If you have an iphone, you can play Sudoku on the go. While the iphone does not support a native Sudoku application, you can play online web Sudoku that has been formatted for the iphone's smaller screen and touch screen interface.

So far, there are not a lot of options, but a couple of them should offer a compelling Sudoku experience.
