Try integrating it with a user interface like this example: http://www.vantasyworld.com/fun/sudoku/sudokusolver.html.

Does it also detect sudoku puzzles that are impossible to solve?

This solver I have been using works fine but it is alot of code compared to yours!

I can’t get it to execute.

I assume I need the first part, select from dual, then the model clause (model reference xxx on …. dimension by (i,j) measures (r), then followed by the “main solve” clause?

I keep getting syntax errors trying to run it, in 10.2.0.3.
