A few weeks ago in a Belgium magazine called Humo was a Sudoku variant I did not know yet. It is called ChaoSudoku.
Unfortunately this magazine ended up in the paper recycling bin (what is good for the environment) but now I was unable to scan it and publish it right here. The nine, 3 by 3, squares are replace by random shaped boxes with space for still the nine digits you need to enter within the Sudoku. The rule that in each column and row must completed by the digits one till nine is still valid. Some ‘Google-ing” did not help me much.
Luckily I found a Dutch website called Tazuku where they explain the ChaoSudoku in Dutch. You can use Babelfish to translate the webpage or just look at the images which will explain it all. If you know where I can find ChaoSudoku’s on the internet please let me know. Happy Puzzling!
