Major Site Update
by birdman5 » Fri Dec 02, 2005 12:57 pm
Recent improvements to the site: http://www.sudoku.uk.com
Picture Sudoku!
Behind each puzzle is a picture. You must solve the puzzle to see it in full. Submit your own pictures and puzzles to truly personalise your sudokus!
Sudoku Solver.
Manually add a puzzle from your local newspaper or book, and get the full solution. Alternatively, you can upload or copy and paste in. You can save the completed puzzle to email to your friends.
Improved solver.
The solver now takes a more 'human' approach. It will try the simplest techniques first, then will get increasingly more complex in order to find the next number. As soon as it finds a number, it will revert back to the simple techniques again.
Undo / Redo Added.
You can now go back if you make a mistake, or forward again if you so desire.
Solutions Added.
You will now be shown when you enter an incorrect answer. The offending cells will be shown in red. You can either Undo your entry, or just remove it manually. Remember to save after fixing it.
Step and Solve options removed.
These were removed because i thought it they take the fun out of Sudoku, and also because they quickly show the picture behind the puzzle, again ruining the surprise. They may return one day, who knows...
Login.
The site will now remember if you have logged in before. This is done using cookies, so if you delete them, you will have to login again.
My Profile.
You can now change some settings for the puzzle. If you want to show the 'pencil marks' against each cell on the grid, you can. Likewise, you can have these removed when showing a hint. Finally, you can remove the picture from the grid (as if you'd want to!).
Sudoku Techniques.
A full, graphical rundown of all the techniques used by the sudoku solver.
Discussion Board.
Ask any sudoku related questions here.

The solution is available here--select "express" and enter the numbers 14479
Do you have a link?
When the site say's a puzzle is not solvable, it means it is not solvable using the current programmed logic. The solver on my site only uses some of the techniques available to solving puzzles. I did this to keep the solver as 'human' as possible.
More advanced techniques may be required for your puzzle. If you add it here, i can tell you exactly what is needed
