I have a couple of questions about <a href="http://sudoku.com/">Sudoku</a>. [mi] <br /><br /> Firstly, is there any freeware out there (windows, not Palm) that will generate Sudoku puzzles? <a href="http://sudoku.com/buy.htm">US$15</a> is a bit steep for a trivial distraction.<br>
<br>
Secondly, is there an algorithm for generating these puzzles yourself? I assume that you can't just throw down a handful of numbers into a grid and have it turn out as a solveable Sudoku puzzle, so I guess it'd have to be an algorithm that generated a 'solved' puzzle and then took out most of the numbers. I guess there's also an algorithm for working out which numbers to remove and which to leave depending on how difficult you want the puzzle to be.post:ask.metafilter.com,2004:site.12868Sun, 12 Dec 2004 21:18:21 -0800obiwanwasabisudokugamespuzzlesfreewaresoftwareBy: zelphi

I'm not sure if there's a freeware version of this, but <a href="http://www.pro.or.jp/~fuji/java/puzzle/numplace/makesudoku/sudoku01.html.en">here's</a> a set of instructions on how to generate puzzles.comment:ask.metafilter.com,2004:site.12868-223392Sun, 12 Dec 2004 21:22:56 -0800zelphiBy: obiwanwasabi

<a href="http://groups.google.com.au/groups?selm=6rg9qi%245hg%241%40ruby.ucc.nau.edu&output=gplain">This post</a> in rec.puzzles discusses an app called "Single Number" by Yoshimitso Kanai. Apparently it has a 'book mode' of 50 specially-crafted puzzles, each of which must be solved before the next can be opened. I can find a <a href="http://www.pilotzone.com/palm/preview/34290.html">Palm version</a> of this app - does anybody know if the 50 puzzles are available elsewhere, or ina Windows app? Guess I can always run a Palm emulator...comment:ask.metafilter.com,2004:site.12868-223425Sun, 12 Dec 2004 21:56:03 -0800obiwanwasabi
