In the first place I would like to thank Simon Anthony (Cracking The Cryptic) and Bernhard Hobiger (HoDoKu), who inspired me to set up this website.

Simon Anthony often talks about the beauty of sudoku logic. This site is about the beauty of analysis-, design- and programming logic. The goal of this site is to inspire people to dive into the wonderful world of software development using modeling techniques like UML, the Unified Modeling Language.

So here UML is used to build up a sudoku webapp from scratch.You can find the resulting app and the source code under the Sudoku menu. On a desktop you can find the sourcecode under your browsers' menu as well . Examine how the app has been developed, examine the code, play sudoku and have fun!

Let's start the development process of the app with a basic use case outline,

Use case Solve sudoko:

  1. Load a hard sudoku puzzle
  2. Apply basic sudoku logic until the app gets stuck
  3. Apply advanced sudoku techniques to break the puzzle
  4. Check your solution
