Generously stocked with puzzles and options, and with something to offer for players of all skill levels, Buku Sudoku is actually one of the strongest puzzle packages on Live Arcade and - somewhat to my surprise - comes highly recommended.
Whether you're a Sudoku vet looking for a new challenge or a newbie wondering what all the fuss is about, Buku Sudoku does a fine job of bringing the phenomenon to a digital audience. Its only real shortcoming is that in some cases, it is content to be complacent, rather than moving the genre forward.
It's tough to justify recommending a ten dollar purchase for Buku Sudoku when there are pen and paper alternatives out there that are both cheap and portable.
Buku Sudoku is worth your time but it won’t replace your pen-and-paper version.
Sporting high-resolution visuals and a comforting soundtrack, the only major addition is multiplayer, but we didn't encounter many challengers online, since this is a game that most people want to play by themselves.
