please submit them to Ed; you will be given credit in the list of added walkthroughs. If you solve older puzzles on this site and have a walkthrough, it should be posted in the appropriate puzzle thread and I'll then add it to the archive entry.

Assassins 426-450 Assassin 445 Almost PS Messy One #8 Note that there are also Rainbow Killers in the Other Variants Forum, these use the numbers 0-9 instead of 1-9 Ed took a break from creating new Assassins for much of 2021. Instead he started posting revisits, selecting puzzles from Ruud's Assassin site, which mostly have SS scores of between 1.5 and 2.0 and human ratings at least Easy 1.5. Each revisit post contains a link to the archive thread for the original puzzle. Any further revisits will be included here Archive Part R. Revisits to earlier Assassins and Other Puzzles Includes new variant Assassin 64 V3 Archive Part S. Assassins 451-456 If we can manage to keep going at the current rate of two Assassins per month, we'll reach the end of Archive Part T with Assassin 500 in February 2026; that will be a major landmark! I'll do my best to continue solving and posting walkthroughs for all of them. Also note that June 2026 will be the 20th Anniversary of Ruud's first Assassin! Andrew Credits Ed A very big thankyou to Andrew for many excellent suggestions to improve this thread And to Afmob for making all the extra pics; and again to Andrew for the solutions Another way to view all the original Assassins (and Texas Jigsaw Killers) from enxio27 Andrew And I'll add a very big thankyou to Richard for his SudokuSolver software and to Ed for the massive amount of work that he's done, together with Richard, on SS scores. Thanks also to Børge for generating so many diagrams, which are also in the Images with "udosuk Style Killer Cages" thread, and for providing links from diagrams in that thread to the archive entries. And many thanks again to Ed for useful suggestions to improve this page and Archive Part D after my first few posts in them. 2012 Thanks Ed for suggesting that the title of the main Archive page should be updated when further entries are added to the archive. Thanks Ed for suggesting that this index should include a list of walkthroughs added since your parts of the archive were completed. |
