I came across this amusing post on the blog Creating Passionate Users that imagines what would happen if sudoku were (re)designed by Microsoft. I grabbed the image below from the site.
The post also has a brief discussion of how the puzzle’s simplicity makes it appealing.
Hi,
I’ve made an online Sudoku MULTIPLAYER mode (2 players). http://www.SudokuCombat.com provides puzzles in easy, medium and hard levels. SudokuCombat is free and fully web 2.0. No subscription required, no crappy java applets, no advertising. Just fun!
