This is a repost of my message on the Sudocue forums, in case those go down. I've also posted it to the forums at EnjoySudoku.com.

I've been "collecting" a bunch of Ruud's specialty puzzles that aren't found in the usual Sudocue archives--puzzles he's posted to various forums, etc. A few of these gems are on his specialty page, often accompanied by amusing descriptions (I've included those where possible). Here's what I've found so far, listed in chronological order by posting date. I hope you enjoy these.

Celebrity Killer (August 1, 2006)
Mentioned in Ruud's description of the Mystery Letter Sudoku at http://sudocue.net/special.php

Here is a list of names that you can use to determine the cage sums:

A = Shankar
B = Ball
C = Ono
D = Schindler
E = Kennedy
F = Krupa
G = Pritchard
H = Hampton
I = Mandela
J = Cage Cool
K = Flynn
L = Lovell
M = Fitzgerald
N = Patton
O = Shuster
P = Appel
Q = Welles
R = Kreiski
S = Guinness
T = Bohr
U = Piaf
V = Gillespie
W = Callas
X = Teller
Y = Barbera

To make this puzzle a little more RUUDICULOUS, I'm not telling you how to convert the list of names into cage sums, but you'll figure that out soon enough.

12x12 DG (September 8, 2006)
Found at http://sudocue.net/special.php

12x12 Sudoku with Disjoint Groups. The given numbers have horizontal and vertical symmetry, which fits nicely with this format. You need more than just singles to solve it. The Disjoint Groups constraint may not be familiar to you. Every cell that has the same relative position in each 3x4 box must contain a different number. This extra constraint helps you solve the puzzle, but it is very hard to check, certainly in such a large puzzle.

Crossword Killer 1 (September 15, 2006)
Found at http://sudocue.net/special.php

This puzzle is a mix of Killer Sudoku and Word Finder. Only a part of the 9x9 grid is covered with cages. The numbers in these cages must add up to the given sum. The cells which are not covered by cages must contain valid English words. For instance, there is a horizontal word of 4 letters in row 1, sharing the first letter with a vertical word of 8 letters in column 2. The normal Sudoku rules also apply, where you must use the number assigned to each letter. Without the Killer part, you cannot find the words. Without the words, you cannot solve the Killer part. The interaction between these 2 parts makes it one of the most challenging Sudoku variants.

Dear diary. I have created a second Crossword Killer. No need to explain the rules again to those poor addicts. The 9 letter word should not be too difficult to guess, but if they cannot find it, they’d better not attempt to solve the puzzle. Although the set of letters were tempting me, I resisted using unseemly words in the puzzle.

The new Special is a Killer-X with a dazzling cage pattern. The are no single innies or outies. There are no pairs of innies or outies. There are plenty of triple innies and outies. 3 is the magic number. Do not forget the diagonals. They may help.

Sukaku #001 (October 12, 2006)
Found at http://sudocue.net/special.php

I have a new program that can generate a very interesting variant of Sudoku. It is not new, but I’ve given it a new name.

Suuji Kakure
Image

This translates into: “The digits are hidden”. Following an ancient Japanese tradition, I will call it Sukaku.

Complete the puzzle in such a way that each row, each column and each 3x3 box contains digits 1 through 9. Sounds familiar? In a Sukaku, there are no digits placed in the grid. Instead I will give you a grid with possibilities. Because there are no given numbers, the puzzle can be more difficult than the hardest Sudoku you've ever seen. This puzzle is not too difficult. I found some real baddies, which cannot be solved by some of the best solvers, which I will publish at a later date.

While I was fine-tuning my generator, it came up with a remarkable puzzle. Every constraint has at least 4 candidates left. There is no logical move to start with. SudoCue has to start with a guess (using brute force). There are 3 guesses needed with all techniques including tabling enabled.

Mystery Letter Sudoku (October 13, 2006)
Found at http://sudocue.net/special.php

Many people have solved this puzzle by now, thanks to a big hint by Motris. He happens to be a chemist.

This is a little one-off gimmick. To figure out the clues, you need to find a way to convert the letters into numbers. People who enjoyed my Celebrity Killer may think this is similar, but not so. Use the forum if you want to share your insights with fellow addicts. Once you know how to convert the letters into numbers, the Sudoku can be solved with moderate techniques. If nobody has found an answer in a week, I will post a small hint. Good luck with this one!

Mystery Decompression Sudoku (November 10, 2006)
Found at http://sudocue.net/special.php
NOTE: Image is a SPOILER! Read below first!

