So, I recently got into
Sudoku, which is a great little time waster. You can peruse the site and view some of the puzzles there. I get The Independent, a local publication, everyday just to play the five different Sudoku puzzles it has. Recently my roommate Jamie clued me into
The Dion Cube. This is a Sudoku puzzle in three dimensions. It calls itself the Ultimate Sudoku Puzzle.
I'm not inpressed. I spent a couple of hours on it total, and that was only because I was being stupid. I am now completely finished, and my answers check with those online. What a friggin disappointment.
