For some reason that link gives a 404 error. Try this version of it: http://www.easysurf.cc/su-doku.htm

Transcription errors

Postby lunababy_moonchild » Sun Apr 10, 2005 2:05 pm

The trouble with this is the possiblity of transcription errors. That and differentiating clues from numbers written in, although you could use pen for clues and pencil for solving. Which is why I have mine transcribed into Excel.

Liked the giant grid though - we need more of those imo!

Now, if we could just figure out a way of transcribing the sudoku program puzzles into a giant grid (with giant numbers, of course) in Excel (or indeed, anything else for that matter), we'd be sorted!:D

Thanks for the suggestions though

I agree the general strategy, but Step 7 ' "Then look to see if you can eliminate any of the possible numbers that you have already written at the top of each empty cell. Cross out those numbers", understates the complexity of some of the rules for the elimination of digits.

My Solver Program works exactly as you decribe - but step 7 is now a very large (and often complex) series of sub routines.

You can cut and paste the puzzles from the Times website into MS Word and then just enlarge the grid to what ever size you want it ( by double clicking on th grid and then dragging the botom right corner of the grid downwards and sideways). Mind you it does mean you have to wait for the puzzles to appear on the site so you are always a few days behind everybody else!

Dots

Postby Guest » Mon Apr 25, 2005 11:42 am

In order to save space and use the original puzzle, I use dots. So if 1 is a possible value, i put a dot in top left corner. 9 is bottom right etc.
