NZGamer writes: "Sudoku doesn't seem to be one of those games that are suited to a heavy console tied to the home. A portable version might be understandable, but it seems a bit odd to have a version available on XBLA. However, for better or for worse, Buku Sudoku is now available for download. So, what can fans of Sudoku expect?
Well, in terms of presentation, Buku Sudoku is a relatively barebones experience. While players can certainly customise backgrounds, music, and themes, there really aren't too many ways you can tart up Sudoku.
However, Buku Sudoku allows for a variety of gameplay styles. Players can choose board sizes and whether or not they want to be able to cheat have the computer help them."
