Generate and solve Sudoku examples
The problems generated on the site, and any other services of the site, may not be used in any public/commercial service.
Now that we're over that, let's see what you can do here. Here you can find a description, which explains the methods used by the program to generate and solve sudoku examples, and the criteria by which they are scored. I recommend that you read this before you start solving them: these examples can be very difficult. The solutions to the examples are always clear, and their difficulty levels can range from 0 to 100, although not all levels of difficulty are available (you can click the Explore button to see what level of difficulty the problem is). For comparison, among the Sudoku examples that appear in in newspapers (unless they were written down), I have not yet found one that is more difficult than level 2. With human reason, examples with a difficulty level of about 7 can be solved. All sudoku fields can be modified, but the ones marked in gray were already filled in. We can request the solution with a (detailed) analysis, when the program describes the solution step by step with the applied methods in a PDF file.
Have fun everyone, and I look forward to suggestions regarding the site.