Here is a new type of puzzle, inspired by a post on the Sudoku Programmers forum. The following line represents a Sudoku. The digits are the given numbers and the letters A, B, C and D replace the empty cells. Each letter represents a decompression instruction like “insert 2 empty cells”. The letters have no specific order. That would be too easy. However, to help you on your way, I will give you a hint: The given numbers form a symmetrical pattern.

Thanks to ocean who discovered an error in this string, but found the solution anyway. The error has been fixed.

Now that the Samurai contest is going, I am honored to introduce to you a new type of overlapping puzzle. This puzzle has 5 overlapping sudokus, like a Samurai, but the overlap is 2 boxes in stead of one. Because the shape reminded me of a windmill, and because I live in Holland, I named this variant Kazaguruma, the Japanese word for windmill. This puzzle can be solved with relatively easy techniques, but you can also use the twin nonets technique to speed things up.

Shaolin-X #001 (X-Treme Shaolin) (November 28, 2006)
Found at http://www.sudocue.net/forum/viewtopic.php?t=418 (forum link is dead)

I post this puzzle here just to show you that I can now create any Sudoku variant you can imagine. Here is a world-premiere: the Shaolin-X. It has 25 constituent Sudoku-X puzzles. 16 in a 4 x 4 formation, connected by 9 in a 3x3 formation. Pythagoras would have appreciated the beauty of these numbers. The total number of cells is 1701.

As for required solving techniques... I'm not sure. You need several moderate and advanced moves, but I cannot tell you the exact list of solving techniques. It has a guaranteed unique solution. I can also guarantee that this puzzle will definitely ruin your family life, if you had any left...

Clueless Shaolin-X #001 (December 1, 2006)
Found at http://Forum.EnjoySuDoku.com/viewtopic.php?t=5099

This is the worst monstrosity I've ever created and I would like to share it with you. :)

The basic puzzle is a Shaolin or Gattai-25. In addition, the blue boxes, when combined, form a 26th sudoku. All overlapping regions (yellow and blue) are clueless. As it happens, 22 additional boxes also turned out to be clueless. All 26 constituent puzzles, including the blue one, are Sudoku-X, so the diagonals also need to contain digits 1 through 9.

As for required solving techniques: think singles, locked candidates, pairs and triples, crossovers, simple coloring and XY-Wings in the diagonals.

Clueless Shaolin-X #002 (February 6, 2007)
Found at http://sudocue.net/special.php

This is a monster that you will only find on this website, because nobody else has the guts to make such puzzles.

Be warned. Be scared. Be prepared to take on this Clueless-Shaolin-X. 26 interlinked puzzles, number 26 being the combination of the blue boxes. Diagonals also need digits 1 through 9 in all 26 constituent puzzles. And of course, all overlapping regions are clueless...

Name that Album Killer (February 13, 2007)
Found at http://www.sudocue.net/forum/viewtopic.php?p=1915 (forum link is dead)

Here's a puzzle in a series that I started on another forum. The puzzle requires 2 answers:

1. The solution of the Zero-X-Killer on top.
2. The name of the album below the killer.

I removed artist and title, so you have to browse your CD collection to find it. It was released in 1996. The killer is Ruudiculous until proven otherwise...

007 Killer-X (April 2007?)
Found at a forum that is now dead. Date is approximate.

This is a Zero Killer-X on the 007 theme. The candidates are two 0s and 1-7; no repeats on the diagonals. This is a "twin" puzzle, both grids have to be used together to obtain a unique solution.

[I don't have the SumoCue code available. Can any of you help?]

Queen's Day Special Clueless Taiken-X (April 24, 2007)
Found at http://sudocue.net/special.php

Each April 30, here in Holland we celebrate an ancient tradition: Queens’s Day. Sort of Independence Day without the "in" part. That day, the Queen and her family go visit and pretend to like their subjects who pretend to like them back. Orange is the color of choice on Queen’s Day.

The following puzzle is dedicated to our beloved Queen. It is Big, Orange and Clueless. All constituent Sudokus, including the 22nd Clueless Sudoku in the blue cells, require digits 1 through 9 in both diagonals.

Catch-22 Taiken (April 24, 2007)
Found at http://sudocue.net/forum/viewtopic.php?t=671 (forum link is dead)

This puzzle is similar in shape to the Queens Day puzzle on the special page, but all comparisons end there. This puzzle is bad, reeeeally bad! The only sure facts about this puzzle are a) it has a single solution b) basic techniques will only solve 26 cells.

The name refers to the 22 constituent puzzles, intertwined in such a way that there's no escape. All constituent sudokus have diagonal constraints and the blue cells form a 22nd sudoku with the same constraints.

Joseph Heller wrote:
There was only one catch and that was Catch-22, which specified that a concern for one's own safety in the face of dangers that were real and immediate was the process of a rational mind. Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. Yossarian was moved very deeply by the absolute simplicity of this clause of Catch-22 and let out a respectful whistle."
"That's some catch, that catch-22," he observed.
"It's the best there is," Doc Daneeka agreed.

22 sudokus with strong links, one of them disjoint, blue and clueless. You know the drill. This one's easier, so no medal for the winner.

To celebrate the return of this forum and get it going again, here is a Gattai-22 with a clueless component. The 21 visible Sudokus are overlapping like a normal Gattai. The blue boxes belong to the 22nd Sudoku.

Moderate solving techniques are sufficient to solve this puzzle, but the sheer size makes it error-prone. To give you an impression: there are 110 hidden pairs in the shortest solving path...

Ronin Samurai-X (May 28, 2007)
Found at http://sudocue.net/forum/viewtopic.php?t=701 (forum link is dead)

In ancient Japan, a Samurai who has lost his master was called Ronin. These uncontrollable outlaws often caused uproar in the country. So much for today's history lesson...

I decided to call this Samurai-X Ronin because it is impossible to master. It has only 70 clues. To give you an impression: The full suite of techniques for the regular Samurai puzzles (with Diagonal techniques added) only manage to solve 2 cells.

If you can avoid bifurcation (a euphemism for 'guessing'), this will be a great exercise to discover multi-grid AIC's, BUG-Lites and coloring patterns. Do not forget the diagonals. They will be needed.

Black Friday Taiken (July 13, 2007)
Found at http://sudocue.net/special.php
A printable version can be found here that is easier on the eyes as well as on the print cartridge.

We were all shocked by a total forum blackout today. Ten years from now, addicts will still remember this day and ask each other: "Where were you when the forum went down on sudocue.net?". They may even write a song about the event.

The following Taiken will make sure we never forget! You need some creative moves to solve this puzzle, but it does not require any trial & error.

Erm ... where do I write pencilmarks?

Holiday Special Clueless Taiken-X (July 19, 2007)
Found at http://www.sudocue.net/forum/viewtopic.php?p=3101 (forum link is dead)

Combining variations and turning them into huge overlapping puzzles is fun, especially when the outcome is a great puzzle. This Holiday Special will keep you busy during those long hours on the beach with no Internet access and too much time on your sweaty hands. 8-)

The format is a Clueless-Taiken-X. Look at all those empty nonets! It's not as bad as Catch-22, but close.

Clueless Windoku-X (August 11, 2007)
Found at http://www.sudocue.net/forum/viewtopic.php?t=624 (forum link is dead)

Here is a fullsize Clueless Wind-X. Each of the 13 constituent puzzles is a Sudoku-X. Of these, 4 are placed in a familiar Windoku pattern and completely clueless.

This puzzle is very tough, but it helps when you discover the twin nonets and the 36 hidden groups. Oops, now I said it! :oops: Happy puzzling!

Jigsaw Center Dot Killer (November 2, 2007)
Found at http://www.sudocue.net/forum/viewtopic.php?p=3945 (forum link is dead)

Here is the fulfillment of the number 4 prophecy. The blue cells can be seen as a center-dot group or a size-9 cage as shown in the picture. Number 4 is jumping right at you. The other numbers are not so forthcoming...

PS: It has (4+4) cages of size 4. This would have been TJK32. (4+4)x4=32. :pallid:

Diagonal Surprise Assassin (November 11, 2007)

Not a V2, but a brand new challenge with unorthodox (unorthogonal) cage shapes. For those who are familiar with old Dutch traditions, you know where those candy colors refer to...

Killer X-mas tree (December 20, 2007)
Found at http://www.sudocue.net/forum/viewtopic.php?p=4278 (forum link is dead)

Here is a V2X of this week's Assassin. It is solvable by logic, but you need a lot of it. Fortunately, you will have a little more time now with the upcoming Holidays, for which I wish you all the best.

With the demise of both sudokuvault.com and the forums at sudoku.org.uk and sudoku.com, many of the image and forum links were obsolete. I have uploaded the affected images to a new location, and updated the links in the above post.

If you see any I missed, or have trouble with any of the image links, please let me know. I am particularly interested in whether the image links require a log-in. Unfortunately, I can't do anything about the broken forum links.

I have now combed through all of Ruud's posts in the still-existing forums he used to frequent, and I've posted all of his specialty puzzles I could find, including the killer, jigsaw, letter, etc. I previously skipped. I've added codes for almost all of the puzzles (help with the codes for a few killers as noted would be much appreciated) and Ruud's often-amusing puzzle descriptions. I've also marked (hopefully) all of the broken forum links.

I am still missing two of his puzzles (no image or puzzle code available at all). If you can help with these, please let me know!

Clueless Jigsaw (September 11, 2007)
Found at http://www.sudocue.net/forum/viewtopic.php?t=793

Celebrity Killer (on or shortly before October 13, 2006) - FOUND!! Thank you, Ed!
Mentioned in his description of the Mystery Letter Sudoku at http://sudocue.net/special.php

Also, I'm missing original images of the following puzzles. I've recreated images using the puzzle codes, but Ruud's puzzle images were usually interesting, and often significant to the puzzle (although not essential for solving). If you have copies of the original images, I would really like to have them.

Name that Album Killer (February 13, 2007)
http://www.sudocue.net/forum/viewtopic.php?p=1915

First 12-Clue Sudoku-X (July 23, 2007)
http://www.sudocue.net/forum/viewtopic.php?p=3142

Jigsaw Center Dot Killer (November 2, 2007)
http://www.sudocue.net/forum/viewtopic.php?p=3945

Diagonal Surprise Assassin (November 11, 2007)
http://www.sudocue.net/forum/viewtopic.php?p=4010

Finally, if you discover one I've somehow missed, please post here so that I can add it to the collection.

Ruud's Celebrity Killer 1 August 2006

Image

Here is a list of names that you can use to determine the cage sums:

A = Shankar
B = Ball
C = Ono
D = Schindler
E = Kennedy
F = Krupa
G = Pritchard
H = Hampton
I = Mandela
J = Cage Cool
K = Flynn
L = Lovell
M = Fitzgerald
N = Patton
O = Shuster
P = Appel
Q = Welles
R = Kreiski
S = Guinness
T = Bohr
U = Piaf
V = Gillespie
W = Callas
X = Teller
Y = Barbera

To make this puzzle a little more RUUDICULOUS, I'm not telling you how to convert the list of names into cage sums, but you'll figure that out soon enough.

sudokued's solution: Spoiler alert!!
Hidden Text:
A = Ravi Shankar yOB 1920
B = Lucille Ball 1911
C = Yoko Ono 1933
D = Oskar Schindler 1908
E = J.F.Kennedy 1917
F = Gene Krupa 1909
G = John Pritchard 1921
H = Lionel Hampton 1908
I = Nelson Mandela 1918
J = John Cage 1912
K = Errol Flynn 1909
L = Jim Lovell 1928
M = Ella Fitzgerald 1917
N = George Smith Patton IV 1923
O = Joe Shuster 1914
P = Karel Appel 1921
Q = Orson Welles 1915
R = Bruno Kreisky 1911
S = Alec Guinness 1914
T = Aage Niels Bohr 1922
U = Edith Piaf 1915
V = Dizzy Gillespie 1917
W = Maria Callas 1923
X = Edward Teller 1908
Y = Joseph Barbera 1911


That was a fun puzzle. Can't find any of the others you are looking for. I remember Richard got the name of the album correct on Name That Album so he might have an original pic somewhere. I agree that Ruud did pretty incredible pcs. Good on you for getting this all together.

Cheers
Ed

Awesome! Thank you so much! Adding it to my original post now. Do you remember where he posted it? I don't recall ever seeing it before, and there was no link in the mention that I referred to in my previous post.

Also, do you have the SumoCue code for that puzzle?

I saw that! I hope you're right. The picture for the Diagonal Surprise Assassin had something to do with traditional Dutch candy.

My pleasure! It was fun trying to keep up with all of his haunts, looking for puzzles he deposited here and there. In one case, I found a puzzle less than an hour after he posted it in some obscure forum somewhere, and he was quite surprised. :) I just wish I had paid more attention to the killers, jigsaws, etc. back then. I would dearly love to see that Clueless Jigsaw. I hope someone here still has it.

Annotated some links in the original post to reflect the demise of the sudoku forums at both sudocue.net and setbb.com.

FWIW, I come and go from this forum, depending on how busy I am at the time (I am, after all, a mom with a family). However, my interest in sudoku has never waned (even when my sudoku time fluctuates). I do poke my head in here from time to time to see whether any new enxio27-solvable puzzles have been posted (almost never). A PM sends me an email, which usually will trigger another visit to these forums. I keep all of the puzzles in this thread on my own computer, as well as several backups, so as long as I can access the Internet, I will continue to make them available to whoever wants them.
