The Sudoku Variant of the Day is Hanidoku, which I discovered at Michael Mepham’s Daily Sudoku site. Hanidoku uses a hex-based board instead of a grid. As a longtime sudoku variant addict, I thought I’d start with the Moderate example, but it turned out to be pretty hard for a beginner.

There’s a whole site devoted to Hanidoku already with a daily HaniDoku, hints, and free Hanidoku software. You can also find some quick hints in this discussion thread.
