Quick Start

When you start Sudoku Champion, it opens with a newly generated puzzle for you to solve. Every puzzle has a unique solution. Sudoku Champion always highlights the currently active cell by drawing its border in red. To change the value of the highlighted cell, just type a number from 1 to 9 on the keyboard. Typing 0, delete or backspace will clear the current value of the cell. You can move the active cell with the arrow keys or by clicking a different cell with the mouse. While you solve the puzzle, Sudoku Champion offers you different types of help:


How it started

I wrote Sudoku Champion as an excercise since I was learning C#. The best way to learn a programming language is to actually write a program and learn by doing. I got the idea to write a Sudoku program from Léonie Fierz (who is no relation of mine): She was a student in a Science course for Swiss youths, and told me that she was supposed to write a Sudoku program as an assignment in class. I was motivated to write Sudoku Champion when I saw the most beautiful woman of the clinic Königsfelden solve one on the train from Brugg to Zürich. I finally started writing it in march 2006 in my mountain retreat in the Engadin.


Thanks to Stefan van Ekeren for beta testing, and Andreas Umbach for helping me with the flicker problem.
