I have written a Sodoku Solver in java, with an interface in swing. I have only managed to implement techniques up to Naked Triplets, which is pretty feeble i know! However, i was just wondering, do any of you know where i could find a text file full of puzzles that would be solveable with techniques up to Naked Triplets? I have a button in my interfce which takes puzzles from a file and displays them to the user to play, but these need to be solvable if the user gets stuck! Appreciation in advance, Darren Back to top Ruud Site Admin Joined: 17 Sep 2005 Posts: 708 : Location: Netherlands Items Posted: Thu Apr 13, 2006 12:51 pm    Post subject: Hi Darren, how many do you need?

I would probably need a minimum of around 200 puzzles or so, but anything over that would be welcomed Back to top Ruud Site Admin Joined: 17 Sep 2005 Posts: 708 : Location: Netherlands Items Posted:

Thank you so much for your help! My project demo should now look a bit better And also to say, i have played around with Sudo Cue, it is fantastic. I have also had a play around with Simon Armstrong's and Bob Hanson's solvers, the stuff i aspire to! It is only really when i tried to do this that i realised how tough it is, although my programming is not the stongest.

I now have my solver online. And my project is due on Friday! I have one more request, as part of formally testing the modules of my solver. Do you have puzzles stored that require certain methods to solve them? That is all techniques up to that standard. The categories of puzzle i am looking for are: Single Candidate Hidden Candidate Block / Row / Column Interactions Block / Block interactions Naked Pairs Naked Triplets If you had between 5 and 10 of each type of puzzle, it would be really appreciated!
