4 wheel drive
I just posted two new puzzles and as always, there is something special about at least one of them :). The “classic” Sudoku puzzle is a 4×4, not 3×3. Use LETTERS A-P to solve it instead of digits!

Let’s work […]

Sorry that I missed to post yesterday’s puzzle – it has been a really hectic week for me. I also thought that the Samurai X should keep you busy for a while. Anyhow, I’ve uploaded the solutions to the previous puzzles and also two brand new puzzles just for you. I hope you notice the […]
