Just a quick update.

I relaxed the SudoKai v3.0 registration restrictions.

So now you only have to deal with the annoying news page being in the way.

SudoKai v4 (Limited Edition) have been released.

It can now handle many more Sudoku Puzzle Variants and then some. This is mainly why development took so long as I had to solve some nasty Sudoku Programming Challenges I set myself, and yet many more awaits me.

I have included as many Sudoku Variants as I could in order to showcase SudoKai's capabilities. Depending on how well SudoKai v4 is received, more Sudoku games and variants could be included in future releases.

Some of the new Sudoku Games and puzzles include:

Sudoku Parquet
Will Sudoku
Tight Fit Sudoku
0-9 Sudoku
10x10, 12x12, 15x15, 16x16 Sudoku Boards

If there are any problems, please let me know.

SudoKai v4.2 (Limited Edition) have been released.

Not much have changed, only a few minor tweaks here and there.

The only major enhancement is the release of the SudoKai Board Layout Manager/Builder.

Additionally, here is an old Topic that may need some revival

I have uploaded a basic SudoKai version for online playing.

More features and Sudoku variants will be added at a later stage.

I am trying to reach the creator of this software Sudokai v4. Is this program being developed further, what is needed?

Does anyone know are there software like this one (with special sudoku styles) but that can generate new puzzles not extract from the premade selection?

Thank you.

[creint]

There are a lot of tools. Can you give examples on what it must contain?
Do you have an layout that you want to try?

Most of the tools are aimed at solving and a bit explaining.
Some can generating specific variants. Generating constraints is much harder than removing digits.
Very few have design features.
No tool has everything.

If you can add constraints and solve those then you can manually generate puzzles.
If you have the puzzle then you can manually design the layout.

Examples:

Dynamic symbols in cell
Free cell arrangement
Manual adding constraints, alldifferent or others
Finding solution
Displaying solve steps

You can try Penpa edit for design.

I am trying to reach the creator of this software Sudokai v4...

No further releases are planned for SudoKai as it is not in high demand. Seems everybody is interested in 9x9 Sudoku only.

I have also not come across another Sudoku application similar to SudoKai which allows the creation of exotic Sudoku variants.

Additionally, SudoKai comes with a puzzle generator - more information in the PDF help files which was uploaded here: https://archive.org/details/sudokai_v4

Perhaps SiSeSuSo comes close to SudoKai...

SiSeSuSo is not bad and has lots of potential.

SudoKai however comes pre-loaded with these (and many more) exotic Sudoku variants:

Sudoku Parquet
Will Sudoku
Tight Fit Sudoku
0-9 Sudoku
10x10, 12x12, 15x15, 16x16 Sudoku Boards
Sujiken
Tridoku (incl. Hoshi and Star)
Hexagon variants (incl. Hanidoku)
3D Perspective variants (Isometric Sudoku, incl. Cubic and Tredoku™)

SudoKai is now free - so you are welcome to give it a try and also use it as a reference.

[creint]

JSudoku is maybe an option too.
SiSeSuSo has for now only support for digits 1-9 and sudoku grids.
My solver can probably solve all puzzles from SudoKai and more. Generating is also possible. Supports most paste-able formats.
More appearance options are available in SudoKai, but adding constraints is harder.

Sounds amazing, just let us know where we can download your Sudoku app. Thank You.

@Sudokai

Thank you for replying. I was nott notified there was a reply here.
I tried to connect with you over Twitter but maybe you do not get notifications.

I am aware there is no huge demand for exotic puzzles, but one reason could be - people have no idea they exist. Names are unique, appearance is specific, only true puzzle lovers and members of forum like this one will know these special puzzles exist.

I love LOVE unique custom weird less known puzzles and I also develop an design my own. I was looking for maze sudoku and by coincidence discovered Aenigmatics books that made my mind explode. I could not find anything about the puzzles so I hired someone on Fiverr to investigate which resulted in finding Sudokai, but with no way of reaching the developer.

In regards to what I need (or what other needs) from puzzle generating software, something like Cross + A. That program generates over 400 logic puzzles including a lot of sudoku puzzles, in SVG (and all other file formats) and exports puzzles and solutions. It is the perfect software for puzzles.

I tried exporting 100 puzzles using Sudokai but I can't figure out how to export their matching solutions. And end resolution is very small, it should be at least 3000px on one side and 300DPI. For this SVG export is the best solution.

The program allows me to enter numbers from 1 -1001. If I understand correctly, that means if 1000 people select 3, 5, 7, 11, 13, 17, 19, 23 and 29 we will all have 9 identical puzzles?

How complicated and is it at all possible to upgrade code to generate a unique puzzle with a single solution?

If possible, what would be the cost and timing?

@creint
Thank you. I can't seem to find a gallery with sudoku puzzle images that are included in the SiSeSuSo program, does it have more or less options than Cross+A?

You should be able to get a larger image if you zoom in first before generating puzzles to files - this does slow down puzzle generation.

As for not saving the solution alongside the puzzles, did not think to include it at the time - Bad and lazy programming. So for now you have to open up each SudoKai file to get the solution.

Yes - 1001 Pre-generated Sudoku games.

...How complicated and is it at all possible to upgrade code to generate a unique puzzle with a single solution?

Every puzzle SudoKai generates is unique and does have a single solution.

...If possible, what would be the cost and timing?

Maybe somewhere in the future I will get back to enhancing SudoKai, but as mentioned before - no further releases are planned for SudoKai.
