Hey everybody, this is Dan (h3lix). I used to be active on the djape.net forums a couple of years ago and before I went on hiatus, I started a book project. Now that summer's here and I've had a little more time, I finished it!

Anti-Chess Killer Sudoku

This book contains 112 hand designed puzzles that explore the combination of Anti-Chess and Killer variants with puzzles ranging in difficulty from Beginner to Insane. The book's difficulty is geared more toward advanced solvers, but there are also instructions and tips for beginners and people unfamiliar with killer or anti-chess variants.

100% of proceeds will go to Architecture for Humanity, a nonprofit organization that brings design and construction services where they are needed most, especially in parts of the world that have been devastated by recent earthquakes.

Here's a sample puzzle (not from the book)
Anti-Knight (no two cells one knight's move apart [1,2] can be identical) Killer - Medium

Here are the cage codes for JSudoku or PerfectSudoku. I don't know if they're still the standard cage format.

I'll hang around these forums and post new sample puzzles every week.

Good that you are around again. I'll buy it.

Nice puzzle, I'll try it again on paper tomorrow.

Give my fairy samurai a try - you should enjoy it.

Maurice: Thanks! I'll give it a shot as soon as I can, it looks fun.

Børge: Thanks for the alternate images. I'll download SudokuSolver and figure out how to make them for future puzzles.

Good luck :cheesey:



I have NOT made the images with SudokuSolver, but with an Excel program I have programmed myself.

I can paste in any PS, SumoCue or tarek code, and the corresponding B&W image is drawn automatically.
A cell in one or more cages can then be selected, and by pressing a button these cages are coloured with the colour assigned to that button.
Please click the above link for a screen shot.

well...never mind then. :?

If you guys are on Facebook, I just made a page for this project, where I'll also be posting these sample puzzles as well as giving updates (available on amazon, payment made to AfH, and so on)

This is slightly off-topic but anyways,

Børge, why don't you make your program available so that anyone who wants to have puzzle images this way can create them?

I think this would be a better solution than posting an image everytime a new Killer related puzzle appears even though most of them already have one.

My previous post was only meant as informative, so that you would not futilely spend time on trying to figure out how to make what I have named "udosuk Style Killer Cages" using SudokuSolver.
You can make nice images with SudokuSolver (link), but AFAIK the colouring is done automatically so you cannot control which one of the 6 customizable cage colours a specif cage is coloured with.

The term "udosuk Style Killer Cages" is a tribute to the board member udosuk aka Matt, who also is a member of several other sudoku fora. Unfortunately he has not posted something for the past seven months.
AFAIK udosuk originally created this very pleasing way of presenting killer puzzles using Excel, manually drawing the cages.
I originally thought he produced his images using JSudoku, but learned differently.

After learning from udosuk how he "configured" Excel to produce his distinctive cage look, I made some myself, then wrote some code to alleviate the colouring and later wrote more code to draw the cages automatically from PS, SumoCue or tarek code. The initially goal was to make a releasable version of my program and give it away. Unfortunately I have not reached this goal due to the following obstacles:
  • Lack of time.
  • Incompatibility between Excel versions, and bugs in Excel 2007.
    I have done most of the programming with Excel 2003.
    The diagonal connector and connecting tubes are actually Shapes. When you in Excel 2007 rotate certain Shapes, they are also scaled, which in my opinion must be a bug.
  • Undesignedly use of a feature (UpDown controls) which is not present in non-professional versions of Excel XP(2002) and later.
    This problem can be solved by replacing the library mscomct2.ocx with the professional version freely downloadable from Microsoft
    http://support.microsoft.com/kb/297381
Instructions:
Windows 95, 98, or Me:
======================
1) Move the file MSCOMCT2.OCX to C:\windows\system\MSCOMCT2.OCX
2) Using your mouse, click on the "Start" button and then click on "Run".
3) In the new Run window enter the followin string and click the OK button:
regsvr32 \windows\system\MSCOMCT2.OCX


Windows NT or 2000:
===================
1) Move the file MSCOMCT2.OCX to C:\WINNT\system32\MSCOMCT2.OCX
2) Using your mouse, click on the "Start" button and then click on "Run".
3) In the new Run window enter the followin string and click the OK button:
regsvr32 \WINNT\system32\MSCOMCT2.OCX


Windows XP, Vista or 7:
=======================
1) Move the file MSCOMCT2.OCX to C:\windows\system32\MSCOMCT2.OCX
2) Using your mouse, click on the "Start" button and then click on "Run".
3) In the new Run window enter the followin string and click the OK button:
regsvr32 \windows\system32\MSCOMCT2.OCX


As a solution I have started to reprogram it in C# with .NET, but are very far away from a release.

If anyone wants to try my program I will happily make it available as is, but please be aware of the following:
  • You very likely have to replace the library mscomct2.ocx, unless you have Office professional or are using a PC, which previously had Office 2000 or older installed.
  • Diagonal connector and connecting tubes are not drawn with Excel 2007 and 2010.
  • Macros must be allowed, although I would not call approx. 6000 lines of code a macro.

I will not lock the VBA code, so anyone interested can access, use and modify it freely.


EDIT:
@afmob:
I was typing my post, which took I while, when you posted your above post.

Yeah, Matt was a great part of the community on the djape forums, he always gave me great feedback for my puzzles and was a whiz with excel. Hopefully he's okay, he seemed overdue for a burnout.

Can the spreadsheet handle diagonal cage links? I am looking for a means of displaying images for future puzzles that leaves less room for error and looks a little cleaner than JSudoku. I've been using PerfectSudoku for cages, adding diagonal connectors manually as necessary.

By the way, my book is now available on Amazon! http://www.amazon.com/Anti-Chess-Killer-Sudoku-Daniel-Adams/dp/1452836078/ref=sr_1_1?ie=UTF8&s=books&qid=1273451715&sr=8-1

Absolutely, but NOT with Excel 2007, due to a bug.
There are two kinds of diagonal cage links, which I call diagonal connector and connecting tubes, and I use Shapes to represent them, as did Matt. When you in Excel 2007 rotate certain Shapes, they are also scaled, which in my opinion must be a bug.

Connector tubes are between non-remote cage parts, and connecting tubes are between remote cage parts.

As afmob suggested, I will make my program available ASAP, hopefully no later than next weekend (May 15-16).
I will not have time to write a full user's guide, but will mention the most important stuff, and then we can take it from there.


Here some examples. All are 100% authentic screen shots without any kind of post processing:
