Sudoku (part 2)

Concerning the previous Sudoku post: The best online implementation is probably here. It's written in Flash, you can easily copy it to your hard drive.

The best FREE implementation for Palm PDA is here (although the random puzzle generator currently sucks). There are other (non-free) implementations.

And no, really, I've never before heard about Sudoku (also called "Number Place"). I don't read printed newspapers.

UPDATE: The Flash page linked above generates puzzles (on "Hard" setting) with more than one solution! I guess these are not valid Sudoku puzzles...

UPDATE 2: "Anonymous" wrote that "official Sudoku puzzles" actually have to be symmetrical (which is NOT true for most of the puzzles I found on the web). See Wikipedia entry.

Sudoku in your link is missing one of the basic rules for the puzzle creation. Symmetry!

That's interesting. Most of the ("so-called") Sudoku puzzles I found were not symmetrical.

Why do you use special version for PDA and not just play with the Flash version on your handheld? Macromedia published Flash plugin for PDA long time ago...

Oh, now i see... you use Palm and the plugin is only for Windows Mobile. Thats strange, i thought that Macromedia ported Flash plugin for virtually every mobile device.

Sudoku and SYMMETRY? what the heck? i have read tons and tond of articles about sudokus and their history, own a book on it and have a sudoku-generating software for my mac. I have never ever seen anything about symmetry. but when i take a look they are symmetrical... no, not all of them. whew

the flash one isn't that good since it generates puzzles, that can be solved in more ways
