Do you like Sudokus? If yes, you can downoad here 666 of them.
This should take a while to solve them all.
You can choose between 3 difficulties, each zip file contains 222 Sudokus.
Do you have problems with solving? Never say die! Solutions for all Sudokus are included. Isn't it nice?

I posted the photo sudoku on p-paper & iLiad in the gallery.

Sudoku For Dummies or WTF is Sudoku?:
short version [thanks to Alexander Turcic]:How to play: Fill in the grid so that every row, every column and every 3x3 box contains the digits 1-9. There's no maths involved. You solve the puzzle with reasoning and logic.
long version: wikipedia

Is sudoku a math problem? You can discuss it here.

Q: 666 sudokus are not enough for me. What can I do?
A: You can create your own ones! I used pysudoku to create them. I found it here.

Or is it ok for you that they are non-quadratic? At the moment the 666 Sudokus are a bit rectangular. There are 2 ways to get quadratic Sudokus:change the size of the png image [pysudoku command] to dimensions of a square [the problem is: then you get an annoying black bar in the bottom of the iLiad screen, so you have to resize the bottom & top margin in a batch in your image editor, I can do this if somebody wants quadratic sudokus.], or to change the sc of pysudoku [in detail: the margin settings; mmmh, I have no perl compiler] : # How many sudokus did you solve already? # Are the "hard" ones too easy for you?

I've only just started on yours, because I was finishing the ones I had already downloaded. Thank you, by the way.

Yes, python runs nicely on the iLiad. Yes, you can create more soduko PNG's using it.

I already installed it. More information later. This package can create & solve sudokus, this is what we want. With the help of geometry package we should get iLiad compatible sudokus.

This way you could get daily sudokus included in the same PDF that you're using to read RSS feeds. The goal is to recreate the whole newspaper experience but on e-ink devices, and I do believe that sudokus are part of it. The LaTeX package makes great looking sudokus but I'm not sure how I'll generate these yet. I guess that using an algorithm + allowing people to create sudokus directly on the website would be the best solution, this way you could subscribe to someone sudoku's feed.

Ok, I tested the metioned LaTeX package sudokubundle.
tex file is included.
Next step will be to generate sudokus with \generategrid[file].

the same images as uploaded in post 1, but now included in one pdf file.

Thanks to new 2.8 feature, you can scribble in pdf files.

fake FAQ:
pdf files are a bit large [~ 4 MB]. Could these files be smaller?
Yes they could, but it was easier to embed the already existing images in a pdf file.

But I am getting sick of always needing a pencil and eraser and dont like using the PC for it. So, I want one for the iliad. Any suggestions ? Last edited by drlolly; 01-22-2009 at 06:04 PM.
